I was riding on the bike path at the beach and it goes through a parking structure for a bit. A young woman was riding behind me no handed and she reached up to touch the structure and down she went. Lucky she wasn't hurt.
I sold a Landshark bike to a friend and we were finishing a ride and he was no handed through a parking lot and ran into a large potted plant buckling the top and down tubes on the frame. Since it was lugged and brazed Landshark was able to replace those tubes.
I don't have the skill or desire to ride with my hands off the bar for more than a few seconds. I also don't have the "wheelie gene".
