Question: I have a Xena xx15 wheel lock that won't shut off no matter what you do when it is off the bike.
Document: Was needing a solid lock to augment my bikes electronic security system. Visually its hard for someone to detect the Xena as it blends in with the disc. The disc easily fit the front or rear disc. I prefer the rear disc installment to help with the concealment. The Xena lock is VERY LOUD...and is sensitive if someone should sit on your bike. However, I can access my side cases, tank bag, even put my bike cover on or off with affecting the alarm.
You need to hold the lock steady with one hand while you lock it with the other hand. I then lightly moved the handle bars and the lock worked perfectly. My bike is a Piaggio BV350 scooter. My last bike - Piaggio BV250 was stolen. I now have an XX14 on the front, an X2 disc lock on the rear disc and a Kryptonite legend chain securing the rear wheel to a steel pole.
First of all this is a rather expensive disc lock/alarm. People all over the web talk about how great this thing is which is why I purchased it, but I find it to be an overall poor product.The Xena XX14 alarm is well built there is no doubt about that, the problem is the alarm and useability of the lock itself.When placing the lock on your disc break you must insert the key and turn  it until the pin aligns correctly so that it can be closed.
In trying to make my bike less attractive to thieves, I decided on combining this with a paging alarm. It is extremely loud, and should be very, very difficult for a thief to defeat, as a minimum, they would have to take the wheel off the bike (front or rear, depending on how I use it that day).
Xena comes in different size pin. So you are requested to determine the right one that would hold the pin in place to lock.
Trust me, as much as you think you won't forget you put it on the night before...you WILL. So, get the alarm version.This thing blends right in to your wheel, so anybody thinking they're going to take your bike is in for a rude awakening once this thing activates. Only the most dedicated will bother with your machine with something like this installed.
This works and it sure makes me feel secure. The lock mechanism is hard to operate. The shaft sticks sometimes on the caliper and is hard to close. Not to mention the alarm arms itself before you can get it shut as soon as the eye is blocked. Also it is lefty tightey rightey loosey and counter intuitive. It may be really loud when next to it but not all that loud from in the house. This is the best alarm on the market i think but still has flaws.
i checked out and have used several locks for my motorcycle. the xena is the best so far. it's solid, loud and - i hope - effective at deterring thieves. initial battery installation is a little clumsy. but once you get past that, there shouldn't be any problems.
The reason I bought this product, is so I could lock my bike, but not need to worry about leaving the lock on the disk break and riding off. I expect the alarm to act as a reminder to me, as well as a deterrent to a criminal. It just isn't sensitive enough to do that.
I had searched for a disc lock for my bike. There were many offered in the market. However, not many could even come close to what Xena's product profile. Without any hesitation I bought the product. To my knowledge, this is not that motion sensitive. You'll need to shake a bit to trigger the alarm.
Answer: yes
