Good luck enforcing that. Delivery riders won't just poof out of existence in a cloud of smoke.
Yeah:
As to who will enforce the ban, Myers said that has not yet been decided. Instead, the TTC says it will focus on public education.
“I know we already have trouble enforcing the bike ban during rush hour, so this will be another layer on top of that,” the chair said, referring to the agency’s bylaw prohibiting bikes on TTC vehicles during peak hours.
Mind you garbage variety ebike lithium batteries are a problem. They're large in capacity and because of that can cause significantly worse fires than your typical laptop battery. Just a simple comparison - a typical laptop battery has 6-9 cells (18650). The typical ebike battery starts at 36 and can go as high as 50-60 of the same cells.
Unfortunately until we stop the unregulated drop shipping from China under LETTERSOUP brands on Amazon and such, we won't be able to solve this. Well executed lithium batteries are extremely safe. Chinese manufacturers make many of those. Unfortunately they cost more so that's typically not what's installed on $1000-1500 LETTERSOUP ebikes. The federal government has to come up with some regulation on what's allowed to be imported. Trying to solve this downstream is more difficult and it puts people who don't know any better or can't afford any better at odds with such measures. It shouldn't be on individual people to avoid buying the expensive fire hazards.
