I fell off at traffic lights when I put my foot down and my sole just kept on slipping on the ice. Having short legs I just couldn’t do much about it. At least the red face meant I stayed a bit warmer than usual under the helmet. The bike was fine but no-one came to help, they just sat in their warm cars until I picked up (read dragged!) the bike out of the way. Now it’s always 2 feet on the floor in wet or icy conditions.
