I've been watching this guy for ages. He's great! If you are unfamiliar with graphene batteries/capacitors, EESDs, check out his other videos.
For hopping around the burbs, I could see a use for something like it.
That. Was. Amazing.
Grapheme is cheap and plentiful, yes?
Got a bike path along a river trail to downtown, maybe 1 or 2 hours bike ride.
Been specing out electric battery assist. Maximum battery cell hiding maybe inside hollow tube frame, if possible.
Downside to electric, 120v is slow charging. 220v or 440v is required for quick charge. But if you ride downtown, there are no higher voltage outlets available.
