favorite_borderWhy you'll love it
- 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 – even on full suspension e-MTBs
- For e-MTB, full suspension is a game-changer: it soaks up rugged terrain, so you can ride the Bosch pedal-assist system to its full potential
- It's equipped with an external charging port for easy charging on or off the bike
- It rides like a mountain bike because it is one: it has the same frame and suspension tech that we've refined in our decades-long trail heritage
- The Purion controller has Walk Assist and an intelligent eMTB mode that automatically delivers the right amount of power based on your terrain
Features
Bosch Performance Line CX
Bosch's Performance Line CX motor is made specifically for off-road use with more torque and power for better acceleration. The intelligent eMTB mode automatically adjusts the amount of assist to match the terrain. It's a set-and-forget mode that delivers just the right amount of power. You get optimum control, traction and battery life so you can focus on enjoying the ride.
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.
Trek's Straight Shot frame design optimises the stiffness-to-weight ratio for a more responsive ride. You'll be able to push harder and stay more planted on your line when the going gets rough.
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.
