Nitrobike does its best to provide a two-wheeled imitation of Wii launch title Excite Truck -- which isn't altogether odd, considering that developer Left Field Productions crafted the well-regarded Excitebike 64 back in 2000. Since then, the team has dabbled in the biking genre with MTX Mototrax and Wii and PSP's widely panned Dave Mirra's BMX Challenge. Nitrobike, however, marks a definite shift to even more high-flying antics and arcade-style racing. 4/10
