It is normally found in the better-quality quads and scooters on the market and is classed as a mid-range combination. The low range (usually in the cheap kiddie carts) unit is generally a Johnson or Mabuchi 550 motor hooked together to a plastic toy gearbox (pretty poor quality). Most people use this 250W motor as a starting block for building their own carts, warbot, Segways, etc. It’s suitable for kids up to about 5-7 years old (after that they may be getting a little heavy, and any younger and you won’t be able to catch the kids). These use a common mounting block which makes the replacement of a worn or broken motor a painless swap over. They are quite powerful for their small size and extremely reliable.
