The worst thing about eBikes is that they can let people ride beyond their ability. Just because you can ride at 25+ mph on a mixed use path doesn't mean that you should ride that fast when you're sharing the path with walkers, joggers, and other cyclists on conventional bikes.

On a conventional bike, it takes some training (and thus, skill) before you can ride 25+ mph for any length of time, but you can take an eBike out on your first ride and ride that fast.
