Trek Powerfly FS 7 Gen 2 Electric Mountain Bike
The Trek Powerfly FS 7 Electric Mountain Bike is a trail-ready steed that packs a plush suspension set up, top-tier components and a long-range battery for powering onwards over rugged terrain and steep rises. This hard-wearing aluminium bike features a light, compact Bosch Performance CX motor that sustains speed up to 25km/h and assists up to 250w, with a 625 Wh battery that is integrated into the downtube. Remove it, tool-free, when a charge is required - a full top-up takes just under five hours.
A tasty suspension set up comprised of a RockShox 35 Gold RL fork with 120mm of travel and a RockShox SIDLuxe Select+ rear shock with 100mm of travel serve to iron out bumps and soak up shocks for a supremely smooth ride. The upgraded drivetrain utilises high-end Shimano SLX and XT 12-speed components to provide an impressively wide range of gearing options and crisp, snappy shifting, whilst 4-piston hydraulic disc brakes deliver no-nonsense stopping capability in all weather. Finally, the inclusion of a dropper seatpost means the saddle can be lowered on the move so it's out of the way when opening it up on descents.
