This Back rack is meant for bikesI thought i can use it on my scooter too, since my scooter seat is straight and not on a slant, it looks funny like its taking off, so anyone looking for a backrack for a scooter this isnt a good choice unless youre seat bar is on a nice slant, otherwise Id say its a great choice for bikers that carry a backpack this is so much easier and it looks nice, get the bag that goes with it and your off.
