NEIKO Motorcycle Disc Brake Lock with 110 dB Alarm — 52908A Black, Universal Fit & Weather-Resistant

The NEIKO 52908A is a heavy-duty metal disc brake lock with a built-in 110 dB alarm and motion sensor designed to deter theft on motorcycles, scooters, and bicycles.

If you park a two‑wheeler in public or store it where unauthorized movement is a concern, this compact disc lock adds an audible and physical barrier to theft. Constructed from corrosion-resistant metal, the lock fits most brake rotors with a simple 360° placement, triggers a loud siren when jolted, and includes a visible reminder cable so you don’t ride off with the lock engaged.

How loud and responsive is the alarm?

The lock’s built-in alarm reaches up to 110 dB, loud enough to draw attention in busy areas. A five‑second motion sensor delay prevents false triggers from minor vibrations while still responding quickly to intentional tampering.

• 110 dB alarm output for strong audible deterrence
• 5‑second delay activates the motion detection
• Shock/movement sensor detects tampering and vibration
• Battery-powered system with included batteries

Will it fit my motorcycle or bicycle brake disc?

The 52908A is designed as a universal disc lock to accommodate most rotors and wheel designs with spoke or perforated discs. Its compact shape and 360° placement make it adaptable to many brake hole layouts; always verify clearance and hole diameter before use.

• Universal fit for many motorcycles, scooters, mopeds, and bicycles
• 360° placement allows flexible positioning on the rotor
• Works with rotors that have holes or open spoke areas

How durable is the lock in weather and daily use?

Built fully from metal, the lock resists rust and moisture to handle outdoor storage and frequent handling. The weather‑resistant construction helps preserve both the locking mechanism and the alarm electronics over time.

• All‑metal body for enhanced corrosion resistance
• Weatherproof design protects internal components
• Includes storage bag to keep parts clean when not in use
• Simple mechanical key system with two keys included

Who is this for? Riders who want an affordable, portable layer of protection for parked motorcycles, scooters, mopeds, and bicycles will find the NEIKO 52908A useful. It’s best for daily commuters, urban riders, and anyone looking to add both a visible deterrent and a loud alarm to discourage opportunistic theft.
