If it were me....the 650watt dirt bike would probably have the longest life span of usefulness. It goes almost 20mph and has a 220lb rating. (so you can ride it home drunk at night from neighborhood parties!) The quad was fun for my son when he was smaller.
Oh damn
Well my son has a gokart and it just sits
Why?
Bc his ass rather ride the damn lawntractor and pull the trailer it goes on around the damn property
Shit he even put the go kart on the trailer n pulled it around
