BMW i Patent Powers e-Mountainbike HNF Heisenberg XF1 - CleanTechnica
Consumer technology is going to exist indefinitely, perhaps for as long as the human species exists. At CleanTechnica, we try to feature consumer technologies that help to reduce global warming pollution and other types of pollution. The HNF Heisenberg development team designed the new suspension technology for the XF1 in a very specific way. To ensure consistent spacing of the low-maintenance carbon drive belt between the spindle and the rear hub, the mid-motor, and rear hub are integrated into the drive unit swing arm. The belt runs under tension and perfectly aligned between both toothed belt discs enabling an effortless transfer even high peak loads from the mid-motor…. One of the dynamic and related advantages of the drive unit swing arm is the fact that it functions without recoil from the pedal. Compared with other rear-mounted suspension concepts, which are specifically optimized for muscle-powered drive systems, there is no stiffening of the rear swing arm when the electric motor is providing a high degree of assistance such as during... From the summer, the HNF Heisenberg XF1 will benefit from the following advantages of the BMW i 4-joint drive unit swing arm:. Source: cleantechnica.com
