It sounds like your issue isn’t with e-bikes as a whole, but with high-speed electric bikes being ridden irresponsibly.
Most people ride Class 1 (pedal assist) or Class 2 (pedal assist + throttle) e-bikes, both of which are limited to 20 mph. That’s what most parents in my town (including me) use to haul kids around, run errands, and pick up groceries.
The bigger issue is Class 3 e-bikes, which provide pedal assist up to 28 mph. It’s not uncommon to see kids riding them, and I think operating a Class 3 e-bike should require a driver’s license.
Even more concerning are electric dirt bikes, which technically aren’t e-bikes at all. Many are capable of much higher speeds and require a motorcycle license and registration on public roads, but you still see kids fucking riding them.
There needs to be better enforcement by local police, along with more responsibility from parents who ignore or enable this behavior. Our town has actually started confiscated the electric dirt bikes from kids.
