The best I've ever gotten the bikes in CP77 to wheelie. Sadly, to do a wheelie of this length or longer, it's necessary to break the gearing.
As in.. only one gear. 0-200 in first.

Riding like that means you can  ride down the road wheelieing, but anything other than that sucks, so..

A compromised version of Driver NC with shorter wheelies than the video will be out tomorrow. Probably.
