Actually, one time, I was riding this previous velomobile (type 6), and the front tire blew out. The vehicle did indeed flip (pitch) 360 degrees over forward, and landed back on it's wheels.

In the newer design(type 10), I have moved the seat back a few inches, and lower, so it is less likely to do that.

I feel I'm doing something unique- all the other velomobiles are recumbents. I think I built the only upright velomobile.
