Trial Bike Racing Clash

Trial Bike Racing Clash is a stunt bike game with dangerous rides in different zones. You can play in 1 player mode or 2 player mode, and both the mission and skills game modes can be played against a friend as a race to the finish line.

The page makes a point that going faster is not the only thing that matters. Going without crashing counts too. The source does not list keys, so the on-screen instructions show the controls for each player.

It is a good choice for friends who like bike games with a bit of patience in them. Slow down before a tricky section instead of flooring it, since a crash costs more time than a careful run. Another two-player bike game here is Dirt Bike Racing Duel.

How to play

Choose 1 player or 2 player mode.
Pick the mission or skills game mode.
Check the on-screen instructions for the controls.
Race your friend to the finish line without crashing.

Tips

Slow down before tricky sections so you do not crash.
Customise your bike and rider between levels.
Practise in the skills mode before racing a friend.
