Dirt Bike 3D Stunt City is the sequel to Dirt Bike 3D. Prove your skills as a stunt bike rider in the urban districts of the city, without falling off your bike! Some advice from us would be to make sure you use your jumping ability often, it can help you cross large gaps, and sometimes free you from tight spots!
Move the biker with the arrow keys, jump with Space and press R to restart.
