This did NOT affect the stability of the bike. So gyroscopic stability is not the important factor in bike riding. The balance must be a dynamic effect. The trouble with physics and real life examples is that the obvious, neat explainations hardly ever work. Peter Moore moore@Berkeley ..!ucbvax!moore
