The simple hose clamp can be a handy tool if you have to dissassemble and reassemble your scooter for transport. If you put the hose clamp on the seat pole at your preferred seat height, you will always get the perfect seat height with no effort. My husband, until we find a permanent solution, takes his scooter to work every week in his Subaru Crosstrek. This helps him immensely!
We picked it up for less than $2 at Home Depot, but you can also purchase it from Amazon.

Every time you put the seat down, it goes exactly where it should. No fuss.
