In Cambridge, MA, USA, and nearby communities, bike advocates have made real progress with lanes and paths and general infrastructure. Also the city requires that new builds have a proper bike room. This building was recently gutted and fitted out and this is the bike room today - overloaded, and the building is barely half full... Looks like they will need to find more efficient bike racks!
Meanwhile in a recent commute I was in a queue of 30 bicycles at a light at which about 6-8 cars get through at a time. 10-15 years ago I was one of the few bikes on the roads at any time.
Hats off to the advocates and representatives of the local cities that have made this happen through continuous pressure and work over decades...
I am not interested in purity or commitment to some ideal, I'm interested in practicality. If we're talking about city cycling, an e-bike is just flat out more practical and flexible as a vehicle for more scenarios, uses, landscapes, and body types. But to be clear: I am not trying to convert cyclists to e-bikes, I'm interested in converting drivers out of cars. And to them, an ebike is a much much much easier sell.
I'm also interested in practicality and I disagree that ebikes are flat out superior for many people and locations. That is my point, that many people vastly overestimate the difficultly of cycling.
I don't disagree with you, but it's worth pointing out ebikes' potential as a gateway to cycling in general. My friend got into cycling by ditching his car and getting an ebike. He was originally planning on eventually getting another car, but he's now talking about getting a gravel bike instead. But I don't think he would have been willing to go from his car directly to traditional cycling.
