It's a cheap product and you get what you pay for. My biggest grief with these is they keep describing as an automatic gearbox and it is not. It has one gear only and has a centrifugal clutch for that gear. Great for small kids due to lack of speed. It can rev fast but the vibrations form engine and drive will make you want to slow down before it breaks. Saying that if it is used correctly it will last. Not for teenage boys !!
Engines will out last everything
One gear
