Police tickets

Effectively banning someone from cycling even for a few moments is not allowed. If you have committed some offence then the policeman should be specific about what it is and either caution you or charge you or let you go (with maybe a little warning) but to ban you from cycling today is beyond his power. I would either ignore him, or take his number and report him. Well out of order, he was.
You cannot be banned from cycling.

Cobblers. There'll be something, public order offence of whatever.

You can be told by the police to turn music down or off, you can be told to stop shouting, you can be told to stop riding up and down the road like a twat.
