How 'bout some YouTube or other video links about eBikes?
Cool is, cool does - other than braking I wish I had built this one:
Nothing high end but well done on modest budget - notice the tall mirrors are a very good idea since the faster speeds you average the more important it is to be aware of what's around you. I know this area in So CA and you probably don't need much braking capacity as flat as it is. Something hilly, different story.
I think that's a Golden Motor front hub...???
