Bosch Performance Line & Purion eBike System
The new 2022 HardSeven 4 eBike features the Bosch Performance G3 crank drive motor, 400Wh PowerTube frame integrated battery and Purion control system. The 250w Performance system outputs 65Nm of torque and peaks at over 500w! It certainly packs a punch, offering up to 300% assistance in turbo mode.
Featuring 4 levels of assistance (and remember you can always turn the power off and ride it as a normal bike) ranging from 40 to 300% assistance, the new eMTB mode allows the user to set off in one assistance mode while allowing the clever Bosch eBike system to determine and deliver the level of assistance required based on user input to allow maximum support where its needed, but reign it in to save battery capacity/range where its not.
The HardNine 4 features the latest 'PowerTube' Bosch 400Wh battery technology for 2022. Now integrated into the frame, Haibike have neatly designed it so it can be charged both on & off the bike.
Sitting on the left of the bars, the 2022 Bosch Purion display is neat & compact. Riders can see important data like speed, distance, battery range & much more, on an easy to navigate LCD screen.
