The gameplay in Wheelie is straightforward: use the keyboard controls to steer your bike left or right, accelerate with the up arrow key, and brake with the down arrow key. The game features a unique "wheelie" mechanic, where if you hold down the acceleration key for too long, your character will start to wheelie, giving you an extra speed boost. However, if you're not careful, you'll lose control and fall off your bike, ending your lap.
