Because they put other motorcycle riders and pedestrians at risk.. An e-bike is in fact a motor vehicle and should be treated as such. If it darts in front of a motorcycle, they are both ****ed. If it plows into a group of pedestrians at 40km/h, they're all ****ed.. And I've seen'em ride those things on sidewalks, cutting through parks, even inside buildings.
Exactly... I've saw the most amazing stunts. I flip them the bird.. and honk while passing to spook them.. hahaha
