> electric biking is expanding your reach a few times over. Electric bikes are motorcycles, and I don't want vehicles with the speed and acceleration characteristics of a motorcycle in my bike lane, if you please. postscript: my very concerns for my safety seem to be getting voted down a lot considering that our friend the Dutchman here has given a rather nice reply recognizing the substantive nature of this conflict
So in NL, this is tackled with a tiered classification, in which the lowest tier ( This is not ideal, as the (fast) electric bike is new, also in NL, and people will misanticipate them (which I've experienced first hand). You're right, mixing speeds is a bad idea. This will improve with better infra (wider cycling paths, bike highways) and getting used to this new vehicle. On the other hand, the problem is similar to…
Weight and velocity are also important (potential energy which could cause harm) but acceleration is the right way to sort things into lanes, there can also be an energy constraint for the lane but acceleration is about being able to anticipate the behavior of something so that you can avoid the accident in the first place.
Electric bikes can accelerate fast and the user will also not care as much about stopping (and losing hard won inertia) this could invalidate some expectation and cause an accident.
