World's first hydrogen Fuel-cell e-bike - NOT!

the same could be said about recharging your bike with solar panel or braking regeneration.
I guess if you stop the bike at a layby then run your generator then you can avoid this issue.

Yes, you can generate off road like that. Braking regen cannot be illegal though, it's just recovery of the original legal input, not making something new.
