*my suggestion fer keepin yer seat and yer wheel is to buy a cable bike lock, loop it thru yer fork/wheel like you would a b*ke, then wrap it around yer frame until you reach the seat(loop in enough times so that you have just enough cable left to get one final loop around the seat) then, loop it around yer seat. not a completely failsafe way of locking yer unicycle, but the best that i can think of. *
