A "wheelie" is a maneuver performed on a bicycle or motorcycle where the rider lifts the front wheel off the ground while balancing on the rear wheel. This trick showcases the rider's skill and control over the vehicle. Wheelies can be done for fun, in competitions, or as part of stunts. To perform a wheelie, the rider typically shifts their weight backward and applies power to the pedals or throttle. Proper technique is essential to maintain balance and avoid falling. Wheelies are popular in various sports, including BMX and motocross, and are often seen in extreme sports events.
