Description
Trek's Powerfly FS 7 Gen 3 is a full-suspension electric mountain bike that's highly capable on the trails. The durable aluminium frame and RockShox 35 Gold RL fork incorporate plush suspension and provide 100/120mm of bump-absorbing travel up front and 100mm to the back. With a Bosch electric drive system, you can make the most of the descents, with pedalling assistance up to 15.5mph/25kph helping you back up to the top of the trails each time. The battery and motor are neatly integrated into the frame, while the Bluetooth LED remote and Kiox display can be paired with the eBike Flow app, for activity tracking, navigation and customisation.
A Shimano XT-mix 12-speed drivetrain creates a smooth, precise shifting experience across the wide-ranging cassette. SRAM hydraulic disc brakes offer confidence-inspiring stopping power in wet and dry conditions. Frame-size-specific wheels - 27.5" on the smaller sizes and 29" on the bigger bikes, create a similar ride feel across the range, and the strong Bontrager Comp 30 wheels are tubeless-ready and fitted with XR4 Team Issue tyres for incredible traction. A dropper post allows you to move the saddle out of the way as and when required, for more control on steep drops and descents.
