The Free Drive System Is A New Pedal-By-Wire E-Bike System via insideevs.com
The concept of drive-by-wire has taken over the automotive and motorcycle worlds in the last decade. The idea that there need not be a mechanical connection between the throttle and engine allowed the introduction of cutting-edge technology that enabled the fine-tuning of power delivery and throttle response.
I'm sure those of you who ride e-bikes have entertained the notion of a pedal-by-wire machine—one wherein the two-wheeler would no longer require a chain or drive belt. Well, it turns out that this could soon become a reality, as two German companies, Schaeffler and Heinzmann, have teamed up to make this a reality. In fact, the Free Drive system, as it's called, is now entering production.does an excellent job of highlighting the parallels between e-bikes and hybrid vehicles.
The way the Free Drive system works is with a power generator mounted within the bottom bracket. Sensors and controllers turn your legs' kinetic energy into electricity which then powers the motor on the back wheel. The concept is similar in nature to those flashlights you need to shake in order to build up enough electrical charge to power the bulb.
Outside the world of cargo bikes, however, I'm not exactly certain that a system like this would be as effective. As a cyclist and e-bike user, I have the tendency to ride further than what my e-bike can handle. So yes, there have been multiple occasions wherein I've pedaled home with a dead battery. As such, the Free Drive system would certainly instill a whole new level of range anxiety in me—but hey, that's just me.
