Leopard Lync smart alarm & theft monitoring device review - a neat alternative to AirTags and similar

Rather than relying on iPhones being close enough to connect via Bluetooth, the Leopard Lync instead employs GPS for 'global' coverage - but it comes at a premium

Cycling Weekly Verdict

The Leopard Lync is a sleek and streamlined security device that does exactly what it says on the tin. The alarm is loud enough to hopefully deter someone from running off with your bike without attracting a lot of unwanted attention, and the GPS tracking means you can keep an eye on where your bike is at all times. It’s not exactly hidden though, and with some brute force could be removed. It also is a subscription based service so the upfront cost isn’t the only one. But if you value the security of your bike, this is a useful addition.

Additional note: I started to get issues connecting the device to my phone and the app. Went through the standard restarting the phone, uninstalling the app, and trying to forget and reconnect the device. I tried to get in touch with customer support but several days later I haven’t heard anything back just yet. A few days later and it is still being buggy (images below while phone was in range and connected)

A relatively new company, Leopard Tech, aims to promote bicycle anti-theft, GPS tracking and IoT (Internet of things) connectivity. The idea is the sensors can use other tech connected to the internet to locate the device and ensure it won’t be lost or out of signal.
