And yet, I've fallen onto the bike while failing to reverse it. It was very silly but I was glad to fall on the non-drive crank instead of a chainring. However, I still don't wear leg protection while pushing a bikehmmm.... not very convincing is it? If you walk so close to the chain, the pedal is going to be a bigger problem, and they're on both sides of the bike. And the 'event of a fall' scenario is just plain silly.
