It also says that "30mph NO PEDALLING required". I thought they had to require some pedalling.
I do have a problem with one of these bikes on my commute, that is ridden as a moped effectively on the cycle path. Pedestrians and other cyclists aren't expecting to be overtaken at those kind of speeds on a cycle path. The guy who I see quite regularly is going to come a cropper or cause someone else to have an accident soon. If you can do those sort of speeds then mix with the cars on the road.
I know that bloke and the bike. He is a liability waiting to seriously hurt or possibly kill someone. I have shouted at him a number of times and once caught up with him and he just gave me a blank look and was gone.
