After some days of experimentation I think I found the perfect DIY holster for U-Locks. Its ideal for bikes with small frames that don't have enough space for a holster, but It works beautifully on every kind and size of frame.
It's easy to make with materials you have in your drawers.
What you are going to need:
- A small piece of a relatively thick branch
- Inner tube
- Old leather belt you don't want (You can use innertube if you don't have one)
- A wire hanger or thick wire
- A hacksaw (or any other type of saw that works for you)
- A drill
- Big zip ties
- Pair of scissors
- Bungee cords you don't need (Or again, if you don't have, use inner tube instead)
Step 1: Cut a Small Piece of the Branch
1. First of all we need to make the base of our holster. This little thing will support almost the whole weight of the heavy U-lock. So, you can find a thick piece of branch – maybe as thick as y your seatpost (I love this material, you can find it anywhere) and cut it to the length of your seatpost’s width (give or take).
Step 2: Make a Curve on the Side of the Wooden Piece
2. Now, using a knife make a curve on the side of the wooden piece to make it seat
nicely on the seatpost (the pic bellow is from a next step but it shows you the cutting).
Step 3: Cut in Half (across) a Piece of an Old Leather Belt
3. Cut in half (across) a piece of an old leather belt long enough to wrap around
the wooden part – PLUS 5 or more so centimetres. Open a hole on each end of it. To make it easier to hook and unhook, make an additional cut on the hole (You can watch the video to see how it works).
Step 4: Make a Hook
upper part of the wooden part. similar to the pic and sketch. Have a look at the close up as well. Cut a piece of a metal hanger or a thick wire and make it go through the hole. Make sure you make a hook at the end like you see at the pic. The curvature of the hook must press the end of the leather strip down securely. The end of the wire should be hammered down.
Step 5: Secure the Base on the Seatpost With Zip Ties
5. We are almost there. Drill two or three holes on the side of the wooden piece. These are the holes that zip ties will go through to secure this little base to your seatpost. So, wrap tightly a piece of inner tube around the seatpost and press against it the wooden base so it wont unfold. Now use two zip ties (or three) to secure it snugly on place.
Step 6: The Bungee Cord
6. Final step. Cut a piece of bungee cord (if you can’t find one, you can use an inner tube) and knot its two ends on the upper ends of the saddle rails. You can use the rest of the belt if you want to make this nicer (I will propably update the post soon with this version). When you finish, make the U part of your lock to go through it so you can hook it on the base underneath it. It should look like the first pic of the article.
