Trek Powerfly 5 Electric Mountain Bike 2022
Designed to excel on rolling singletrack, the Trek Powerfly 5 Electric Mountain Bike is a capable and high-value choice to elevate your trail riding experience. Easily removable, the Bosch PowerTube battery is integrated into the downtube through Trek’s super-convenient RIB system and features a high capacity of 625Wh for long-life performance. The Alpha Platinum Aluminium is responsive and durable without sacrificing weight and features Motor Armour to defend the Bosch Performance CX motor system from harm. With 85Nm of torque, the motor system has superior performance with a maximum assisted speed of 15.5 mph / 25 km/h, helping you cruise even the steepest climbs with ease.
A range of Bontrager in-house components are specified, including the cockpit, which oozes quality and features excellent ergonomics. Powerful Shimano four-piston brakes dispatch supreme power for control on loose terrain, and a 12-speed XT/Deore drivetrain delivers crisp reliable shifting.
