Tournaments bikes can be used to level up or evolve another bike:
- Level up: A bike is consumed to level up another bike you already own.
- Evolution: A bike is consumed and merged with others to create a new and better bike.
If you see a new bike in your garage, it's probably because some of your bikes were consumed to create the new one.

If you are certain you were logged in through Facebook on Tournaments, please go to the game's Settings > Account > Logout, log in through Facebook on Multiplayer, open Tournaments, and choose to restore your account from Facebook.
