In real life, you can't ride your bike underwater, but in Underwater Bicycle Racing you can. You have a brand new bike and an oxygen tank on your back. Go exploring the underwater depths. There are trails with dangerous turns, so try not to fall down.
Collect bonuses in the game
There are beautiful underwater landscapes around, cute fish, but you have no time to admire these beauties. Any wrong move will prove fatal. Along the way you can collect pearls and get points. Also, do not forget that the oxygen supply is not iron. Try to refill the cylinder as quickly as possible, otherwise you will suffocate. At some point you can be attacked by a shark, so you'll have to go as fast as your bike can go. How fast can you go?
