It looks like it lifted right as it shifted, I don't understand why they would get rid of the wheelie bars after that. It sorta reminds me of Tim Lynch's old car how is acted, although his would just hold a wheelie forever thanks to the wheelie bar.
Wow, did you see the right front wheel fly up into the air? I think they just wanted to take the wheelie bars off to see what would happen. They most likely knew it was going to pull a wheelie. The roll cage did its job though.
