A long while ago I was riding down a steep ramp with my cousin's really small bike, while he was on a bigger newer one. So I'm going down the ramp with him, and we make it down alive (hey we were kids we were kinda scared), and I look at him and give him a thubs up (he was pretty far away from me by this time), he turns and goes down the street. While I look at him I'm still going straight, I hit the curb, and get launched into the air (still on my bike going really fast), and then I crash into a light post. After I shake all the scare off, I realise what happened, and the front of the bike wheel has turned into 90 degree angle. Thankfully I didn't get hurt, but it was a pretty scary experience. (note I was going extremely fast)
