Occurred on July 10, 2021 / Chicago, Illinois, USA

: Stunt ride in Chicago, Illinois. As riders were making their way through their route, 1 rider attempted a left-hand drag wheelie. While attempting this his bike "pancaked" on the left side dragging the rider behind it. That bike went into the left lane and connected with another that was already doing a wheelie. 2nd bike flips, lands on the gas tank, and ruptures the tank letting loose most of its gas, and gets ignited by sparks, causing the massive fire. I was told both riders are ok but one suffered a broken arm.
