Trek Powerfly 4 Gen 4 Review: Takeaway

The Trek Powerfly 4 is the cheapest electric mountain bike made by Trek. This doesn’t take away from its great components and rideability, though. It’s an eMTB designed for lighter trail riding with its larger wheels that smooth out the bumps on the rough spots. Relatively light yet powerful, the Trek Powerfly 4 Gen 4 is an ideal electric mountain bike that doesn’t break the bank.

Ideal for...

E-bike overview.

The Bosch Performance CX motor gives a real kick with up to 85Nm of torque, meaning that you can pull away on a steep and muddy hill with confidence. Power delivery is smooth so you won’t spin the rear wheel should you push too hard. The Bosch smart system offers enhanced ride control with navigation and activity tracking via the eBike Flow app.

Packaged with the Bosch Performance CX motor, is their Walk Assist mode that helps push your e-bike up those tough hills you’re bound to encouter. The LED remote let’s you enable Walk Assist and control the level of pedal assist you need. The LED lights are bright and easy to see, even in bright sunlight.

One thing that Trek does with this electric bike is fit different equipment to different-sized machines. For example, on the XS and S framed machines, it has a 27.5” wheel size, while on the M, L, and XL sizes have a 29″ wheel. The frame on the smaller e-bikes are also slightly different, offering a curved top tub for sizes XS and S, while frame sizes M, L, and XL have a straight top tube.

Trek has thought about everything, not surprisingly. Rack and kickstand mounts are readily avilable, as well as an integrated speed sensor for those riders looking to use the PowerFly 4 as more of a trekker than a day-rider trail e-bike.

Reasons to Buy

If you want an electric bike but don’t want to empty your bank account, the Trek Powerfly 4 Gen 4 is a very good machine to consider. At the lower end of the premium spectrum, the Trek Powerfly 4 will be worth every penny when it comes to an electric mountian bike that will look after you on the road or trail.

Designed not to embarrass you on the trail, it works well on longer cross-country rides. Its battery will be good for a 35-mile ride on tougher terrain, and the power of the Bosch Performance CX motor will leave you breaking a sweat only if you’re going easy on the battery.

When it comes to speed control, the electric bike won’t let you down even on steep tracks in wet conditions with its Tektro hydraulic brakes, and on 203mm rotors, they won’t fade even if used a lot.

Things to Consider

If you want a genuinely inexpensive electric mountain bike, there are others like the Rad Power brand of electric bikes, but few pack as many high performance components as the Trek Powerfly 4 Gen 4. This isn’t the cheapest eMTB out there, but it is very inexpensive for a high-end machine.

Specs & Components

The specs above come from the manufacturer and may vary from what you’ve experienced. Notice something that needs correcting? Let us know .

Offering up to 85 Nm of torque, the light but punchy Bosch Performance CX motor delivers the power you need for riding off-road, including rapid direction changes and tackling steep climbs as you journey around the woods or mountain.

Its Bontrager XR3 Comp tires won’t go quickly on hard, flat surfaces due to higher rolling resistance, but this isn’t what the Powerfly 4 is about — it’s about fun in the mud and on loose surfaces. As such, the motor won’t achieve great flat-out speeds, but it’ll more than make up for it in raw power over the rough stuff.

The 500 Wh battery on the Powerfly 4 will give you a good day out on singletrack and a reasonably long day in the saddle on an off-road adventure. However, there’s no option for a range extender, so if you’re looking for more than 35 miles per charge, choose an eMTB with a range extender or a 625+ Wh battery.

Leaving your gear at a base while doing singletrack will give you more range, but if you’re carrying your pack on an adventure, this will eat into your mileage. Muddy terrain and foul weather can impact range, too.

Sat in a trekking position, you’ll use your upper body to shift your weight according to riding conditions. This could mean you get tired in your arms, chest, and shoulders after a long ride.

Sizes XS and S in the Trek Powerfly 4 range come with 27.5” wheels, while sizes M, L, and XL come with 29” wheels. Either way, they’ll smooth out the rough terrain.

The XS version of this eMTB hardtail electric bike comes with an 80mm travel SR Suntour fork, while all larger sizes have a 120mm travel fork. Both are well-suited to rough terrain.

Though Trek offers a lifetime warranty on the frame, if you haven’t looked after this e-bike, the warranty may be voided.

Clean the bike and oil its working parts after every ride. Keep an eye on chain stretch — change it when it gets to 1 mm per link, and look out for bent/broken teeth on the cassette and front chain wheel. Also, keep an eye on brake pads and hydraulic fluid. Though the Powerfly 4 is waterproof to an extent, take care when it comes to river crossings, as it isn’t designed for complete immersion!

Being a serious electric mountain bike, the Trek Powerfly 4 also looks the part. The clean lines and nice shapes of the frame along with its overall geometry combine to make for a good-looking eMTB.

The choice of colors is good too, from the loud red and black scheme to the muted gray and black. Overall, this bike looks like it means business when thrown about the tracks and trails.

Trek Powerfly 5 Review

When you purchase through links on our website, we may earn a commission. Affiliate disclosure.

When it comes to hardtail electric mountain bikes there’s an awful lot of choice (if they’re in stock) from the big-name manufacturers. When one of my friends called me last week to say he’d brought a Trek, I was eager to try it out. In this Trek Powerfly 5 review, I will take a closer look at the specifications and share with you my opinions after spending a couple of hours with it on Bodmin Moor .

Introduction

Trek’s mountain bike heritage goes back to 1983 when they released the 850 – fast forward 28 years and they have a comprehensive range of high-end e-MTBs ranging in price from just over £2500 to up to an eye-watering £11500.

At £3750 the Trek Powerfly 5 sits at the upper end of their hardtail range and benefits from the latest Bosch Performance Line CX motor with a 625Wh battery. The Powerfly 5 also boasts Rockshox forks and SRAM Eagle SX 12-speed drivetrain.

My friend had been talking about upgrading his Cube Acid hardtail e-MTB for some time and we’d previously discussed the merits of the Trek. He recently took the plunge and purchased the bike reviewed here.

First impressions

The first thing that struck me about the Trek Powerfly 5 was how stunning the paintwork finish is – it’s a gorgeous bike in the ‘slate/volt’ colour scheme. Mind you, you’d expect nothing short of this on an e-bike costing more than a decent second-hand car!

Although the 17″ frame was a bit on the short side for me, with the seat post properly adjusted it felt quite comfortable. My friend paid an extra £200 to have the optional Bontrager dropper seat post fitted, which is a must if you’re going to be tackling the trails.

Riding some rock-strewn single track the Trek feels sure-footed. For an older rider like me, the Powerfly 5 inspires confidence (maybe a bit too much) and is great fun to ride. Where this e-bike comes into its own is when the trail turns upwards – it’s not the first Bosch CX I’ve experienced but this motor never fails to impress me with its 85Nm of torque. Riding up steep tracks is helped even further by the trail-busting SRAM Eagle 11-50 12-speed rear cassette, meaning you never run out of gears.

