Racing on the bikes

Today it is necessary to take part in the competition, which will be held in the park, and it will take you driving all the way from start to finish on the bike. You will need to pass a variety of mountains, going up and down on them, so as not to fall or tip over backward on a steep rise. After all, almost all the time of your journey gets off balance and you need to restore it. Otherwise, you will pull out the victory.
