Haibike HardNine 6 Electric Mountain Bike 2022

Built for fast, flowing singletrack and a wide range of terrains, the Haibike HardNine 5 Electric Mountain Bike combines a lightweight aluminium frame with a reliable Yamaha PW-ST motor system. With 70Nm of torque and 250w of power, the motor feels strong and sporty on hilly terrain, making short work of even steeper climbs, and the pairing of a 630Wh battery provides long-lasting power to enhance your range. This bike has an electric assisted speed limit of 15.5 mph / 25 km/h.

A 120mm Suntour suspension fork smooths out rough trails, reducing fatigue over longer distances. The Shimano Deore drivetrain is built to last, offering 10-speed performance and excellent reliability. Hydraulic disc brakes boost control whilst descending, and the wide WTB Ranger Comp tyres bite into the trail to amplify traction when riding on loose trails.
