30 mph speed limit for bikes?

^ Whilst initially investigating this I came across claims from several of people being nicked for "wanton and furious cycling". I have been threatened with this once by the police after being knocked off my bike by angrycunt the motorist, luckily I had a good witness and angrycunt was the one to get nicked.
Whilst we are on the subject and some seem to be posting what speed they can achieve, I have hit 39.6mph descending North Hill in Danbury on an 81" fixed. Not something I will repeat in a hurry.Scary.

I was charged with cycling furiously and resisting arrest a long time ago. I always though it was specific to Scottish law, apparently not.
