Haibike HardSeven 5 Electric Mountain Bike 2022
Offering excellent value and superb performance, the Haibike HardSeven 5 Electric Mountain Bike is an equally good choice for first-time riders and existing cyclists seeking their first assisted ride. The lightweight frame is robust, made from a high quality 6061 aluminium, and features a high-capacity 500Wh battery neatly integrated into the down tube. The Bosch Performance Line motor is lauded for its smooth engagement and natural feel, offering a punchy 65Nm of torque and 250w of power.
A 120mm Suntour suspension fork damps vibration and cushions roots, rocks and more, making this model perfect for trail centres and exploring bridleways. Tektro hydraulic disc brakes offer an improved feel over cable operated models of the past, and the Shimano 9-speed drivetrain provides a range of gear ratios to summit even steeper hills.
