Do not know anything about the hensim, but by the pictures it looks like they put a bigger frame under a mini quad body. That is pretty common for a lower priced "adult size" Chinese ATV's. You can tell by the tires. They extend past the body on the sides to make it wider.
This is fine, but if you are looking for a true "adult size" take a look at the Vbike leesumm has. The wheels are better inclosed in the fender wells.
Might take a look at this unit at ATVdiscounter.com, Hunter 250 Utility ATV-20.
It is in the same price range and is a full size body like the Vbike and my Marshin which you can take a look at in my profile. They also have some other ATV similar to this as well as some like the Hensim.
Just passing on something that I have noticed.
