Trek Rail 5 500wh Electric Mountain Bike 2022
With its 500Wh battery and powerful Bosch motor, the Trek Rail 5 500wh Electric Mountain Bike is your ideal partner in crime for shredding singletrack and scoring laps on all your favourite trails. Featuring 150mm of supple rear suspension and a burly 160m fork, it irons out rough terrain to put you in control, and the 85Nm of torque and 250w of power from the Performance Line CX motor boosts your abilities on the trail with a maximum assisted speed of 15.5 mph / 25 km/h. The specification is durable and includes four-piston brakes to enhance your stopping power, as well as a 12-speed Shimano Deore drivetrain to conquer any grade of climb.
RockShox air suspension provides supple performance on the trail, encouraging traction for rapid cornering and a confident ride character. The 29” wheels are tubeless-ready and come equipped with 2.6” wide Bontrager XR4 tyres to boost grip on loose terrain. A dropper post allows your standover to be increased at the push of a button, improving your positioning on technical descents.
