Mini Bike Builder

Mini Bike Builder is a paid racing game made with AI by @doc9, and it plays right here in your browser.

Build It. Race It. Win It.

Mini Bike Racer puts you in the garage with real aftermarket mini bike parts — engines, carburetors, exhausts, tires, suspension and more. Bolt on upgrades, watch your top speed and power-to-weight change instantly, then hit the track to see if your build actually holds up.

Race three rival bikes over a fast oval circuit. Each rival is built from a different real-parts philosophy, so every race is a real test of your setup. Finish ahead of the pack to earn cash, then reinvest it in faster parts and chase the perfect build.

It's the ultimate "try before you buy" garage — experiment with real upgrades and find the fastest combination before you ever pick up a wrench in real life.
