The Dirt Rocket™ MX350 / MX400 are the same model just a different color. Both are scaled-down, electric-powered dirt bikes that have a fun way for younger riders to live out their off-road fantasies. At speeds up to 14 mph (22 kmh), the MX350 / MX400 leaves similar pocket dirt bikes in the dust. Large, knobby pneumatic tires deliver top-notch performance and maximum power transfer so that riders don’t have to stop where the sidewalk ends. The MX350/ MX400 is fully rechargeable and ready to eat dirt hills for breakfast!
