YOHOOLYO Motorcycle Disc Lock — 7mm Pin, 110 dB Alarm, Waterproof with Reminder Cable

YOHOOLYO Alarm Disc Lock is a waterproof, crash-resistant disc brake lock with a 110 dB vibration alarm, 7mm hardened pin, and a 5ft reminder cable to help prevent motorcycle, scooter, and bicycle theft.

When parking outdoors or in shared spaces, visible physical security combined with an audible alarm deters opportunistic thieves. This YOHOOLYO disc brake lock pairs a forged stainless-steel body and a 7mm locking pin with a built-in 110 dB vibration sensor, plus a 5-foot reminder cable so you don’t try to ride away with the lock still attached. It arrives with two keys, backup batteries, an Allen wrench, and a padded carry pouch for convenient transport and maintenance.
