Imagine having a ride packed with utilitarian features such as a rear rack, mudguards, and lights, straight out of the box. Enhancing both daily commuting and off-road adventures, this bike brings you the best of trekking and urban cycling.

A robust aluminium frame encapsulates a 625 Wh long-range battery, while a formidable Bosch Performance CX motor (250 Wh, 85 Nm) assures sustained speeds of up to 25 km/h. Enjoy seamless control with the Kiox controller, that not only displays ride info but also connects with your Bluetooth® enabled devices and has a theft prevention feature built in.

Comfort and efficiency define this e-MTB, guaranteed to take your biking experience a notch higher with its SR Suntour 120 mm suspension fork and 100mm of rear travel for smooth rides over rough terrains. Also included is a 10-speed Shimano drive train, powerful hydraulic disc brakes, and a practical dropper post.

Benefit from the integrated mudguards, rear boot rack and lights powered by the battery, that make this bike ride-ready from the get-go. The dropper post allows you convenient control over your saddle height, especially beneficial on descents.

Stand out features of the eMTB include a Bosch Performance CX motor with a torque of up to 85 Nm, a removable integrated battery (RIB) that you can re-install in the frame effortlessly, and adventure-ready accessories. With TREK's custom eMTB Lite mode, experience natural-feeling power delivery and longer battery life.

For estimate of how far you can traverse on a single charge, refer to Bosch's range calculator, which factors in variables for this bike model and an average rider.

Embrace the future of biking with Powerfly FS 4 Equipped Gen 2. An embodiment of power, performance, and practicality- all packed into one dynamic ride.
