Pretty much all my crashes are silly:
Slipped on a tree root, which pointed my bike off a small (2m) cliff. I broke my wrist.
Didn't put front wheel in properly, pulled wheel up over a rut, wheel fell off and rolled down the hill. I went down hard on my shoulder and broke my collarbone.
both within the last 3 years. When younger:
Over bars at as the lights went green - I stamped on my SPD, foot slipped off, toes hit the floor and heal was still on the peddle. The bike stopped dead.
Trying to ride with left hand on right grip and right hand on left grip - don't try it.
Group of us on bikes and my brother pulls out to overtake a mate but doesn't look to see me behind him so we both go down.
Riding next to a friend and my OnZa bars end goes under his OnZa Ules grip at 20mph. He rode out of it I lost a lot of skin on my arm.
Riding too close to friend on overgrown single track, don't see a hole, go over bars and smash in teeth, fortunately I had glue on braces at the time which the dentist says held my teeth in but they made a right mess of my lips. I wondered why people in cars were staring at me on the 10mile ride home.