Although my ride was fairly brief I was thoroughly impressed with the off-road abilities of the Trek, it’s a great all-around package suitable for beginners, intermediate or the older more experienced cyclist who’s returning to mountain biking after a long break. Below I will go into more detail on the components.

Check out the 2023 Powerfly 5 from Trek

Electric components

The high-end mountain bike world is dominated by either the Bosch CX or Shimano Steps E8000 / EP8 of Brose motors. It’s good that manufacturers recognised the demand for a greater battery range and the Trek Powerfly 5 comes with the Bosch 625Wh power tube battery which is neatly integrated into the frame.

Bosch Performance Line CX

The Bosch Performance Line CX motor benefits from several upgrades over the previous model, most notably the 85Nm torque output offering the rider up to 340% assistance.

There’s the new Extended Boost mode which makes negotiating rocks and exposed roots on the trail much easier, particularly uphill. This means the bike can be manoeuvred with greater agility on technical sections.

Revised e-MTB mode – This ensures the rider is well-prepared for whatever situation the trail has in store. New sensor and motor control functions give mountain bikers a much wider range of dynamic and natural support.

The Bosch motor is smooth and the whine from the motor is quiet and not intrusive. Performance is as good as you will find on a road-legal e-MTB and it adds a whole new dimension of fun when riding off-road.

625Wh Powertube battery

I first rode an e-bike with a 625Wh battery at the end of 2019 and having the extra capacity will ensure riders can spend more time enjoying the trails. The range will depend on lots of different variables but 50 miles should be achievable when riding off-road – check out the Bosch range calculator for a rough estimate of battery range from the 625Wh battery.

Bike components

Quality components are a must on electric mountain bikes at this price point and the Trek Powerfly 5 doesn’t disappoint. I have gone into more detail on the specification below.

The gearing is comprised of an SRAM Eagle single-click 12-speed shifter with an NX Eagle rear derailleur and 11-50 cassette – as the Bosch uses an ISIS-type crank interface, an SRAM X1 crankset is fitted. The drivetrain is finished off with a high-quality SRAM SX Eagle chain.

Braking is provided by the excellent Shimano MT-420 4-pot calipers with 203mm brake rotors – as expected these brakes work well and will provide more than enough stopping power for most riders. I found them to be excellent, and you only need to use one finger for braking.

If found the 120mm Rockshox Recon RL suspension forks worked very well indeed. Although they are at the lower end of Rockshox forks they feature trickle-down technology from more expensive forks and feature Motion Control™ damping which features low-speed compression adjustment to lockout.

Wheels and tyres

The wheelset is a disc-specific Bontrager Kovee Comp 23 with Boost 110, 15 mm thru axle at the front and a Boost 148, 12 mm thru axle at the rear. Tyres are Bontrager XR3 Comp, wire bead, 30 tpi, 29×2.30″ which seemed to handle the damp moorland trails very well. If you wish to upgrade to a tubeless set-up these wheels are tubeless-ready. The hub is a standard 9/10 speed Shimano freehub.

Frame and finishing kit

For the frame Trek use their Alpha Platinum Aluminium which is their premium lightweight aluminium designed for maximum strength and minimum weight. As I’ve mentioned above the finish is exquisite and looks incredibly hard to wear.  The frame also benefits from internal routing for lights (should you choose to fit them) and a direct kickstand mount.

All of the finishing kits are all by Trek’s in-house brand Bontrager which is of excellent quality. This bike also had the optional Bontrager Line Dropper seat post fitted which costs an additional £199.99.

If I was in the market for a capable hardtail electric mountain bike I’d be very tempted by the Trek Powerfly 5. It’s great fun to ride and feels very capable on a rough single track – the handling inspires confidence and that Bosch motor is the icing on the cake!

There are cheaper options available and if you’re new to electric mountain biking you may not want to spend quite so much on your first purchase.

Having said that, if I had the money to spend on a nice hardtail e-MTB the Trek would certainly be on my shortlist. Other plus points are the excellent brakes, SRAM 1 x 12 gearing and the 625Wh battery.

My friend has brought this e-bike with the intention of keeping it for a good few years and I’ll post any relevant updates here.

Thanks for the review, even though I discovered this after buying my Powerfly 5, I still found it useful and relatable. I picked mine up in November and have given it a good testing over the winter months – what a brilliant bike! Even though I could have spent less for a Cube reaction, which I almost did. I’m glad I spent more on this. The only issues I have encountered are tyre pressures since going tubeless, but I think that’s more the tape inside rather than the rims thenself.

First Ride: The Trek Powerfly E-Mountain Bike

Trek's pedal-assist mountain bike is wildly popular in Europe—and it just made the leap to the US

Now, four models will be available in the US: the Powerfly 5, women’s Powerfly 5, Powerfly 7, and Powerfly FS 8. The Powerfly 5 and 7 are 29er hardtails, and the Powerfly 5 WSD is a 27.5 hardtail, while the Powerfly FS 8 has 27.5-plus wheels and full suspension. 

The FS’s geometry is trail-oriented: It’s a long, low, slack aluminum bike with 130mm of rear suspension. It includes lots of Trek’s new tech: the Straight Shot down tube, which cuts a direct line from the bottom bracket to the head tube, paired with a Knock Block headset and stem, which prevents the fork crown from striking the (now lower) downtube. Boost-width hubs (110mm front and 148mm rear), Full Floater suspension with Trek’s patented ABP pivot at the rear axle, and 27.5-plus tires finish up the buzzwords. The brake rotors are big—200mm up front with a 180mm rear—which helps increase stopping power and control on this heavy, powerful bike. The bike also uses Trek’s Mino Link suspension design, which has two positions, high and low, allowing the rider to alter the head tube angle by a half degree and change the bottom bracket height by a few millimeters. It’s sold in the high position, so riders can choose to get slacker. 

The Powerfly 8 FS is sold with a Rockshox Yari RL Solo fork and Rockshox Deluxe RL shock, Sunringle Duroc 40 rims laced to Bontrager hubs, Bontrager Chupacabra tubeless-ready tires, and Shimano Deore XT components. It comes with a KS eThirty Integra dropper post. 

The hardtail Powerfly build is a bit simpler: The frame geometry is XC-oriented, with 100mm of travel in the fork, and the rest of the bike has fewer ultra-modern touches—no Knock Block or Boost-width hubs. The 5 and 5 WSD come with a RockShox Recon Silver fork, Shimano Altus and Alivio components, and Shimaon M315 hydraulic disc brakes. The Powerfly 7 uses a RockShox Reba RL fork, a Shimano Deore XT drivetrain, and Shimano M615 hydraulic disc brakes .

