This cool looking glitch happened to me... and at a good time. I probably would not of made it if it didn't happen.
Anyway, it looks pretty funny. I must of hit the "auto-fold-bike-for-convenient-storage" button.

Nah only the once and purely by accident. I suspect that it is a rare set of circumstances that make is happen.
