All you have to do is keep your rider from falling and seriously hurting himself. Before starting, you can choose the colour of your bike, your riders outfit, wheel spokes and the background as well. So go ahead, get creative and make it as colourful as possible. Use the up arrow key to accelerate, but use caution as too fast and your rider could suffer a nasty spill. Use the left and right arrow keys to make the rider lean back and forth on the bike to maintain perfect balance.
