Just after 21:00 Friday night I was riding south to north through London fields. About half way through the park, a bloke came from the right (on foot) and effectively kicked me off my bike- my memory of the whole thing is a little vague but fairly sure he hit the front wheel and I went down. I landed on my back and then my head - totalling a helmet in the process. (see pic).
Aside from being a little shook up and having a sore back/elbow/neck I escaped any major injury. Front wheel was buckled and bars were bent but my bike basically escaped too.
I was helped up by some passers by, by which point the aggressor(s?) had already disappeared. Couple of witnesses saw it and one rang the police but I didn't stick about so not certain it will have been reported.
Don't think it was an attempted mugging as nothing was taken - but otherwise can't find a decent motive to do something so potentially damaging (aside from people being drunk/mad/very anti-cycling)
Thought it would be worth posting here as a heads-up, to see if anyone has experienced anything similar and, of course, for sympathy.
