Instructions

    • 1

      Loosen the back tire of the bike. This can be done using the adjustable wrench. Loosen the nuts in the center of the back wheel just enough so that the wheel will have a little bit of slack from the frame.

    • 2

      Grab the back wheel and pull it as far back on the frame as you can. Try to pull it back until the chain tightens to the desired amount.

    • 3

      Tighten the nuts in the center of the wheel. This will lock the wheel in place, and keep the chain in place.

    • 4

      Grease the chain once it is tightened back up, this will make for a smoother ride, and extend the life of the chain.