The motor on all the bikes in the line is the Bosch Performance CX, which provides 500Wh of torque. It tops out its assist at 20 mph—you can go faster than that, but it’ll be under your own steam. The bike is pedal assist, with no throttle—so you won’t get any power without pedaling. The motor is located in the bottom bracket area and is protected by the Motorguard, a piece of plastic designed to deflect bumps and strikes. The battery attaches to the bike’s downtube, above the motor. There’s no space for a water bottle, so you’ll need to bring a hydration pack. 

Test Ride: I took the Powerfly FS out for two rides in the Swiss Alps. While I’ve ridden plenty of e-bikes on the road, riding the Powerfly was my first experience with a motor-assist on singletrack. The bike uses a head unit on the left side of the bar to control the power and to display speed and battery life. Two up/down buttons on the left side of the unit adjust the power level, and riders have four choices: eco (50 percent assist), tour (120 percent assist), sport (210 percent assist), and turbo (300 percent assist). There’s also a “walk” mode: Riders hold in a button on the bottom of the unit, and it provides a small burst of power to make it easier to push the bike. 

The advantages are obvious: In three hours of riding, we covered 26 miles and 5,000 feet of climbing on singletrack and fire roads. It was the kind of ride that would normally leave my legs feeling heavy for the next few days (if I was even able to complete it at that speed), but the next morning, all I felt was some slight soreness in my upper body from piloting the heavy bike. I was able to explore new trails that I normally would’ve avoided because they were either too steep or contained an unreasonably long climb. There’s no doubt that the Powerfly enables riders to go farther, faster. And there are some really rad experiences to be had—on day two of our testing, we received special permission to ride up a downhill flow trail that runs through the Alps. Berms and bridges were interspersed among steep, smooth descents and bumpy dirt roads that led through cow pastures. And let me tell you: Railing an uphill berm is pretty freaking fun. 

The disadvantages of the bike are clear as well: Huge climbs like the alpine ones we tackled require lots of power—if you’re on a long ride, you’ll be carefully rationing the battery the rest of the time (and, if you’re anything like me, becoming increasingly stressed as you watch the battery drain). The display shows how much battery is left by using bars—you start with five. On a bike like this, a dead battery is a ride-killer. Even when the battery is full, the ride experience is very different from most conventional mountain bikes—it feels heavy and less maneuverable on descents and nailing down timing over logs and rocks is difficult. Plus, there are plenty of new skills to learn—correctly distributing my weight when climbing with so much power is a new experience to me, though those riders with motorcycle experience seemed to have an easier time. 

There were times when the bike’s power made me very apprehensive—most notably, when navigating a series of bridges on the flow trail, and when riding an exposed trail that ran along the side of the Alps. Both of these were situations where I would normally be making small adjustments with the pedals—turning a half-pedal stroke here to balance, or ratcheting the cranks to avoid striking a pedal. Those situations are way tougher when that action could propel the bike more forward than I was expecting. Plus, the bike rewards light, fast pedal strokes—grinding a tough gear results in less power being delivered from the bike. And on sections of trail where the rider needs to stand and level the cranks, the power cuts out, leaving the bike feeling slow and sluggish. 

      RELATED: Specialized Turbo Levo E-Mountain Bike

The bike’s power didn’t feel like it always kicked in equally. At times, a quarter turn of the crank would result in a boost so powerful that you’d be sent into the weeds if you weren’t ready. Other times, I struggled through nearly a full pedal stroke before the motor would help. I talked to Rick Hoak, sales manager with Bosch, about that sensation, which he attributed to variances in gearing and power level: “Due to the smooth support, it’s easy for e-bike riders to migrate towards higher gears. This can pose a problem if the terrain suddenly pitches up where being in a lower gear would provide a quicker, more sporting response than in the highest gear.” It seems like this is something that could be mitigated with more experience on the e-bike. But during my two days of testing, I was still a long way away from figuring it out.  

The buttons that operate the power level are simple, but not necessarily easy to use. They require a firm click to change, and though they’re situated on the handlebar near your hand, they’re not as convenient as something like a shifter. I wanted some of the audible confirmation I get from a shifter to confirm that I hit the right button, and the screen can be tough to see, especially on techy terrain. 

I ran the battery dry during that three-hour ride on the first day of testing. I toggled between the modes pretty extensively to get the feel of all of them, and used plenty of Turbo on the day’s first big climb. When the battery dies, there’s really no warning signal—when climbing the final hill, the screen blinked, then displayed an empty power bar, and all the assist cut out immediately. There’s nothing to do to revive it; toggling down to a lower power mode won’t help. You’re just stuck pedaling a 45-pound bike—and it’s not a pleasant experience. Some sort of power reserve or warning signal would be a good addition to the model. 

The battery life will vary widely, based on conditions like rider weight, terrain, speed, and mode you’re in. For some idea of range, in Turbo mode, the battery should last between 15 to 38 miles, depending on circumstances. In Eco mode, that jumps to 50 to 110 miles; the other two modes fall in between. Batteries weigh 5.5 pounds; you could theoretically carry an extra if you had a big ride planned, but they’re awkwardly shaped, not terribly light, and have hard edges—it would be a tough sell for me to carry in a hydration pack . The battery charges fully in 3.5 hours, and is warrantied to have 60 percent of its original charge capacity after two years or 500 complete charge cycles. 

Of course, the US market for e-mountain bikes like the Powerfly is still relatively untested. I posed some questions to Trek: Who do they see as being the main market? How do they think they’ll be received? The answer: No one is really sure yet. While these bikes can definitely act as a range extender for established cyclists, they could also open up the market for riders who are just getting into the sport. And of course, with the current debate in the US about where exactly people can ride these bikes could affect how popular they become. But if the European market is any indicator (and we’ll find out if it is), these bikes could be poised to take off—and fast. 

The Powerfly will be available from Trek retailers in September. Pricing is as follows:

Trek claims that the current Powerfly lineup has become one of the most popular lines of their bikes in Europe. Now, that electricity is coming state-side. Touting similar benefits as other e-bike manufacturers, the Powerfly line will “allow riders to go farther, ride more often, and tackle more challenging terrain.” By offering both hard tail and full suspension bikes, the Powerfly lineup includes four different models with bikes for both men and women. Relying on the Bosch Performance CX drivetrain, the Powerflies will be cranking out 75Nm of extra torque and four levels of e-assist…

At the top of the line, the Powerfly FS 8 Plus builds a motor into a full suspension platform with 27+ tires and Trek’s ABP and EVO link suspension system. Set at 130mm of travel front and rear, the frame sees many of the same technologies as the new Fuel EX with Boost spacing, the Straight Shot down tube, and Knock Block frame defense steerer tube stop. The full bike will set you back $4,999 which includes a dropper post and 1×11 drivetrain. All of the Powerfly bikes are equipped with the Bosch Intuvia display and controller, Powerpack 500 or 400 Wh battery, and are limited to 20 mph.

