seat lock / bicycle lock

seat lock
seat lock

Bycycle seat requires height adjustment, and is easy to loosen the connection of it for user convenience.

However because of this, the risk of theft has also been increased.

So I suggest a product which is easy to adjust height and very safe from the theft risk.

Seat Lock usually sets a password to prevent theft.

If you need to adjust its height, Set a password, release the connection, set the height of bike and lock again.
