Wheelie Bars

Wheelie Bars Wheelie bars, also known as wheelie bars or wheelie control bars, are devices used on some high-performance and specialized vehicles to prevent or control unintended wheelies or "wheelstands" during acceleration. These bars are primarily employed in drag racing and other forms of motorsports where powerful vehicles can generate enough torque to lift their front wheels off the ground during hard launches.
