Description
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. This bike has an electric assisted speed limit of 15.5 mph / 25 km/h.
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.
