Is the hardware available to recharge the ebike by pedaling? Yes. Is it possible to recharge by pedaling? No; and the reason is regeneration demands heavy push to pedal which is exhausting. Regeneration only makes sense when you use the kinetic energy of a bike in breaking or descending a downhill which at best it can increase the range by 10%. The idea of regenerative braking doesn’t work well on bikes because unlike cars the mass/aerodynamic loss ratio is too small.
