I went along these routes the other day for the first time since the pandemic.
Specifically I'm talking about the route from Blackfriars to the West, i.e. to Westminster.
I was annoyed by a number of people riding ebikes, seemingly quite powerful ones. A quick glimpse online seems to suggest that some ebikes are allowed on cycle ways. No doubt policing the prohibition of the more powerful ones would be quite hard work: no registration plate, and they can get away VERY fast!
But does anyone know what the rules are and who or what actually has responsibility for enforcing whatever rules there may be?
