MoshaY 自転車フレーム ロック可能 自転車ボックス 防水 マウントトップ チューブボックス アクセサリー - 決して変形しない/安全/防水/大容量

This thing isn't too big - it's the size of a medium-largeish water bottle. It'll fit keys, a compact manual tire pump, maybe a travel hand sanitizer, and a compact bike multitool. I was so tired of carrying around our bike tools when we locked our bikes up and walked around - this is great because it's harder to steal its contents than a detachable or non-locking/fabric model. I did have to mount it vertically on my partner's cruiser, so getting things in and out is a little annoying because, the way it opens, things just fall out of the front if you don't take great care when opening the front panel, but it's still better than carrying around a large water-bottle's amount of stuff!!! I didn't find setting the lock combination to be difficult at all, nor was installing it very hard. It's like installing a water bottle cage.

I bought this thing twice, so I thought I know a thing or two about it. The first time, I received a package that has the key item (tool used for installation) missing. I requested a replacement and did install the second time around. It's an idea for suitable functionality but poorly designed and implemented. The door/cover of the box fell off during the installation, though it's not too hard to squeeze it back - but that says something about its quality. The worst part is its mechanism to change the security code: you need to extend your finger inside to reach the lever, which is made into a thin piece of metal (think of a blade). I struggled with various cloth/rubber/foam materials so that the process would not be that painful, but at the end, I still wasn't able to set the 3-digit code. It's that ridiculous. After now about 24 hours, my fingertip still feels sore.

Posting this to see if this helps out anybody. It's a known flaw that this 'security' box is not actually very secure, as you can just jiggle the turning knob and able to open the lock without using the correct pass key. The problem is that the lock has WAY too much free play movement on the locking bar holding the door, to the point where you can just brute force the knob open. I was able to fix it using a 1" L bracket I bought at home depot for about a dollar, and glued the piece close to the where the bar swing stops when locked, as shown in the picture; that way the locking bar has a solid metal edge to latch onto and you can no longer force the lock open. Use a strong permanent glue for this project, I personally used epoxy and it worked great! At the end of the day this is still just a plastic box, so don't store anything too valuable in there. Hope this 'fix' helps someone out.

The hinge to open the box is plastic and easily bendable, making the box somewhat difficult to open. Also, the box is supposed to slide shut, but because it is made of plastic and bendable, it slides with difficulty and is hard to lock. Once locked, it does appear to be safe but with a little forced strength, the box can be opened even when locked.

The intention of the product is great but it doesn’t actually fit any of my bikes so it’s going to waste
