Introduction: A Stronger Mini-u Bike Holder
Here is my first instructables.
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
The original u-bike holder does not fit into my frame and it is impossible to tighten it around the seat post.
Step 2: Looking for Replacement
I found an evacuation pipe. The mini-U fits into it perfectly. I cutted the exact length of the orange part of the mini-U.
Step 3: Let's Transform the Pipe
I've made 3 consecutives adjustements, in order to install the pipe under the saddle, with cable tie.
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
God bless the inventor of cable ties. What wonderfull things I can do with it !
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
First, I put the straight part into the pipe.
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
I hope you enjoyed my little bidouille (it means hack in french !)
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.

This is great solution and just what I was looking for. Unfortunately, my Ulock is tapered and larger than normal. It doesn't really fit a pvc pipe. This got me thinking... Do you really need the pipe? Locking it between the straps would keep it secure. It might rattle from not being a tight enough fit between lock and straps.Thoughts?

Hi Robbie, I didn't tried without the pipe, it could be tricky to insert the Ulock body without the pipe, in my opinion. Unfortunately, the lock and the bike are gone, I broke the bike frame and actually, I'm locking my new bike with an ABUS folding lock (not such strong as the Ulock, but very compact and well deisgned).

Great idea. The big name U Lock manufacturers all get it wrong with their mountings but yours is ideal. Get the drilled hole right size and avoid any movement. In my case i had to add a bit of sheet rubber inside the plastic pipe as I couldn't get the exact size for my lock.
Thanks Martee!!!

very nice, instead of plastic wraps, you can use metal clamps, like the ones used in car radiator hoses, the ones with the screw used to tighten (worm).

That's a great idea! I've been carrying mine in my bag, since the holder the u-lock came with gets in my way, but I'll have to see if this will fit my bike.
