I built this from a front hub kit, the total was about $500.00. She is disabled and can't ride a regular bike. The price includes 3 12 volt lead acid batteries and a new front tire and tube.
Interesting, it reminds me of something that I would have seen advertised in a Popular Mechanics mag. in the early 60's, except that there were no cordless drills in those days.
A person on a regular bike can go as fast as I can on my e bike, I have had them pass me. It's not having pedal assist, it's trying to make two object occupy the same space that causes accidents.
Men must register, women don't have to though. Sounds unfair to me. Boys were groomed to be ready for the army. We have had more than one comander and cheif that dodged the draft. Now, I spoke about a woman's bike because that is what it was advertised as. You are right, not all men were...
I am glad that your friend wasn't seriously injured. Today I had a few near misses, one guy was looking at his smart phone as he pedaled. A few others came out of a curve on the wrong side of the trail.
I have owned both a Yamaha and a Honda motorcycle, I disliked the smell and the noise. To me the e bike experience is soothing and tranquil, I don't care to go over 16 mph, most times I am happy at 10 mph. I don't care for having anything that looks like it has a gas engine.
I am sure that there will be a market for the e-scooters or e-mopeds. I believe that many of us that ride e-bikes like bikes and have a certain romance with them. There might be a small over lap in the two circles.
