It's right for you if...
You’re looking for a super capable long-travel e-MTB that’s built to conquer techy runs and big drops. You want the light weight and responsive ride of an OCLV Mountain Carbon frame with a high-powered motor to get to more descents faster.
The tech you get
An OCLV Mountain Carbon frame that fully encases a 625Wh battery, a 160mm RockShox Domain fork, 150mm of rear travel with a RockShox Deluxe Select+ shock, a Bosch Performance Line CX 250W motor. A 1x12 Shimano SLX/XT drivetrain, Bontrager Line dropper post, powerful 4-piston brakes for confident descents, and Bontrager Line Comp 30 29er wheels that are already completely tubeless ready, including sealant.
The final word
Rail 9.7 hits the sweet spot of carbon performance and amazing value. It’s spec'd with quality trail-specific parts and a powerful Bosch drive system so you can send it through the rough stuff and motor right back up for another run.

favorite_borderWhy you'll love it
- The Bosch motor gives you plenty of power for tackling steep climbs with the efficiency to keep exploring all day. Rider-friendly features like Walk Assist and eMTB mode help you make the most of every ride
- Made with the same hard-charging frame tech as Remedy, like Mino Link adjustable geometry, a Straight Shot down tube for extra stiffness, and Active Braking Pivot (ABP)
- The full-color Bosch Kiox display is mounted on the top tube so you can see ride data like support level, speed, battery life, and more
- Trek's Removable Integrated Battery (RIB) system looks great and is super user-friendly: it fully hides the battery in the frame for protection, makes it easy remove the battery without tools and lets you mount a water bottle cage
Best in Class winner!
It was a close competition, but not much could match the Rail on every type of terrain. The Bosch system will get you up any trail and the geometry is as close to perfect as we have found for all-around riding.

"Our e-bike of the Year"
"Rail dominates the descents and flattens the climbs…it’s every bit as potent as the Slash, but with its own built-in uplift."

"Sets the bar"
"Whether flowing or technical, it literally glides by the competition like it's on rails while also offering plenty of comfort for long days in the saddle."

Features
Bosch Performance Line CX motor
Bosch Performance Line CX sets the standard for eMTB performance with up to 85Nm of torque and an intelligent eMTB mode with Extended Boost that automatically adjusts the amount of assist based on the terrain.
Custom eMTB Lite mode
Trek eMTBs feature a custom eMTB Lite mode in place of Tour mode. It gives you more natural-feeling power delivery and longer battery life.
RIB is a one-piece battery and cover with a built-in handle that can easily be removed and re-installed in the frame with no tools and no hassle. It’s the most convenient way to remove your battery for transport, security, or just easier charging.
Active Braking Pivot allows our engineers to tune how the suspension reacts to acceleration and braking forces independently. That means you get more confident control when you need it most.
To see how far you can ride your electric mountain bike on a single charge, check out Bosch’s range calculator. We’ve auto-filled the variables for this bike model and the average rider, but you can make adjustments to get your most accurate estimate.

Bosch Kiox display
Bosch Kiox's bright, full-color screen is easy to read in any light conditions and is protected by durable Gorilla Glass. You can view battery life, support level, speed, heart rate, and more. Plus, it seamlessly connects to your phone through the Bosch eBikeConnect app to share ride data, GPS map routes, altitude, cadence, and power output.
Mino Link adjustable geometry
Fine tune head tube angle by 1/2° and BB height by up to 10mm with the simple turn of a nut. Just flip the link to choose between slack or slacker geometry, without negatively affecting suspension performance. A Trek exclusive.

Integrated speed sensor
You've got one less detail to sweat with the integrated speed sensor. The chainstay-mounted sensor stays protected while the custom hub-mounted magnet stays secure—no more error codes from mis-aligned sensors.
Knock Block
Knock Block has your frame's back when things go wrong. It prevents your handlebars from spinning all the way around in a crash, so your hoses won't get yanked, and your controls won't hit the top tube.

Sizing & Tech
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local retailer.
