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.
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.
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.
"Indeed the way it manages to balance big-hit compliance while still giving good pop is mighty impressive. Along with its stout chassis, long wheelbase and burly build kit, the Rail is capable of monster trucking its way down some pretty gnarly descents [...] the Bosch Performance CX Line motor is another key component to the Trek Rail’s all-round performance. In our experience, this is the best full-powered motor out there."
Read more"My first thought about the Rail 9.9 is how it resembles a new school American muscle car, with a ton of carbon fiber and lots of digitally integrated sensors, and as always, more power than its predecessor [...] If there was ever a bike that was ready for anything, the new generation of the Trek Rail 9.9 would be it."
Read moreIt 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.
Read more"Rail dominates the descents and flattens the climbs…it’s every bit as potent as the Slash, but with its own built-in uplift."
Read more"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."
Read more"One of the best all-rounders in the test. This tuxedo-looking bike symbolizes class and intention with a big win on battery life."
Read moreGo Rail Gen 4 for minimalist smart system compatibility, Gen 3 for smart system with visible control at the bars, or Gen 2 for a legacy Bosch system that saves your wallet.

Watch the videoBosch 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.
Shimano XT
Shimano XT is the original mountain bike groupset and trusted by generations of mountain bikers around the world. Whatever the trail, wherever you ride, XT is your solution for mountain biking today. Reliable shifting. Superior braking. Intuitive maintenance. XT is the high performance workhorse you can count on.

Tubeless Ready rims and tires make it easy to ditch the tubes so you get better traction, fewer flats, and less weight. You're ready to roll right out of the box with the included TLR rim strips, valves, and sealant.
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.
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.
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 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.
