Danger riding on the street depends largely on your riding experience. Basically though, the most dangerous bike on the road is the slowest one. I come from a motorcycle background, and imo the laws pretaining to eBikes are insanely dangerous. There should be no law restricting an eBike to less than the normal surface street speed limit. Yeah I know the worry worts are afraid of fast eBikes racing on city trails with padestrians, but from my experience that's seldom a problem, and there's other ways to deal with it than assuming everyone riding a eBike capable of traffic speed is not able to restrain themselves from trying to break the sound barrier on a trail. One of the best new trends I''m seeing in eBikes is manufacturers are beginning to ignore these stupid dangerous laws by offering faster bikes, and I think that will make eBikes safer overall.
