im going to be riding in sand like the dunes and maybe a little bit of pavement so i wanted to know what is better for that , an ATV or a dirt bike? also im 13
The only good thing about sand on a bike is that you don't get
as hurt when you go down, ... and you will go down.
It makes a miserable, unstable riding surface.
Unless you're very experienced riding a bike on sand
go for the four wheeler.