The Powerfly 7 drops the price down the $3,999 by removing the rear suspension and adding 29″ wheels and tires. The Alpha aluminum frame adds additional protection for the motor, and is able to accept fenders, racks, and a kickstand. Built around a 100mm travel RockShox Reba RL fork with G2 geometry, the 7 also includes an XT 1×11 drivetrain and Bosch CX drivetrain limited to 20 mph of assist.

The Powerfly 5 will be available in both men’s and women’s models with different frames and gender specific touch points. Both include 100mm RockShox Recon Silver forks, a Shimano Altus/Alivio 1×9 drivetrain, and the Bosch CX motor with Powerpack 400 batteries limited to 20 mph of assist. The entry point for the Powerfly line up, the 5 and 5 WSD will both sell for $2,999.

While the women’s Powerfly will only be available in 15.5 and 17.5″ frames, the rest will include a full size range from 15.5 to 21.5″. Check out Trekbikes.com  for complete spec, or the FAQ below from Trek for more info on their Powerfly line or e-bikes in general.

Powerfly FAQ Isn’t riding a pedal-assist bike cheating? If having more fun, riding farther, riding new places, getting new people into mountain biking is cheating, then yes. Where’s the throttle? Powerfly is a pedal-assist mountain bike. It amplifies the power the rider puts in while pedaling. If the rider isn’t pedaling, the bike is not assisting. It is not self-propelled. Where can I legally ride this bike? Regulations on where eMTB bikes can be ridden legally vary by state and whether the land is federally, state, county or privately owned. Trek and IMBA promote a position that safely guides eMTB users towards trails that won’t be questionable: “E-MTBs are approved for use on trails that allow pedal-assist or motorized vehicles. You are responsible for knowing and complying with all regulations and use laws. If uncertain about trail status, check with local parks management or consult your retailer.“ Where can I learn more about eMTB regulations? People For Bikes has a well-curated list of resources and explanations surrounding eMTB: www.peopleforbikes.org/e-bikes Do eMTB’s have any more impact on trails than traditional mountain bikes? “Not significant.” IMBA conducted a study of Type 1 (low speed pedal assist) mountain bikes, like the Powerfly, and found that “the impacts from Class 1 eMTBs and traditional mountain bicycles were not significantly different, while motorcycles led to much greater soil displacement and erosion.” In short, riding poorly constructed mountain bike trails or riding trails while still wet will have much more impact than eMTB riding. You can find the full study on People For Bike’s e-bike resources. How fast can it go? It’ll go as fast as your legs turn the pedals. However, the pedal assist cuts out at 20mph. Can I ride the bike in the rain or wet conditions? Yes. The Bosch system, including the battery, is weatherproof and will function fine in wet conditions. The motor is further protected from mud and rocks by Trek’s exclusive Motor Armor that also acts as a skid plate over large obstacles. However, none of the Bosch components should ever be submerged in water or cleaned with a high-pressure hose or power washer. How does the Bosch Performance CX Motor differ from other units? The Performance CX motor is designed for the rigors of off-road use with 75Nm torque for enhanced responsiveness and capability on steep or challenging terrain. The drive unit is slightly smaller than other motors, giving it better obstacle clearance. The mid-mount placement of the motor ensures the best weight distribution for balance and control. How long does the battery last? The 500Wh battery has an approximate range of 170km in Eco mode, and 60km in Turbo mode. Actual range will depend on various factors such as terrain type, incline grade, and individual riding style. How long does it take to fully charge the battery? From empty to fully charged will take about 4.5 hours. From empty to 50% charged will take only 2 hours. Does the battery require any special care? The battery should never be opened, as doing so not only voids all warranties, but also poses the risk of uncontrolled thermal reactions. Use only the provided Bosch eBike charger, which is specifically matched to the Bosch battery and has the right software for optimal charging and maintenance of the battery. Using any other charger will void the warranty and also risk malfunctions or reduced lifespan. Lithium-ion batteries have neither memory nor self-discharge effects, so the battery can be partially recharged at any time without affecting the service life. How many power modes are there? The Bosch Performance CX system allows riders customize the amount of power produced by the motor by choosing one of four modes: Eco (50% assist): maximum efficiency for maximum range Tour (120% assist): steady support for long rides Sport (210% assist): powerful support for more aggressive rides Turbo (300% assist): even more power for support up to maximum cadence (120 rpm) or maximum speed (20 miles/hr) for the most aggressive rides Will the display still function when pedal assist isn’t being used? Yes. The Intuvia display units will still offer all on-board computer functions even when the pedal assist modes are inactive. What makes Powerfly FS better than other pedal-assist mountain bikes? Here at Trek, we know how to make great-riding mountain bikes, and Powerfly FS is no exception. These bikes get the same proven frame technology as the rest of our lineup, including ABP, EVO link, Boost148, Mino Link, and our new Straight Shot down tube with Knock Block frame defense for an optimal stiffness-to-weight ratio. All of this adds up to a true mountain bike with the added benefit of pedal assist. Why do some of the bikes have 27.5+ tires? We gave the Powerfly 8 FS premium spec with 27.5 x 2.80” tires mounted to 40mm rims. This setup offers incredible stability and traction, which enables riders to get the maximum benefit from the added torque and power provided by the motor.

Love the included FAQ to dispel some preconceived perceptions of eMTBs. It should help keep this comment section pretty quiet. Time to make the popcorn…

an E-MTB is really disappointing coming from Trek.

I’m planning on buying a new bike next year, the Stash and Fuel EX were on my short list, I’m really going to have to reconsider that now.

You are going to buy a different bike because they built a bike that you don’t want to buy? I guess I won’t buy a bike from any company that builds a gravel bike.

Millhouse you clearly don’t get it. I’m with Frank. I will not support any company that’s putting short term profits in front of the long term stability of mountain biking. Motors on mountain bikes is playing with fire.

No it is not. Stop making up nonsense. eMountain bikes can be used as commuters. Don’t assume the worst of a product or company just because it doesn’t suit your personal preference. You need to learn how to adapt and enjoy/appreciate things for what they really are. That is how I built Microsoft.

@ everything is coming up millhouse Your comment is foolish and you know it. He objects because the company is creating trail bikes that have motors and may cause further strain on future trail access.

I see your logic, Frank…because Trek hasn’t already been building these in other markets for the past few years :/

“As an Elite Level Corporate Member of IMBA, Trek has contributed millions to aid in the development of trail networks throughout the US. Trek is also the Official Supplier to the Subaru/IMBA Trail Care Crew, providing bikes and gear that hold up to the extreme demands of IMBA’s expert trail builders across the country.”

what’s really disappointing is how hideous they look.

Trek’s new mopeds looks pretty cool if you’re into that kind of thing. I’ll stick with mountain biking personally but I have nothing against someone who would rather go mopeding instead or mountain biking. Just keep your moped off non motorized trails and it’s all good!

