Remember that couple from Texas that pulled off that one stunt last year? Well they were back at it during the 2012 Ride of the Century complete with a stunt that goes all the way across the bridge and does not end until Lilac:

Here is another video of the same two riders doing that stunt from someone else. It is a poor quality video but from a different angle.

KMOV has posted at least one picture wheelies that did happen. That ride itself got major media coverage, as the police did not want a repeat of what happened last year. This year was to be the last such ride, but there are three other major stunt bike rides that do happen in St. Louis during the year.
