Bike Stunt Racer is a free online motorcycle physics game with 25 levels across 5 themed worlds. Race through Construction Sites, Mountain Trails, Volcanoes, Ice Worlds, and a Moon Base. Pull off backflips, wheelies, and daring jumps to earn stars and beat your best times.
Control your motorcycle with arrow keys or touch controls. Use the right arrow (or tap the right half of the screen) to accelerate, left arrow to brake, and up/down arrows to lean backward and forward. Launch off ramps, complete full 360-degree backflips for bonus points, and land smoothly to keep your momentum. Each level has checkpoints, and a 3-star rating system based on your completion time.
Launch off a ramp at high speed, then lean backward (Up arrow) while airborne. Complete a full 360-degree rotation before landing on your wheels. Timing and speed are critical for a successful backflip.

They simulate gravity, momentum, friction, and weight transfer. The bike's two wheels and suspension react to terrain, while leaning shifts weight to affect traction and rotation.