Haha, so funny there are still haters fearful about closures. Have any of you ever ridden one? eBikes only provide assistance up to 20 MPH. There’s no throttle, just some extra torque with each pedal stroke. That’s it. They WILL NOT make anyone, regardless of skill level, go faster downhill. The only difference will be this: SOME ebike riders will pass you on the climbs. That’s the only thing you have to worry about.

charles you’re naive if you think just because there’s no throttle trail access won’t be threatened. Personally I feel that’s the biggest danger. It’s hard to tell the difference unless you are familiar with bikes. Because you still have to pedal we’ll end up with blanket trail closures. There won’t be wardens checking to see if your bike has a battery pack or hidden motor, we will just see trail access reduced when other user groups complain about someone going fast up hill and being a jerk about it.

Go ride anywhere in CA, or the front range of Colorado and take note of what a circus those trails are these days then get back to me about whether or not throwing mopeds into the mix is no big deal.

The only thing threatening trail access is all the fear and hearsay about the bike shredding trails and going fast everywhere. The rumors cause hysteria, hysteria causes closures. The same thing happened when mountain bikes were first introduced, if you remember.

I’m going to guess you’ve never ridden an eBike. Trust me, ride one and you’ll see. Like I said, all these bikes do is give you a little extra torque for each pedal stroke. Nobody can ride uphill on these things fast enough to “be a jerk about it.” Imagine 20% more torque for each pedal stroke. Not a rocket by any means.

EBikes are not the threat they’re made out to be for more than just their tame performance. Most mountain bikers will never purchase one. That’s because they’re simply impractical for most riders that are reasonably fit. A fit rider on a normal bike can still beat an out of shape rider on an eBike. They’re heavy. They run out of juice. They’re not allowed in competition and they most likely will not ever be. EBikes will most likely be ridden by elderly or physically compromised bikers.

This is the truth about eBikes. Keep on spreading the falsehoods if you want, but remember you’re contributing to the fear and hysteria.

To be fair, criticism hardly seems like hysteria. Some of us are just critical of new product, especially when its entering a market which deals so closely with ‘the tragedy of the commons’ so not unlike other groups under that thumb, they are a bit sensitive to change.

That being said, I have two friends who just don’t mtb, they just prefer not to be sucking wind, and if they do suck wind it’s only during a 30 minute moto where their adrenaline from roosting a 450 overwhelms their immediate desire to not exert the energy required to pedal. I have literally heard them tell me their bodies are not capable of handling the cardio required to keep up on a bike despite recording their h/r while moto and knowing their body is perfectly capable.

Now will this open up mtb to them? If so do they miss the fundamental biological experience which is the virtuous feeling one gets when accomplishing something whos effort seemed to directly relate to the enjoyment achieved? You see. I’m admitting its a self fulfilling ego trip, but if we admit that, maybe we can then admit ebikes have an entirely different problem, unrelated to trail conditions, or ‘cheating’ and directly related to shaping and forming a new market who uses mtb for a different and what the purists may end up claiming is a less psychologically rewarding experience.

J. Your lazy friends who ride 450s will never ride eBikes. That’s because EBikes provide extra torque when pedaling. I repeat, they provide extra torque WHEN PEDALING. They don’t have throttles. You can’t shred on them. You can’t roost. I rode 450’s, 250 two strokes for years, motocross and off-road. No comparison whatsoever. Climbing still takes effort, just slightly less than a normal bike. If you don’t believe me, ride one yourself. So much misinformation out there about these things. As for me, I’d only ever consider owning one if I lost a leg. I don’t need pedal assistance, but some people do.

We know how they work, it’s not impossible to continue the conversation knowing this point. What is being ridden and made today may morph into very different things as technology changes. Some of us are on that end of things, designing and building some real shredders, for private trails, maybe we want to sell them, maybe we don’t want them also ruining our mtb specific trails.

I would rather be fearful of what could happen with trail access than blow it off and end up with fewer places to ride. I certainly wouldn’t say there’s hysteria, If anything the mountain bike community is playing down what could happen.

Hysteria: “exaggerated or uncontrollable emotion or excitement, especially among a group of people”. Provide some proof that these bikes will actually close trails instead of fomenting fear otherwise you are feeding the hysteria. Land managers are people, have you sent an e-mail to ask how they feel about e-bikes or done any research at all to figure out if what you are saying has even a shred of truth? These big companies have compliance departments whose only job is to make sure all product meets the requirements of the country in which they are sold in addition to being active and participating members of IMBA. Until you can provide evidence that these bikes will actually create an issue, I’m going to trust the people who have an active investment in making sure their product is legal to use.

As lazy as most people really are, eBikes make total sense. Think about it, most riders would rather shuttle than climb, and if a chair is available that’s even better as one don’t even have to lift your bike way up into a truck. In 10 years everyone will be zipping along with ebikes. It will start with the riders at the very back of the group ride with the weak / old /fat being welcomed as they will now not hold everyone up so much, then the mid pack riders are going to be jealous of the esisters grabbing open trail with a few mashes in turbo so they get a ebike and within a couple years, the guys in front will be hammering each other with extra boost, then the weak / old/ fat at the back will want to ‘ride’ with the group again so they will get the newest model with more battery and motor efficiency so they can turbo when others are tour assisting, around and around the spending/performance circle we go.

Do you think their is anything to be said regarding the riding experience? Maybe one could claim 10-20lbs of motor significantly changes the experience of mountain biking to such a degree that flying through the woods on heavier bikes may not even be a comparable experience with and without motor.

I know the way I ride and how I ride including the skills acquired to keep off the brakes on x turn, or commit to holding speed through x sweeper are all things associated to the purity of the skill that is mountain biking.

If those skills can be replaced by other means then maybe its just a different and new experience, almost unrelated to mountain biking and potentially with a long term reward for your effort that has slightly less ego filling goodness. I certainly remember my ‘effort boner’ achieved developing my own film in the late 90’s, maybe something along those lines.

The way is the path? This shortcut could never be so rewarding?.

This phenomenon may be more familiar to those who cross train on bicycles and are used to racing moto… I would imagine those people may claim some of the best bits of human power have to do with the minds ability to rationalize risk as it relates to carrying speed which previously to may have never considered possible., but today it saves you from a few pedal strokes…

In that moment, maybe mtb dies a bit if power is injected beyond the riders ability.

“In 10 years everyone will be zipping along with ebikes.”

“The segway is the future of human transport!”

At some point it would be nice to see one of these huge bike companies stand up to the market pressure and not release an eMTB. The list of companies that I wont buy from keeps growing. Too bad this ends up hurting the local shops, but when the trails are gone, maybe the shops will start standing up to the manufactures too. In one of the local shops, there are warnings on the eMTBs that they cannot be riden on the local trails.

Foolcyclist. I agree, I would love to see at least one company just say no. Or even better, at least one media outlet! (deleted) Super disappointed in all the moped coverage on this site. So lame. I’m close to boycotting this site in addition to all companies producing mopeds marketed as mountain bikes.

