Haibike HardSeven 6 Electric Mountain Bike 2022
The Haibike HardSeven 6 Electric Mountain Bike is a versatile ride for everyday use across a wide range of cycle trails. Suitable for singletrack, trail centres and more, the durable aluminium frame and powerful Yamaha PW-ST motor system deliver a reliable and exhilarating ride experience. With 250w of power and 70Nm of torque, the motor issues punchy performance on the climbs without feeling unnatural.
A high-capacity, 630Wh battery keeps you focused on the ride rather than your remaining range, and a 120mm Suntour suspension fork damps vibration and takes the sting out of roots, rocks and bumpy trails. The Shimano Deore M4120 groupset offers crisp 10-speed shifting, and Tektro hydraulic disc brakes provide excellent stopping power, even when it's raining.
