Happy Wheels is a ragdoll physics-based, browser game created by Jim Bonacci. The game features several playable characters who use different, sometimes atypical vehicles to traverse the game's levels.
Gravity Defied - Trial Racing [GDTR] is a motorcycle trial racing game bringing realistic physics to the mobile platform. The objective of the game is to race as quickly as possibly through the obstacle-ridden courses.
Guts and Glory is the craziest game show on earth, where ordinary people compete in extraordinary challenges of life and death, for glory! The objective is simple: Race to the finish line while everything tries to kill you.
Bike Mania 2 is very much the same as Bike Mania 1 but it has different courses and is a little bit harder to play in my opinion. This is great if you liked Bike Mania 1 because it will give you veterans exactly what you want.
Ultimate Stunt champ is an extreme bike racing game for free. Your task is to ride the bike through the challenging tracks and reach the destination. Collect the stars and perform stunts to make a high-score. A very entertaining bike racing game for gamers.
