this happened due to lack of concentration, but im glad i didnt injure any one or damage any property...i have had a look underneath it i can only see one bar that is badly bent..so im hoping its just that for now..i scratched along one of the massive curbs then the front wheel must of smashed sideways on the begining of a new curb just after a storm drain while i was trying to turn away...thats wat i think happen anyways..hmmm..
