For decades, radio-controlled cars have been a popular toy, but their motorcycle counterparts have been lagging behind due to balance problems and impaired flexibility. At the same time, a small toy motorcycle can be fascinating in action. [brettt3] Built some of his own designs, it looks like It is very fun to play.
Using Ducati Draxter and Suzuki GSX-RR as models, the 3D printed car body does a good job of imitating their full-size counterparts. Apply a coat of paint and some finer touch, these may definitely be delicate, but they look great in bare plastic. Bicycles use belt drives to transfer power from the motors in the body to the rear wheels. To keep them upright, the weighted front wheels are used as stable passive gyroscopes.

There is even a tiny micro servo system on the head that allows the rider to rotate as you expect and observe the direction of movement.
Those who wish to recreate these designs at home can use files. Or, learn more about gyro stabilization design to learn more about how it works. Video after the break.
