RUBY.Q 2-Pack Alarm Disc Locks for Motorcycle Scooter E-Bike — 7mm Pin, 110 dB Alarm, Reminder Cable

RUBY.Q 2-pack alarm disc locks are compact disc-brake security locks with a 110 dB vibration alarm, 7 mm locking pin, reminder cable and carry pouch to help deter theft of motorcycles, scooters and bicycles.

This set includes two color-coded disc locks (red and black), each fitted with an electronic alarm that senses vibration and emits a loud 110 dB alert. Supplied accessories—Allen wrench, spare keys, a 5-foot reminder cable, storage pouch and button-cell batteries—make these locks ready to use right out of the box. The heavy-duty steel body and weather-resistant finish are built for everyday outdoor parking and short-term security when you step away from your vehicle.

How loud is the alarm and what causes it to trigger?

The alarm produces up to 110 dB, loud enough to attract attention nearby and discourage casual thieves. It activates automatically when the lock senses impact, movement or tampering while engaged on a brake disc, providing an audible deterrent in public or semi-public settings.

• 110 dB high-decibel siren for immediate attention
• Motion/vibration sensor triggers alarm on impact or jostling
• Automatic arming after single-button lock operation
• Battery-powered module for continuous monitoring

Will these disc locks fit my motorcycle, scooter or e-bike?

They fit vehicles that accept a disc lock with a pin up to 7 mm thick—common on many motorcycles, scooters and some e-bikes. Always check your disc brake hole diameter and clearance for caliper parts before purchase to confirm compatibility.

• 7 mm hardened locking pin to secure through disc rotor holes
• Compact profile designed for motorcycles, scooters, electric bikes
• Use on left or right discs depending on rotor access and clearance
• Included reminder cable helps prevent riding off while locked

How durable and weather-resistant are these locks?

The casing is forged from heavy-duty steel with coatings to resist rust and daily exposure to the elements. The locking pin and body are engineered for strong mechanical resistance, and the alarm module is designed to function in wet conditions, although long-term submersion should be avoided.

• Heavy-duty steel construction for impact resistance
• Water-resistant coating to stand up to rain and road spray
• Corrosion-resistant components for longer outdoor use
• Replaceable LR44/AG13 button batteries for simple maintenance

How simple is setup, operation and battery replacement?

Setup is straightforward: insert the supplied button cells, lock the device with a single press and the unit enters alarm-ready mode. Two supplied keys unlock the mechanism; the compact Allen wrench and the carry pouch keep accessories organized for quick field use.

• One-press locking with audible beep to confirm arming
• Each lock uses six LR44/AG13 button batteries (included plus backups)
• Two security keys included per lock for mechanical release
• 5-foot reminder cable reduces risk of attempting to ride off while locked

Who is this for: Riders and commuters who need a portable, high-decibel physical deterrent for short-term parking—ideal for motorcycle and scooter owners, urban e-bike users, and anyone who wants a compact backup anti-theft device. This kit is aimed at people seeking straightforward installation, loud audible protection and a weather-resistant build for everyday use.
