No, but this conversation came about because certain condo boards have banned these, which is already punitive and screws over a not small group of people, and a post further upthread said "An ebike ban will happen eventually." This seems fairly credible to me, as the city has already banned e-scooters for no legitimate reason. I am gratified to see the numbers of e-scooters growing every time I find myself in the city, but it is nevertheless the case that this is not sanctioned.
This is not a risk that would be eliminated by banning e-bikes. Buses burn down every now and then too, and did so before there even was electric personal transport.
This is also not a problem that would go away if you banned e-bikes. Regular bikes can also lead to serious overcrowding, all it would take is one nice weekend with pent up demand on the Niagara train.
Nonetheless, we are getting off topic here. I'm not talking about taking them on transit, I'm talking about the city or even individual condo boards banning them. If the transit system bans bikes from itself during rush hour, you have the option to leave your bike at home. Where exactly are you supposed to put it if your condo board bans e-bikes? Or if the whole city does? Suddenly you are up shit creek without a paddle.
