How to Make a Bicycle Saddle Bag

Saddlebags or panniers are an awesome add-on to your bicycle. Not only do they look aesthetically good but they are very functional as well! However, saddlebags can be a bit expensive or some available on the market just won't suit your taste. Why not make your own saddlebags? It's not hard as you think and as long as you have all the materials needed, it will take perhaps just a day or less to make. Follow these steps and let's get started.

1
Find a suitable bag. It's better if you can find something that is weatherproof for durability, but any bag you have will do in a pinch.
- Get a bag with that retro-appeal or euro-look. You could go an old army bag from a military surplus store.
- Visit the nearest thrift shop in town. There are no limits here in what style you want. You can even go for canvas grocery bags.
2
Measure the size of your bag. Make sure to measure the length and width of the bag, as well as the base of the bag.
- Transfer these measurements to a 1/4-inch plywood.
- Cut the wood to the size of your bag.
- You should now have two wood panels, one for the back of the bag and the other for the bottom of the bag.

Obtain two L-brackets
- Attach the back and bottom of the saddlebag using the L-brackets.
- Add wood glue for more strength and allow to dry. You now have a board for your saddlebag.
5
Find something sharp (like a scissor or ice pick) and poke the corners. The holes should be at least 1 to 1.5 inches (2.5 to 3.8 cm) away from the corners.
- Get a large screwdriver to make the holes bigger.
- These 4 holes will be use to join the wooden board to your bag.
6
Obtain two set of U-bolts. They should be about ¹⁄₄ inch (0.6 cm) in size, depending on the size of the frame of your bike. For a test fit, mount the U-bolts on the bike rear rack. Get the measurements of the U-bolt from the rack and apply this to the saddlebag.
- Poke the holes for the U-bolts.
8
Drill the holes for mounting. Using the markings the board got from the sharp object you used to poke the bag as a guide.
- You should have 4 holes for you to attach the board to the saddlebag.
- Drill another set of holes for the U-bolts so you can mount the saddlebag to the bike rear rack.
9
Insert the wooden board once more. Screw 4 ordinary ¼-20 nuts on to the holes you made accordingly.
- Screw the nuts on the 4 corners of the bag, securing together the bag and wooden board.
10
Prepare the rear rack. Get your U-bolt and place them on the rack. It is better you place the saddlebag on you left side of the bike so it won't interfere with any moving part of the bike, like the sprocket.
- Insert the U-bolt from the bike rack to the fabric of the bag.
14
Tuck the bag's straps in and you're ready to go.
- Cleaning is easy- simply loosen the nuts of the U-bolts. You can even detach the bag and carry it when off your bike.
This saddlebag can carry approximately 4 kilos of cargo.
Enjoy your own DIY bicycle pannier.
