Haibike HardNine 5 Electric Mountain Bike 2022
Ideal for those looking to enhance their singletrack adventures or to enter the world of mountain biking, the Haibike HardNine 5 Electric Mountain Bike provides a stellar on-trail experience thanks to its Bosch Performance Line motor system. This bike is capable of all-day adventures and features a high-capacity 500Wh battery, which is sleekly integrated into the frame to grant a clean aesthetic. This bike has an electric assisted speed limit of 15.5 mph / 25 km/h. The low price point belies its performance, with the high-quality Shimano drivetrain providing a wide range of gears to demolish any climb that may come your way.
The frame is constructed from lightweight aluminium and is both stiff and durable to deliver a responsive experience on the trail. An SR Suntour XCM32 fork uses its 120mm of suspension travel to iron out bumps and ruts, instilling comfort and composure when riding off-road. With its wide range of assistance levels and large screen, the Bosch Purion display keeps all the information you need visible. It displays ride metrics such as speed, battery percentage and remaining range, in miles or kilometres, depending on your preference. Tektro hydraulic disc brakes supply ample power for stopping the additional weight of a motor and battery, and the wide WTB Ranger tyres promote grip across a range of surfaces.
