Nulock Keyless Bluetooth Bike/Motorcycle/Gate Lock IP44 Splash-Proof Cycling Lock with 110db Alarm, 0.38" Diameter 24-inch (2ft) Braided Steel Cable Padlock for Gate(2025 Version)

It's not too often that I'm impressed by new technology since it's moving so quickly, I barely have a chance to notice! But I recently bought this to secure my possessions at the campground. I have tried several ways to secure my very expensive Progressive surge protector and haven't felt comfortable with any of them. Then I found this... Out of the box, I had the concept down in less than three minutes! A new record for a technology product! It came with a handy dandy little screwdriver to remove the battery cover and even included RAYOVAC batteries! The cable itself is 31" long, and has about a 3/8" thick cable. The alarm has a 110db alarm which is really, really loud! The lock is keyless and operates completely via an app and bluetooth on your cell phone. I was very surprised to see how easy it was to use! Once you install the app, you press the little lock button on the front of the unit and it shows up immediately in the device list. Click on it, change the name and password and you're done! Anytime you want to unlock it, just open the app and click, Unlock! It only takes about three seconds to connect to the app when you first open it after the initial setup. I noticed a few reviewers said they could not connect. If you press the picture of the lock under the bluetooth symbol, it will beep three times and make itself visible to bluetooth immediately. I didn't see this step in the instructions. The app has an auto unlock feature that I would not recommend using. I was able to walk almost 100' away from the unit and it was still connected. Leaving the auto unlock on will keep it from locking if you're in the immediate vicinity. You can order more than one of these and name them in the app. For example, you could have kids bikes, my bicycle, scooter, shed, etc. The app can handle as many locks as needed! Like I said earlier, there very few technology products that impress me anymore... this one did! Right down to the nice carrying case! The only thing that would have made this any better is if there was an app for my Galaxy Gear watch!

When I read of the RVing couple that had their bikes stolen right off the back of their RV in the dead of night while they were inside sleeping, I thought how vulnerable I was to the same kind o thievery. That's when I discovered NuLock. The feature that caught my interest was that if someone tried to steal the bikes from the couple that blogged about their loss, this might be the product that would have thwarted the theft. The NuLock looks like other heavy-duty cable locks, but with both ends of the cable inserted into a small black box. I verified the manufacturer's claims that if the cable were cut, moved, or even fiddled with, a short 110dB screech would sound, warning the wanabe-bicycle thief that he had better not mess with these bikes. If the vibration continued, such as the thief trying to figure out how to shut it off, it would then sound its classic screech for 30 seconds. There was no doubt it would arouse sleeping owners or others nearby and the thief would likely fade into the night empty-handed. And if he so brazenly decided to try to cut the 10mm braided steel cable with bolt cutters the screech would sound and not stop until the owner’s cell phone detected it within Bluetooth range. Now short of also extracting handcuffs and cuffing the thief, this looked like a pretty good deterrent to bike thieves. But one of the really clever features of the NuLock is the accompanying smartphone app, whereby you can both arm and disarm the lock - and the alarm - from the app. Additional features include the option to automatically disarm the lock and alarm when the smartphone is near the lock, and a small red LED light that advises you when the lock is activated and blue when not, as well as indicating when the batteries are low and need to be replaced. You can turn on or off the automatic feature on the app, as well as manually activate or deactivate the alarm. With the automatic feature turned on, you never need to fiddle with the lock. When you and your phone are nearby it deactivates, allowing you to open it and use whatever you had locked, and relock it again and set the alarm automatically when you and your smartphone walk away Nulock Keyless Bluetooth Bike/Motorcycle/Gate Lock IP44 Splash-proof Cycling Lock with 110db Alarm, 0.38" Diameter 31-inch Braided Steel Cable Nulock Keyless Bluetooth Bike/Motorcycle/Gate Lock IP44 Splash-proof Cycling Lock with 110db Alarm, 0.38" Diameter 31-inch Braided Steel Cable .

Gives me a peace of mind when I use this lock for my mountain and Road bike. I wouldn't use it for when the bike is in an area that is away from people as the cable somewhat is easy to cut, however the alarm when it's cut is loud and great deterrent when there are people around. Easy to set up. Be careful of the length you order. This length is great, however there are cheaper offers that are way shorter. Overall great product.

Fantastic! It works perfectly, its lite, flexible, easy to use and not expensive. I'm travelling quite a bit so this will be used not only on my bicycle but also my camera carrying case and suitcase! Superb item!

Crap doesn't work with my phone can't use it it's useless
