Testimonials

Prevents theft and tampering.

Choku
Bike: De Rosa Protos, etc.

After having my Pinarello Dogma stolen, I started using AlterLock to prevent theft and tampering. Awareness is the key to prevention. I have installed AlterLock on all my bikes.

I was so relieved my bike was saved!

Luka Pyon
Bike: Merida Reacto 8000-E

I saw someone checking out my road bike, but I was too far away. He pulled a tool out of his pocket and broke the key. However, AlterLock detected the vibration and sounded its alarm, scaring him off.

It's great to have security and peace of mind.

Michelle
Bike: Specialized Venge Pro

I bought it after hearing the buzz about it. I used to have a standard wire lock and was worried about leaving it while shopping at the convenience store. With AlterLock's excellent security, I have peace of mind. It's rock-solid—no doubt about it!

FAQ

It can be attached to a standard sports bike using its bottle holder's base or in conjunction with your existing bottle holder.

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.

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.

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.

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 sensitivity of the alarm sound and vibration detection?

How to use this service

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.
