This is designed to work with the ABUS Granit X-Plus 54 Mini U-lock, and be mounted on the Boosted Rev electric scooter, which has a 38mm diameter tube.
It may work with other similar sized locks, but I have not tested it with any other ones.
For mounting, as long as the tube you're mounting it on is 38mm±2mm in diameter, this should work, but again, I haven't tested it.
For assembly, I used these racks rubber straps, and M6 panhead machine screws with 80mm long threading.
