Do you like riding a mountain bike? Biking Extreme 3D offers you a chance to ride a mountain bike and challenge multiplayer mountain racing tracks. It doesn't matter when you crash any other riders on the track, they will be crashed into the sky. But please always keep a safe distance between your vehicle and obstacles like trees and rocks. Or else, you will lose the game directly. The coins you won are used to upgrade your bike. Don't forget to try another 5 characters!
