I had bought a new electric scooter on a Monday. Bought an alarm and two locks: one for the trunk/battery case and another beefier one to luse on the wheel. I come out on the following Wednesday morning to find my bike is nowhere to be found. Called the police and we watched the CCTV of an older fellow stroll up to my bike at 5:20pm in broad daylight, unlock my wheel lock and push it away.

By some stroke of luck, on the way back home, I found my bike on the side of the road, just out of view of a security camera. I was able to drive it all of the 100m back home, although the steering lock is wonked out and the ignition has to be replaced.

I found a used kryptonic fogetaboutit lock on taobao and have been using that rediculous chunk of metal to lock it. Also have a cover on the way from the States.

Don't trust Chinese locks to lock even ur bicycle.
