Review on 🚲 SuperInk 2 Set Wireless Bike Alarm: Anti-Theft, Vibration Sensor, Waterproof, Super Loud 113dB Alarm by Johnny Black

I installed this system on my recumbent trike. It fits perfectly under the seat and is mostly hidden. I can turn the alarm on or off from a few meters away. To be honest I haven't turned it on yet to test it, but I tapped the bike and the warning chime went off. I have close neighbors so I'll test it in a more open area. The instructions aren't great, but I mostly used it since it came set up from the factory and wasn't set to max sensitivity, so that worked for me. I can get another block for my golf cart. By the way, I have one block on my recumbent trike and one on my wife's bike. Fortunately, they were tuned to different frequencies. One problem, there are no instructions on how to change the battery in the remote control, although it appears that the case is opened with a small coin. So far I would recommend these units.
