Hey guys, I am Davin, and I am new to the group, I haven't seen anyone asking about this so I'll start. I am wondering what is the best option to create a bike that have self-charging feature. I know regenerative braking works, but the efficiency is super low, if I am not mistaken, it is around 5-8 % return of energy. And I haven't seen any bicycle that can decently translate kinetic energy to electrical energy. Any suggestion?
