Haibike HardSeven 7 Electric Mountain Bike 2022
Accessible and fun to ride, the Haibike HardSeven 7 Electric Mountain Bike is an excellent choice for singletrack, with its high-quality build kit and powerful Yamaha motor system delivering an exhilarating experience on the trail. Neatly integrated into the frame, the 630Wh Yamaha InTube battery provides lasting performance for all-day riding and powers the 250w/70Nm Yamaha PW-ST motor. A range of assistance levels are available to help you balance range and power, and the Yamaha Side Switch display shows key data metrics such as the remaining battery and speed.
The Shimano MT410 brakes feature 180mm rotors to boost their power, providing ample bite for confident descending. A RockShox 35 Silver fork takes the sting out of rocks, roots and other obstacles, offering 120mm of suspension travel to iron out the trail. A 12-speed Shimano Deore/SLX drivetrain provides an extensive range of gears, and the 2.6” width of the WTB tyres issues ample traction on loose surfaces.
