YOHOOLYO Motorcycle Disc Lock Alarm — Black, 7mm Pin, 110 dB Waterproof with 5ft Reminder Cable

YOHOOLYO Alarm Disc Lock is a weatherproof, all-metal disc brake lock with a 110 dB motion alarm, 7 mm locking pin, and 5 ft reminder cable to deter theft of motorcycles, scooters, and bicycles.

This compact anti-theft device combines a loud built-in alarm with a rugged metal body and waterproof construction so you can lock your bike and ride away with greater confidence. It fits most motorcycles, scooters, dirt bikes, and bicycles that have brake disc holes or spokes. The kit includes spare batteries, two keys, an Allen wrench, and a carrying pouch for secure storage and easy transport.

How loud and responsive is the alarm?

The built-in alarm reaches up to 110 decibels—loud enough to draw attention and deter potential thieves. A motion sensor activates the alarm after a short five-second delay to reduce false triggers, and the unit is designed to be sensitive to attempts at tampering or movement.

• 110 dB alarm level for high audibility
• Motion sensor with 5-second activation delay
• Sensor reacts to vibrations and impact for real-time alerts

Will this lock fit my motorcycle or scooter?

The YOHOOLYO disc lock uses a 7 mm hardened steel pin and rotates 360 degrees to lock into most brake disc holes or spokes. Its compact design and adjustable positioning let you secure wheels on a wide variety of two- and three-wheeled vehicles.

• 7 mm locking pin compatible with most discs and spokes
• 360-degree positioning for flexible installation angles
• Suitable for motorcycles, scooters, bicycles, and dirt bikes

Is the lock durable and weather-resistant?

The housing is all-metal and engineered to resist impacts and harsh weather. The alarm module and lock components are corrosion-resistant and waterproof so the unit continues to function after exposure to rain or grime.

• All-metal construction for abrasion and impact resistance
• Rust-resistant finish and waterproof alarm housing
• Designed for repeated outdoor use without performance loss

What accessories are included and how long does the battery last?

The package comes with six internal batteries installed plus six backup batteries for extended service life, two security keys, an Allen wrench for maintenance, a 5 ft reminder cable, and a carry pouch. Extra batteries and keys mean less downtime and easier long-term ownership.

• 6 installed batteries + 6 spare batteries for extended use
• Two keys per lock and an Allen wrench for disassembly
• 5 ft reminder cable to prevent riding with the lock engaged
• Carry pouch for storage and transport

Who is this for? Riders who want a compact, high-decibel deterrent for everyday protection—commuters, scooter riders, urban motorcyclists, and cyclists—will appreciate the YOHOOLYO disc lock’s blend of loud alarm, durable construction, and practical accessories. It’s designed for anyone who needs a portable, weatherproof anti-theft device that fits most wheel types and comes ready with spare batteries and keys.
