Crypto Bike Riders is a 3D racing videogame based on the Blockchain NFT technology, it is inspired on popular GP racing games like MotoGP and Motocross Madness adding cool extra features like the possibility to own and customize your bikes and earn $CBRD tokens while you play the game.

To play the game you need an NFT bike or pit box or both, however this is not a limitation, you also can start playing with a contribution of 5 $CBRD tokens that will be converted to the internal currency: Bike Dollars (B$), then you'll receive a random non-NFT bike and you'll be able to buy the resources to play and earn more B$ and also diamonds (premium currency). All the details about currencies and conversion rates are fully explained on the [tokenomics section](/crypto-bike-riders/token-economy/tokenomics-1.md).
