Trek Powerfly FS 4 500 WH Electric Mountain Bike 2021
Take your off-road adventures further with the Trek Powerfly FS 4 500 WH Electric Mountain Bike, a sturdy aluminium steed complete with 250W of assistance at up to 25km/h courtesy of the Bosch Performance CX motor, ideal for providing an extra push on climbs so no route is off-limits. This compact Bosch PowerTube 500 completes a full charge in around four and a half hours and is integrated into the frame for a sleek look, boasting simple, intuitive removal without the need for tools.
A plush suspension set up with 100mm of travel to the rear and 120mm of front suspension means this bike is more than comfortable on rugged terrain, soaking up bumps for a delightfully smooth ride over any roots or rocks the trail may throw at you, and it features a hydraulic lockout which comes in handy to stop any bobbing up climbs. The Shimano Deore 10-speed drivetrain is always ready for some hard-labour, delivering reliable shifting and a range of gears to suit undulating topography, whilst the TranzX dropper seatpost comes in handy to get weight low over the back wheel when sending it downhill. Stopping is stress-free and tackled with precision thanks to the Tektro HD-M275 hydraulic disc brakes, which perform in adverse weather and testing conditions alike.
