Customer Reviews
The installation of the app under Android from the app store was done quickly, and with a normal mount for the bottle cage, the installation under the bottle cage would also have been done quickly and easily.
For my special bottle cage mount, the included M5x16mm screws were a little too short.
About setting up the lock in the app:
Since the app unfortunately does not allow pre-taken pictures of the bike, and also the setup can only be completed with a picture, it is best to do the initial setup during the day and near the bike.
The recommended firmware update didn't work for me, but the lock still works perfectly.
The battery life is certainly not too short, in the course of the test of 2 weeks the battery level in the app dropped by one of three bars.
I can't judge whether or not the lock will send a thief running when the alarm is triggered, and how long it will take for the thief to remove the Alterlock. But for parking at the bakery or on a bike marathon it is a good investment in any case, light and inconspicuous, and sensational when the alarm goes off.
It was easy to fit and arming/disarming was faultless, the tracker facility is the main feature and being discreet under the bottle holder is a nice stealth touch.
I'd recommend AlterLock to any road cyclist. Having a cup of coffee while your expensive bike is parked outside is always quite a stress. Having a heavy lock is not an option. A lightweight lock is easy to crack. AlterLock add another layer of protection, in addition to my road bike lightweight lock. I feel more confident.
Also, having alarm on your daily bike while doing shopping or visiting gym gives a peace of mind.

Prevents theft and tampering.

Bike: De Rosa Protos and others
After my Pinarello Dogma was stolen, I started using AlterLock to prevent theft and tampering. Awareness is the key to prevention. I’ve installed AlterLock on all my bikes.
I was so relieved my bike was saved!

Bike: Merida Reacto 8000-E
I saw someone checking out my road bike, but I was too far away to do anything. He pulled a tool out of his pocket and broke the lock. However, AlterLock detected the vibration and sounded the alarm, scaring him off.
It's great to have security and peace of mind.

- Worried if even the most robust locks will be enough to protect it?

Communication Areas
AlterLock transmits data via Sigfox (the LPWA communication standard) when outside of Bluetooth range. LPWA makes it possible for the device to communicate on its own with low power consumption and low cost. Since Sigfox has different communication bands in different regions, Alterlock comes in several editions.
The European version is available in the following countries: Belgium, Croatia, Czech Republic, Denmark, France, Germany, Hungary, Ireland, Italy, Luxembourg, Portugal, Slovakia, Spain, Netherlands, United Kingdom and Finland.
FAQ
Can AlterLock be installed on any bike?
It can be attached to a standard sports bike using its bottle holder's base or in conjunction with your existing bottle holder.
What areas can I use this service in?
It can be used within Sigfox's service area (primarily Europe). Outside the service area, all functions will work within the Bluetooth transmission range. You can check the service area from this page.* Even within the service area, notifications may not reach your smartphone indoors where the signal is weak or in an environment with poor reception.
How is AlterLock different from Bluetooth trackers?
Bluetooth trackers are challenging to track once they leave your hands. AlterLock has stand-alone communication and GPS, so you can track your device wherever you go.
Can I check my location anytime?
This product is designed specifically for theft prevention. It cannot be used as a GPS tracker that continuously displays location information. Vibrations made in lock mode activate the GPS to significantly reduce power consumption and enable long-term tracking.
Can the device be removed easily?
If you try to remove the device, AlterLock detects the vibration and sounds an alarm to notify you, so you can rush to your bike. If you're still concerned, an additional anti-theft bolt and special tool are available. Please consider purchasing the device as a set. These items are not sold separately.
Is it possible to adjust the volume of the alarm and the sensitivity of movement detection?
Yes, it is. The movement detection sensitivity can be set to one of three levels.
