BMW’s i division is shifting gears a bit, moving away from their traditional projects and venturing into the world of 2-wheeled automobiles with the advent of the HNF Heisenberg XF1 mountain e-bike.
The real innovation behind the project is BMW’s drive unit swing arm. Typically mounted to the main frame, this particular one floats freely, eliminating the need for a chain tensioner. This in turn not only improves acceleration, but also handling as well – two things we can never get enough of. This 4-joint drive unit is equipped with mid-motor and axle load distribution, along with a stiffer frame, a no maintenance belt drive, and that pesky problematic pedal recoil has been completely removed. This is an electric bike we can’t wait to see more of. [Purchase]
