YOHOOLYO Alarm Disc Lock for Motorcycle Scooter Bike — Red, 110 dB Alarm, 7mm Hardened Pin, Waterproof with 5ft Reminder Cable

YOHOOLYO Alarm Disc Lock is a compact, weather-resistant disc-brake lock that combines a 110 dB vibration-triggered alarm with a 7 mm hardened pin and a 5 ft reminder cable to deter theft and protect parked motorcycles, scooters, and bicycles.

Designed for riders who leave their two- or three-wheeled vehicles unattended in public or residential areas, this lock pairs solid mechanical resistance with an audible alarm and visual reminder cable. Its corrosion-resistant forged stainless-steel body, straightforward one-press activation, and included carry pouch make it practical for daily use. The package also includes two keyed locks, spare batteries, and an Allen wrench for maintenance, so you can secure your vehicle quickly and maintain the device over time.

How does the alarm system help protect my motorcycle or scooter?

The built-in alarm reacts to impact and vibration, emitting up to 110 dB to startle thieves and draw attention. The loud sound increases the likelihood of intervention by passersby and discourages opportunistic tampering. Battery redundancy and waterproofing help keep the alarm functional in varied conditions.

• 110 dB vibration-triggered alarm for immediate deterrence
• Waterproof housing maintains function in rain and wet environments
• Multiple internal batteries plus spares included for reliable operation

Is the lock strong enough to resist forced removal?

The lock’s 7 mm pin and forged stainless-steel construction provide a solid mechanical barrier against common tampering methods. One-press engagement makes it quick to set while a visible, compact design covers the disc hole to impede wheel movement. It’s built to resist cutting and pry attempts that target weaker locks.

• 7 mm hardened locking pin for robust resistance
• Forged stainless-steel body reduces corrosion and increases strength
• Compact profile fits most disc brake holes up to 6 mm thickness

What vehicles and disc sizes are compatible with this lock?

This lock fits motorcycles, scooters, bicycles, e-bikes and other vehicles that use disc brakes with holes or spokes accessible for locking. It’s designed for disc plates with up to approximately 6 mm thickness; always confirm clearance and hole diameter before purchase. The included 5 ft reminder cable offers additional visibility between the handlebar and lock to prevent accidental rides with the lock engaged.

• Compatible with motorcycles, motorbikes, e-bikes, scooters and bicycles
• Designed for disc brakes with up to ~6 mm thickness
• 5 ft reminder cable reduces risk of riding off with lock still attached

What’s included and how do I maintain the lock?

The package is prepared for immediate use and routine upkeep: two keys per lock, spare batteries, an Allen wrench for disassembly, and a carry pouch for storage. Periodically check battery level, clean any grit from the locking mechanism, and keep the unit dry when not in use to prolong service life. Replacement batteries are standard cells and easy to swap.

• Two security keys, spare batteries, Allen wrench, and carry pouch included
