What added weight? If there already is an electric motor on the bike you can just use that as a generator during braking or coasting down a hill. That’s what EVs already do.
Electric cars already do this and I’m sure there are some smaller electronic mobility devices that also do regenerative braking. It’s not exactly a new concept.
You could harvest energy from going down hills and braking, but that’s probably not work the weight.

For each second of using regenerative braking, you can accelerate for 0.7 seconds.
But how much do you actually brake when riding a bicycle? That’s completely neglectable (at least for me).
