Should the training wheels of children's bicycles be the same height?

The auxiliary wheels of children's bicycles are the same height on both sides, and they are all slightly off the ground.

Children's bicycles are one of the main categories of children's bicycles. Children's bicycles include four categories: children's bicycles, strollers, baby walkers, and children's tricycles. When buying a bicycle, consider the age and height of the child, and choose the appropriate size, that is, a bicycle with a saddle height in the range of 435-635mm. When buying a vehicle, pay attention to the size of the hand brake. If the size is too large, the child will not be able to hold the handbrake tightly when braking, and will not be able to stop the car. So it's best to take your children to try it out when shopping. In addition, the braking force shall not be less than 50N. Otherwise, the vehicle will not be able to stop, causing harm to children. Children’s bicycles are also equipped with protective wheels (balance wheels), which can keep the rider in balance, so pay attention to whether they are equipped (one on each side) when purchasing. It is necessary to consider this. The chain cover of children’s bicycles is indispensable. Children’s bicycles with a saddle height equal to or greater than 560mm should be equipped with a chain cover or other protective device to cover the outer surface of the chain and the meshing part of the sprocket. When meshing on the sprocket, the chain cover should extend beyond the outer side of the chain in the diameter direction. If the chain cover is not used but other protective devices are used, the covering range should be extended to the point where the sprocket initially enters the two sides of the chain. Measure at least 25mm along the chain.
