i've haven't had the chance to ride with paddles yet so i can't really compare the two, but i can tell you that you don't have to have paddles to have fun. the only time you really have troubles is starting off (don't even bother using first gear, or racing) and if you don't get a good enough run at a hill.
well u never no...my dad has always wants to go to things like trike fest and things like that....and there all in sand soo i never no if im gonna ride sand one day
