I recently purchased a mini-u bike lock, very handy, compact, but supplied with a poor holder.
I decided to replace this bike holder. Here is the result.
Step 1: The original one
Step 2: Looking for replacement
Step 3: Let's transform the pipe
The first one, I cutted the half extremity of the pipe.
Then , I drilled a hole.
And then, at the opposite of the hole, I've made a little notch. The cable tie will fit into this notch. The pipe won't slip off the cable tie.
Step 4: The amazing cable ties
I used two huge cable ties, a specific tool is needed to tighten cable ties (by hand it' impossible !)
Step 5: Installing the mini-U lock
Then I install the U part.
Thanks to the specific saddle shape, I'm able to lock the mini-U with its key ( Not so many room).
Step 6: Conclusion
Sorry for my english, I try every day to speak better and better (it's so difficult).
I think it's possible to use a longer pipe, when the saddle has got a different shape.
