After seeing yet another brutal accident of an ebike yesterday, I suspect regulation is coming, including requiring drivers to be licenced the same way motorcycle operators are, vehicles registered the same way, and liability insurance required.
When school ends, I often see middle and high schoolers riding cheap (and extremely fast) e-bikes through the neighborhood, frequently blowing through stop signs and generally breaking every road rules. So it's just matter of time before it all gets over-regulated.
and by a cheap bike I mean something like these "bikes":
Same here, a local woman was recently impaled by an ebike. I doubt they'll require licenses but they will start banning them on busy bike / pedestrian trails.
