## Questions & Answers

**Q: Is there any option for a holder with a longer strap.  The strap does not fit around my very large tube?**
A: I’ve bought 2 of these for my bikes; and while I’m not aware that the product comes with a longer strap, I cannot imagine that you cannot fine an attachment position. Have you tried the seat post? Or, perhaps, the handlebar?  This is a good product and I’d suggest you look for a place to store it. It should fit in an under seat bag.

**Q: Installation help**
A: The manual is upload on product detail page, you can download now

**Q: Is the device easy to steal off the bike when not being used to lock up the bike ?**
A: It latches to the mount. It does not lock on the mount. Pressing the gray button unlatches it.
So, yes, the lock could be stolen off the mount.
I will not walk away from my bike with it hanging on the mount.
I will either use this lock to secure my bike, or if I use one of my other locks, I will detach this one and carry it with me.

**Q: can i use 2 locks together to make it longer ?**
A: Yes, it is available to connect 2 locks to makes it longer.
