OK this might be a "stoopid" reply.
I had a road bike client once upon a time that fell over EVERY time he tried to get off the bike. I had started him with regular "open" pedals just to be safe because he was a bit tentative on the bike.
He literally came back with all his knees and elbows bleeding after owning the bike for a day and asked us what was wrong with the bike.
I walked outside with him and asked him to ride/stop and dismount. As his baggy running shorts over his tights snagged the saddle....he went down again. "See?"....he exclaimed, "it happens every time!"
