The concept of drive-by-wire has revolutionized the automotive and motorcycle worlds in the last decade, allowing for the introduction of cutting-edge technology that fine-tunes power delivery and throttle response. Now, this same technology is being applied to electric bicycles, with two German companies, Schaeffler and Heinzmann, teaming up to create the Free Drive system. This system replaces the traditional chain or drive belt with a power generator mounted within the bottom bracket, turning the rider’s kinetic energy into electricity that powers the motor on the back wheel.
The Free Drive system is similar to a parallel hybrid system found in electric vehicles, but without the mechanical link between the rider and the rear wheel. This means that when the bike runs out of juice, no amount of pedaling can get you to your destination, leaving you stranded with a heavy, possibly expensive paperweight. However, you can pedal in place to bring the system back to life, and any excess energy produced from your pedaling effort can be channeled back into the battery.
The Free Drive system is best suited for cargo bikes, whose long wheelbase configuration could make it complicated to run a chain or belt drive. However, for regular bicycles, this system may not be as effective due to the potential for range anxiety. If you run out of juice, you won’t be able to pedal your way home.
Overall, the Free Drive system is an interesting concept that could revolutionize electric bicycles. It could be especially useful for cargo bikes, but for regular bicycles, it may not be as practical due to the potential for range anxiety. What do you think about this new technology? Does it solve a non-existent problem, or is it the future of two-wheeled micro-mobility?
