A new kind of bicycle racing game is here where you can drive different bicycles in the city and prove that you are the best bicycle rider. In this game, the objective is to collect all of the rings on the road and pass the checkpoints to reach the finish line. Along the way, you will have to deal with different obstacles like roadblocks and crashes. 

The gameplay is simple. Drive through the different streets and roads in the city and collect the rings. Once you have collected all of the rings, you will be able to pass the checkpoints and win the race. The more you ride your bicycle, the more experience you will get.