Why should an entity whose main goal is to make money (like every other f-ing company in America NOT making bikes) make a political stand? For some reason people fool themselves into buying bike companies’ kumbaya stories about making the planet green, granola, patchouli oil, let’s make love and think it applies to all facets of a company. They feel bike companies should be 503(c) entities, in which they forgo profits and give back 100% of any cash in the black to malaria prevention or inner-city soup kitchens.

You should be going after your political representatives to change the laws that ban/don’t ban eBikes or anything else that gets your panties in a bunch.

I don’t see anyone shunning Porsche/Nissan/Toyota/Audi for making car commercials that show their cars being used above the speed limit on mountain roads.

Flatbiller: You’er missing the point. It’s not about making a political point, it’s about staying true to the sport of mountain biking. Motors are not a part of the sport period. I would love to see a company say that and choose to not capitalize on short term profits at the risk of loosing trail access.

If “staying true to the sport” means missing sales opportunities, then that directly conflicts with the most important goal of a corporate entity: making a profit.

“Keepin’ it real” doesn’t pay the bills.

Flatbiller: Staying true to the sport of mountain biking doesn’t matter? By your logic it would be fine to increase the size of a golf hole to make the game easier if that increases profits. Staying true to the skills required to play the sport of golf comes second to profits. Pick any sport for a better analogy if you want, but you get my point.

Motors are not a part of mountain biking period. We all know profits are top priority and that’s the problem! I won’t support any company that isn’t supporting the essence of the sport. Short term profits do seem to be more important than the integrity of mountain biking and that’s pretty lame.

Those are two bad analogies. Mountain bike trail access is already contentious for many areas in the United States which it is already established, let alone for developing areas. I don’t think it’s unreasonable to not purchase from a manufacturer whose products could directly, negatively affect that.

Bike companies are making and marketing e-bikes because their shops and customers are demanding it (remember the companies that chose not to make MTB’s? Me neither…). An E-Mtb is not a moped or a motorcycle. The key difference is not the motor, it’s mass. A rider using one on the same trails as you has ZERO impact on your experience out there. You’ll never notice them.

It is shortsighted to worry that e-bikes will hurt trail access. The trail access we have now is limited not by the nature of our sport, but by the size of our voice. The MTB community isn’t growing in it’s current state. More voices = more access. We should be welcoming this, not shunning it.

I can understand an E-bike for commuters/city people/ and old people that get pedal enough to get where they want to go.

I can’t understand somebody needing a full suspension mountain bike (which assumes aggressive riding in trick situations) needing a battery to help them. This is like a marathon runner using a scooter.

“I can’t understand somebody needing a full suspension mountain bike (which assumes aggressive riding in trick situations)”

How many full-suspension mountain bikes do you think are sold for “trick situations”?

You people crack me up to no end. “Let me rant about something I haven’t tried and probably haven’t really, truly educated myself on.”

Since Trek is readily admitting that riding an eBike is a form of ‘cheating’, are they getting Lance once of these? Just kidding.

Having a sh*tload of NiCad batteries that are toxic little bombs out in the protected wilderness areas is a great idea. If i remember, there have never, ever been problems with rechargeable batteries failing and leaking. Or causing fires.

*shrugs shoulders, shakes head and walks on*

At least there’s approximately a 0% chance ebikes are going to be okayed for trails where I live.

That’s weird. I thought this was a bike website, not a motorcycle website.

Pedal=bike.

Motor=motorcycle.

If you think an eBike is remotely like a motorcycle than I’m going to guess you’ve never ridden an eBike. Have you?

“In order to optimize a chainline with the Bosch system we at Trek have launched a new rear axle standard and because we like to make up all sorts of new ‘standards’ every 2 years to irritate bike mechanics world wide we are now using what’s called B.S. Thru-Axle with a spacing of 178.314. E-bike’s generate more torque so obviously we couldn’t use a hub that already existed because well, E-bike…”

First good eMoped story. Friends came across an elderly gentlemen who had fallen over and was stuck underneath his eMoped on the side of the trail. Friend declared “f*&k this thing is heavy” while lifting it off him. More to come I’m sure.

Trails are already being torn up with hacked ebikes. If you think these motorcycles are not capable of speed, think again. I saw some guys spinning tires, tearing up single track and digging ruts.

Thanks trek for adding to this problem so you can profit.

I live in MTB central (Bay Area/Norcal). Bikes are sold at every shop, almost. I’ve seen a total of ONE in a trail area. It was not on dirt either. It was going to ride on a graded fire road. The rider was 5-8 or so and 300+ lbs. hardly going to threaten trail access as that battery was straining 200 ft from his car. All you Ebike haters need to chill out. Your trail access issues will remain the same as they are the result of the other users hating you. Period. Adding e-bikes to the mix has zero to do with it. FWIW-nothing you do to appease them will stop them hating you. [deleted] No amount of kissing their ass will stop the hate.

Just waiting….

Just waiting until the inevitable first closure then you pro-motor people will have to stfu.

Just waiting…

#ultralongchainstays

Ebike is just a hip name for a moped. These things are just for lazy A$$ that wants access to non motorized trails. Boycott any bicycle company that is willing to jeopardize mountain biking for a profit.

Doesn’t seem to bother the euro market’s trail access… Maybe we can learn something from them. I.e. Chill out, ride what you want, and move over on climbs if you want to stay on non pedal assist rides. Besides, think of all the fat politicians that can now enjoy trail riding with this tech. More people riding means more access needs.

whether we like it or not, ebikes presence will increase at a terrible rate, don’t believe me? Head to EuroBike this month show and get your mind blown. So what will YOU do about it? run the lazy pos off the trail? mini pump in spokes? break their car windshield? tattle on them to the local authorities? Help track down Strava scorchers and turn them in for speeding? Boycotting a company making ebikes will have zero impact on them. The increase in sales to those not wanting to work as hard will easily displace the loss of a few pedalista sales.

Dinger has an interesting point, IF this technology brings more people that are not currently powering up the hills, then maybe more voices at local access meetings will be due to ebikes. This would be a great thing! Something that is true regardless of power, an ass is an ass regardless. If the Euro etwits are accepted by walkers and pedalers, than maybe those eriders are not being asses about it?

I don’t think ebikes hacked or not will have any noticeable impact on the trail, idiots are skidding huge ruts into every turn now, maybe the future ebikes will regen thru braking process and actually skid less? But with increased speeds whenever pedaling and the reduced time between seen and reacted to with other trail users, that will be a real problem. Most riders I pass in opposite directions get a little sketch, add a lot more speed and things could get interesting. This is where cordiality will be tested!

dustytires-what you’re missing the argument is that E-bikers are going to be THE most casual of users. They want to get the farthest from the lot with the least effort and the very nature of the battery systems insure that they won’t get far. The whole thing is a nonstarter. Which has been my argument all along. But the elitist cyclists continue to beat this dead horse and BR gets massive traffic for their advertisers everyrtime they run a PR on a new model. Just look at the comment counts. They typically erase mine as they don’t appreciate the unvarnished truth on this website. But they dwarf most articles.

