          • The new System Controller shows your currently-selected assist level and remaining battery level. Its neatly integrated into the top tube for maximum protection and a sleek look
          • Boschs new smart system gives you all the same power and responsiveness with a new discrete Mini Remote thats streamlined with just the controls you need at your fingertips to toggle through assist levels or change to walk mode
          • Intelligent eMTB and eMTB Lite modes automatically adjust the assist based on your input to give you just the right amount of power for your ride
          • The new 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
          • Treks 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

          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.

          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 Mini Remote

          The compact, ergonomic Mini Remote lets you easily change assist level, activate Walk mode, or turn on optional lights, all without moving your hand off the handlebar. Plus, its wireless and connects with your System Controller via Bluetooth

          Bosch System Controller

          The System Controller gives you a quick overview of your assist mode and battery level without distracting you from the ride. Its integrated into the top tube so its out of the way but still easy to see with LED indicators. It also connects to the eBike Flow app via Bluetooth for accessing ride stats and performing system updates.

          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 motors assist behavior, track your ride stats, and integrate your data with apps like Strava and Apple Health. Theres even handy features like navigation and service reminders.
