Basically riding on the pavement is dangeous to pedestrians. you turn a corner and bump into someone, you fault. you fall off and bump into someone, your fault. someone steps infront of you and you collide, its your fault. Imagine you didnt do trials and then think about what your saying. bikes on pavements are just dangerous, trials the least i supose due to good brakes and control but still. i know its a bitch and i ride on the pavement all the time. but if you get spoken to be polite, explain about how you feel scared riding on the road and just again be polite!, i have never been fined and i rode in the centre of manc 3 times a week for 2 years, and because i was very polite they let me off all the time. At the end of the day trials is always in the wrong unless your riding on the road safely.
