Your task in this bike racing game is to ride your bike through tonnes of stunt races as you peddle through 26 tracks using up to 20 bikes. There there are also 70 achievements to unlock.
Use the WASD or ARROW KEYS to control the bike, use "X" KEY or SPACEBAR to bunny hop, "B" KEY to use your horn (if you have one). Have fun!
