has anyone ever implemented a regenerative braking generator for a
bike? seems like a good way of using that excess energy that gets
burnt off when i brake, and it won't use precious power when i'm going
uphill/against the wind

my bike and me weigh about 100kg, so even at 5.5m/s (20km/h), the
battery would get a 1500J hit slowing me down to a stop. maybe
smoothing capacitors would be needed
