i'd say it depends on the people and the terrain that's for sure! the guy that bought mine was a middle-aged guy, business owner and came with his 3 boys. he came at 9:30 at night to look at it (i knew he was real interested because he didn't want someone else coming the next day to possibly buy it) someone that interested, i'd let them ride it...especially because it was in a big open area. i'd be pretty nervous letting people ride it around cars, trees, etc.
BUT let's say two 17 year old buddies showing up together looking for a free joy ride...don't think so...
