If your young enough to do it then go for it, by young enough I mean that us old f**kers have done it before and have the sore back and shoulders to prove it, you will also find that your arse will get cold before your head as it will be 2 feet above your head, it's fun to ride like that until you get to lights then you look like a dick cos your trying to look cool while scrunched up in the most unnatural position possible. They are easy to fit and can help you get round corners fast but you limit your vision and if I remember right you limit your turning circle as well, one good thing tho is your really near the ground so it's not so far to fall when it all goes wrong.
