Intelligent Alarm Brake Lock

Lock and alarm combo is a great deterrent

I found it easy to use, I don't know how long the batteries last but on most power repaired stuff. The batteries usually last quite a while.

Quick to
Apply. Quick to release . I do not use a chain or leash with it. I just put it on brake roder. And I’m not away from trike long. So it fits for me in my area.

The alarm works great but the biike tips to much on slgt humps on the rpad.in my city there is tree roots pushing up tje sidwallke every ten feetmuc.h to tipee to ride. I didn't intend on returning the bicycle but because I throw it through the box away now I'm stuck with it otherwise I would return it for a refund and buy something else it's safer for me I'm 70 years old so it's just a little too sketchy

Have not been able to use my E bike yet , or the alarm brake lock
