Wooden wheel (single wheel) — a hardwood wheel 1-3 inches in the tip of a 1.5-2 m bamboo pole, split and wedged with a wedge to hold it open, with an axle passing through; a crossbar handle at chest height, carried over the shoulder while running and pushing forward.

Use a knife to carve a hardwood or teak piece, 1-3 inches long, into a circle. Smooth the surface with sandpaper. Drill a hole in the center to serve as the wheel axle.

Take a bamboo pole about 1.5-2 meters long and split it down the middle at the lower end for a length of about 1 node. Drive a wedge in so the split end opens wide enough to fit the wheel. Drill holes on both sides of the bamboo and insert an axle through the bamboo holes and the wheel hole.

Drive short bamboo sticks with nails crosswise into a cross shape, positioned at the player's chest level

Rest a bamboo pole on your shoulder, hold the crossbar with your hands, and run pushing a wheel along roads and paths. Some people make the wheel like a train wheel, or attach animal figures that move as the wheel rotates.

The double wheel is made the same way but uses two wheels on a single axle, and has a rope steering handle near the shoulder for steering. Beware of knives and hammers.
