Trek PowerFly 4 500WH Electric Mountain Bike 2022

Featuring a burly aluminium frame and reliable components, the Trek Powerfly 4 500WH Electric Mountain Bike is a capable entry-level steed ideal for leisure rides, a commute with a kick and tackling trails. The Bosch Performance CX motor comes into play with 250W for assistance up to a maximum speed of 15.5 mph / 25 km/h, so tough climbs are made that bit more manageable. The Bosch PowerTube 500 watt-hour battery completes a full charge in four and a half hours should a ride be on the cards later in the day. This battery is concealed within the frame to keep it in top condition and maintain a sharp silhouette, and thanks to the RIB (removable Integrated Battery) system can be removed intuitively with no tools required.

The SR Suntour XCM 34 suspension fork with 80mm of travel smooths surfaces whilst remaining responsive, and can be locked out to diminish unnecessary bobbing when riding uphill or on roads. 1x10-speed Shimano Deore components handle shifting duties with reliable precision, providing enough gears to spin over undulating terrain, and Tektro HD-M275 hydraulic disc brakes ensure firm stopping power unaffected by conditions or terrain.
