How to Lock a Bike Seat

A constant concern for cyclists is the security of their bike when it is parked outdoors. Many bikes have easily detachable parts, such as a wheel or the seat. Ensure that these parts will not be stolen with proper bike locking methods. If you have a bike with a removable seat and you do not want to have to take off the seat and carry it around every time you leave your bike unattended, lock the seat instead. There are two available methods for locking a bike seat. One includes permanently securing your bike seat with a length of bike chain and the other uses a cable lock in conjunction with a U-lock.

Instructions

  1. Locking a Bike Seat with a Bike Chain

    • 1

      Adjust a spare section of bike chain to fit through the bars on the underside of the seat and around the nearest section of bike frame. The length should create a fairly taut fit so that the chain does not rattle or clank while you are riding. Use a chain pin tool to remove or add rivets and links to adjust the length.

    • 2

      Loop the chain around the seat bars and frame.

    • 3

      Insert a rivet to connect the two ends of the chain and to create a single loop. Use the chain pin tool to lock the rivet in place and secure the chain and seat.

    Locking A Bike Seat with a Cable Lock

    • 4

      Unlock and remove the crossbar from the U-lock.

    • 5

      Slide the loop on one end of the cable onto the U-lock.

    • 6

      Thread the other end of the cable through the bars on the underside of the seat and slide the loop on that end of the cable onto the U-lock.

    • 7

      Position the U-lock in place around the bike frame and bike stand.

    • 8

      Reattach and lock the crossbar onto the U-lock. This will simultaneously lock in the ends of the cable, thereby keeping your seat secure.
