Why you’ll love it

Rail Gen 4 features a pocket in the top tube, so you can easily upgrade to Bosch’s latest System Controller and Mini Remote if you’re craving a cleaner setup

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 to remove the battery without tools, and lets you mount a water bottle cage

Bosch’s smart system gives you all the same power and responsiveness with a Bluetooth-connected LED remote and eBike Flow app that puts even more control and customization at your fingertips

The controller has Walk Assist and an intelligent e-MTB mode that automatically delivers the right amount of power based on your terrain

The frame is extra-stout with a 34.9mm seat tube to accommodate more robust dropper posts, and an oversized head tube that works with burly e-MTB optimized forks for less flex and more precise steering

Removable Integrated Battery
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.

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.

Bosch LED Remote
The Bosch smart system LED remote lets you easily change assist modes, activate walk mode, or turn on optional lights. The bright LEDs are easy to see in any light, and show you your battery level and assist mode at a glance.

Bosch Smart System
Bosch smart system gives you an eMTB that’s more connected than ever. The LED remote connects with Bosch eBike Flow app so you can get ride stats, adjust settings, and perform system updates. Plus, Bluetooth connectivity makes it easy to add a display if you want to make it easier to see your ride data.

Active Braking Pivot
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.

Bosch eBike Flow app
The new eBike Flow app turns your ride into a personalized experience. Use it to customize your motor’s assist behavior, track your ride stats, and integrate your data with apps like Strava and Apple Health. There’s even handy features like navigation and service reminders.

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.
