I was biking home with my son a couple of days ago. We were going down a steep hill and had to turn sharp at the bottom.
A couple of pieces of gravel through me off course a bit and my bike was heading straight for the curb.
After the crash, my son asked, "Dad, what happened? I just saw you jump off your bike and fall onto the curb" (I DID fall judo style, I am proud to report).
What he saw was exactly what happened. The only way to save the bike from the curb was for me to jump off the bike at great velocity, throw the bike to the side, and for my body to take the full impact of my mass and speed as bike and man crashed into the curb. It was an instinctive move - I didn't have to ask myself "Body or Bike?".
Ah, the happy ending is that I got back on my undamaged bike and rode home. Nothing was bent or damaged.
How about you? Which takes the fall for the benefit of the other; your body or yout bike?
