NASCAR HammerDown

NASCAR HammerDown is the first bicycle to be added into the game. Not motorcycle, but bicycle. Even though it is in the motorcycle class, it requires pedal power to move, making it the slowest vehicle in that class. However, it is one of the only vehicles with the engine from the Dodge Tomahawk (2003) High even though it is a motorcycle, it has a whopping 500 horsepower Dodge Viper V10 engine. It, however, can also be swapped with engines from vehicles in the car class, unlike most motorcycle class cars. It can be swapped with insane engines from the Volkswagen Golf GTI and the Subaru Impreza WRX STI, to the Ferrari 488 GTB, to the SSC Tuatara, making it well over 500 in performance. It is the fastest vehicle around the Ultimate Circuit.
