Kids electric dirt bike. Not a cheap razor style, this one actually has front and rear suspension, disc brakes, real knobby off road tires, 3 speed selection, and real dirt bike look and feel.
The charger that came with it immediately failed, so bike has been re-wired to utilize a USA Deltrans battery charger. This bike is also unique in the ability to simply change out the battery configuration for different power levels and speed. As is the factory 3 speed selection works great and battery changes would only enhance what is already there. Bike comes with extras.