“They typically erase mine as they don’t appreciate the unvarnished truth on this website.”

But you’re not speaking the truth. E-MTB’s have great range and any rider, casual to pro can ride farther on one than they could on a regular mtb. It’s also not a non-starter. It’s here and it’s growing fast.

You clearly haven’t ridden one. Demos are happening. Go to one and try an e-mtb (off road, not in a parking lot) and perhaps you’ll see it a little differently afterward.

E bikes are here and we all need to deal with that fact. There is literally only one thing to do now, belittle the heck out if anyone (without a disability) you see riding it offroad. Let loose and make them realize what tiny weak quads they have. Point out their prodigious belly, go ahead and assume there is a receding hair line under their helmet. If everyone who ride these bikes off road feels worse about themselves afterwards they are bound to go away eventually and we can all have our sport back.

Michael-You represent everything wrong about bicycling. It is the attitude you espouse in your post why many people hate cyclists and would vote to restrict trail access anytime they have the opportunity. First of all most MTB riders I see and know already fit that description. Frankly ,wouldn’t have the balls to say any of what you are advocating others do as you and them would likely end up on the ground in a pile crying for your mommy and justifiably so. It is no wonder cyclists (mostly roadies at least) are in such low regard where I live, the elitism which spews out of their mouth daily and attitudes such as yours are hard to hide.

Right, here we go again. Co-worker came home from a vacation last week. His trip was to two place in the alps (yep euro talking) he counted like 85 to 90% pedeassist MTBs (thats type 1 pedelacs in the us) en they were all on official mtb tracks. These tracks are mostly sharerd routes with hikers and somethimes horsebackriders… no issues here.

For me personally, I own a steel hardtail 29″, a alu fully also 29″ and a homebrew 29″ hardtail eMTB. When I want to ride a route in the evening on a week day I mostly take the eMTB, because A my knees a basicly gone B after a hard day off labour I cannot do a normal route on just my own power. I run alot into other MTB guys, mostly riding in groups with spandex in the same colors. They fly past othre users of the trails, dogs are scarerd away etc. I relly really dislike that. As always with a non e or eMTB I just put the brakes on say “good evening” etc and 10 out of 10 times I am greeted with a nice gesture. Mostly that I am not trying to overun them or their pets like the other MTB guys on steroids are trying to. I even had some disliked offenses of one guy who tried to run me down when I was on the eMTB. it took a few moments before he realized that it was the same guy who helped him out with a mech problem a few weeks back when I was on the fully in the weekend….

In the Netherlands an eMTB is just a normal bike based on the law, just like in the us where its a type 1 pedelac. I would say, swallow your pride and be nice to each oither regardles if they ride an oldscool 100% manual mtb, an eMTB, ride on an animal or just walke along. These landscapes are not our possesion, we are just visitors trying to enjoy the outdoors, like any other person.

Plain and simple ther wil be no impact on trail acces with a type 1 mtb, it even would have a possitive impact, because more people want to get outside riding.

On my homebrew, I can typically ride 2 hours on an evening. the would be set on eco or tour modus in the forest, that just makes a bit more challenging routes do-able and for the route back home it would be tour/sport just top get home. When I ride with other people they do not have to chase me because I would speed, on a traditional mtb I am usually not the fastest of the pack (knees…) so with the eMTB its just a fun ride keeping up with the guys.

Cheers, I would say, come over and riide… but that would a bridge to far for most.

Bas (yep a Dutchy)

I am showing my age here? Back in the 80’S when mtb where just starting to be main stream like the emtb bikes now… I read the same words that are being written NOW by the HATERS!

By the age of 10, I was on a motorcycle, I just broke to many pedal bikes.. at 25 I had a mtb. Call yourself a purest? Try riding a 8sp on the back 3 up front, toe-clip, steel hard tail 28lb mtb today! not a droper seat post,22lb full suspension, 1-11 gearing..the list just grows! yea right a purest!

Because the body is old and worn out the emtbs have given me new life! I can ride this bike anytime. I can still ride my mtb but I hurt afterwards. Some day you (haters) will be in my shoes.

If you have ridden one? Try one. Check out the Electrical bike expo and go and try them. Look at the people riding bikes. They are older then you, grandma is riding again! and the smiles. E bikes are here to stay!! Instead of telling everyone where they should not be. Tell us where we can ride. They are not going to be ridden on the single track by those who can afford them, they do not have the skill. You learn that at your age. not at 45 plus.

New laws and education are needed….about where and how they can be ridden is important. For those who say the are mopeds have you ridden one? I mean a moped! While at it try a pedal assist ebike also. I have worked in the bike industry for over 30yrs. Have owned and ridden too many bikes!!!!

I can see both sides of your arguments. With that said, this bike is not a moped. There is no petrol or throttle so calling it a moped is very incorrect. The E Bike when property ridden will not tear up trails. Standard MBT bikes tear up trails that is just a given as most like to ride hard and fast, that is the fun of it. If you do not know what you are doing just stay off of the trail and go obtain experience. The e bike allows you to ride much longer and you can explore more trails in a single day than a standard MBT bike. A well built E Bike is not that heavy at all. Take a look at Haibike out of Germany. The company has been around for over 20 plus years and their selection is remarkable. You should try one before you sling objectives when you know nothing about them. Its like anything else. Do your own homework like I have done. I ride both and like having the option of a much longer ride. When riding an E Bike you should totally be aware of everyone around you and not be an a hole to anyone just because you do have an electric motor. As long as you respect other riders, there will be no issues. Lets all just have a great time out their, maintain the trails and be respectful to one another.

CAN WE TALK!

Listen folks, let me just tell you about riding a Class 1: Pedal Assist only electric bike. There’s no letting off while climbing. You have to stay on the pipe and look farther ahead on the trail than a non ebike because you are covering the distance faster. That means you will be moving at the same speed as a non ebike on any dirt that requires skill. Pick your line early, pick your line early, pick your line early. Those of you who use seat post droppers will be using them way more often due to the weight of the bike and the higher center of gravity. If you are climbing and stop, getting started is way more challenging than a non ebike because the motor does not engage instantly, Bosh and Yamaha for sure. The slower you go the more you feel the weight. A 50lb tip over can be a challenge. Down hills are slower because of the weight balance, compression and the speed that a 50 bike can generate. Lifting the ebike for curbs or obstacles will be a challenge for folks that are weak in the upper body. Hike a bike anyone? That’s a challenge if you are tired or slight of body. Don’t forget to monitor your battery, nuff said. When swinging a leg over an electric mountain bike for the first time it will be apparent that this is not just another mountain bike, check your ego at the door. Ebikes have a learning curve, duh. I have yet to explain the skills it takes to ride technical/chunk, single track, switchbacks and any dirt that would be considered at an inter/adv level. But in a word, challenging. Will you be passed by an ebike? Downhill, extremely doubtful. Uphill, possibly if the terrain is non technical and wide enough. Will a beginner purchase an ebike and out skill, climb or downhill you? NO and don’t be silly. Strava abusers, poor trail building, skidiots and the drought to name a few will continue to be headliners for trail degradation. Responsible ebikers will have little to no impact on our trails.

