Bikes are the motorcycles that you drive in LightBike 2. They look like a cross between a motorcycle, bicycle, and a car.
To drive your bike in LightBike 2, you tap on the left and right arrows to turn, and use "Jump" and "Boost" to make your bike jump and boost.
Abilities are special things you can do with your bike, and they are either unlocked by winning or purchased with real money.
Bikes come in different colors and you can change the color in the settings menu.
