A short ride with a wipe-out

Last Sunday I enjoyed a lovely four second ride with my husband and my son.  Rob was ahead, and so Matthew stood up and hammered to catch him, when his foot slipped off the pedal, hit the pavement and became a solid object for the pedal to dig into.  The physics of this were amazing; that stopped pedal sent the bike (and son) flying over the handle bars, with an impressive landing to follow.  Thankfully he broke no bones, and his surface wounds are all nicely healing. A sober reminder that small events can trigger big crashes!