The Hidden Russia

Tomsk has none of the historical pomp and circumstance of Russia's two major tourist destinations, Moscow and St. Petersburg . For the traveler who hankers for something besides glittering churches and postcard-familiar scenery, Tomsk offers something more subdued. Wooden houses, like those out of a favorite Russian fairy tale, line the streets in various stages of repair or renovation. The many universities give the town a learned, serious atmosphere. And the museums are heavy with the gravity of Siberian history. Set in the midst of miles of taiga, Tomsk has a quiet dignity.

Tomsk Attractions and People

The best time to visit Tomsk is in the summer: June, July, or August. The sunny, warm days are perfect for taking walks in Lagerny Sad, the war memorial park that looks over the River Tom. The residential neighborhoods are full of points of interest, and the downtown area is great for shopping and eating. However, even on rainy days, you can find something to do. Not only is there a recently established art museum, but the Tomsk Regional Museum gives an in-depth look at how the peoples of Siberia once lived.

For those who want something special, it's imperative to check out the KGB Memorial Museum. Located in the original Tomsk KGB headquarters, it is a reminder of the terror of the Communist years and the many labor and concentration camps that were set up in the Tomsk region. The holding cells for prisoners also contain their stories of survival; a rotating exhibit honors the art, literature, and lives of those who were brave enough to fight against and tell about their experiences at the hands of the KGB. The museum is the only one like it in the country, and visitors can see Solzhenitsyn's signature in its guestbook.

The wooden houses are a point of pride for the people of Tomsk. Many of the more elaborate ones have become symbols of the city. The windows are bordered with elaborately carved wooden decorations, some in themes depicting birds or dragons. Some of these buildings are still inhabited, which seems a decent metaphor for the way the past in Siberia maintains a symbiont relationship with the present.

The rare Westerner in Tomsk will be met with wariness and curiosity, though seldom hostility. Anyone who shows interest in Tomsk or the Siberian way of life will make friends quickly. Tomichi, the citizens of Tomsk, love to have guests and to share their warm Russian hospitality with foreigners. Their knowledge of their city and of Siberian history can make a stay in this town especially meaningful. You can meet them at the American Center near Tomsk State University, at the central fountain where many Tomichi congregate during the evening, over drinks at one of the many bars, or even on the bus. Any foreigner tends to stand out, but this can be an advantage when trying to make friends.

Eating in Tomsk

One of the most delightful aspects of a Siberian summer is the food. The markets are full of delicious fruits and berries, all of which are at premium pricing for the traveler who is used to paying an arm and a leg for sub-par produce. There is an extensive variety of cheese and other dairy products, free from the processes that often make US diary bland and lacking consistency. At certain times of the week, you can visit stalls that sell meat freshly butchered or fish freshly caught. Be sure to be aware of any old woman by the side of the road with vegetables for sale  - they're almost always home-grown and delicious.

Tomsk is a part of Russia that is unique for the Eastern European traveler. Its small size and community atmosphere, along with its proximity to vast pine forests, make it an escape from the big city Russia that most tourists are familiar with. Fourteen hours by train will take you to a bigger city, Krasnoyarsk, and then you can ride the Trans-Siberian railroad on to Novosibirsk. However, given Tomsk's character and quality, it is unlikely any visitor will be in a hurry to leave.

Russian 3D printed microsatellite Tomsk-TPU-120 successfully launched from Baikonur launch site

Apr 1, 2016 | By Alec

3D printing is heading for space, and not just due to the innovative work of NASA or SpaceX. The Russian-made 3D printed microsatellite Tomsk-TPU-120, a student-made test satellite that will explore the viability of small 3D printed spacecraft, has just been launched into space. Yesterday, on March 31 at 19:24 local time, the cargo space vehicle Progress MS-02 was launched from the Kazakh Baikonur Cosmodrome launch site, and is expected to be docked to the ISS on April 2.

According to all reports, the launch went well. The MS-02 cleanly separated from the third stage of the launch vehicle 8 minutes and 45 seconds after the launch, Russian media reports. It is now on schedule for its rendezvous with the International Space Station, where it will automatically dock into the Zvezda module, under control of the Lead Operational experts of the Russian ISS segment management group, as well as the Russian members of the ISS crew. “The vehicle’s separation from the rocket was normal,” a Roscosmos official said. It is the second launch of a Soyuz-2.1a rocket with space vehicle of the Progress family since the failed launch in April 2015. During the journey to the ISS, several systems will be tested.

But of course this vehicle will deliver a lot more than just a small satellite. Aboard the MS-02 are 2.5 tons of cargo, including fuel components, oxygen, water and gas supplies, as well as scientific and medical equipment, spare parts and private parcels for the crew. It also, of course, carries a new set of food rations, including fresh fruits and vegetables, such as apples, grapefruit, oranges, onions and garlic. “The crew haven’t ordered anything apart from their usual menu,” one official said.

But of course the most remarkable piece of cargo is the 3D printed Tomsk-TPU-120 microsatellite, which we first reported on last month. This is the first time a Russian-made 3D printed satellite will be taken into operation, and will mostly act as a test subject for future aerospace 3D printing applications. The Tomsk-TPU-120 satellite therefore features a number of new materials, and of course a new manufacturing process. Packed with sensors, it will record the temperature fluctuations on board the satellite and track exactly how the batteries, parts and electronics function. All that data is to be sent to earth in real time, enabling scientists to learn more about spacecraft manufacturing and help the students optimize small satellite design. It will even, they say, be used to decide on small spacecraft manufacturing plans for the future.

The satellite is also a truly Russian creation, designed through a collaboration with various Russian institutes and involving twenty students from the Tomsk Polytechnic University, who have been working on this small satellite since 2014. Just 300 x 100 x 100 mm in size, it features two main 3D printed elements: the lightweight plastic container and the ceramic battery packs, revealed Alexey Yakovlev, the director of the High Tech Physics Institute. The battery unit is the world’s first to be made of 3D printed zirconium.

Once successfully aboard the ISS, astronauts will ‘unleash’ it during a spacewalk, after which the satellite will start to orbit at around 400 kilometers. “This is the first 3D printed satellite shell, showing that 3D printing technology has created a breakthrough for manufacturing small satellites, making them more massive and convenient,” its developers said. Its mission is set to last for six months, and if successful, could usher in a new era of 3D printed satellites.
