VIVI Bike Alarm Lock Anti-theft Disc Brake Lock

VIVI Bike Alarm Lock — Anti-theft Disc Brake Lock

A sudden wind, a crowded café terrace and the uneasy pause before you leave your e-bike unattended—the VIVI Bike Alarm Lock turns that short moment into reliable protection and peace of mind. Compact and purposeful, it clamps into the disc brake rotor and adds a loud, attention-getting alarm to deter thieves and vandals.

Lightweight yet rugged, the lock suits urban commuters and tour riders who pause frequently. Its motion-sensitive alarm alerts nearby passersby while the sturdy locking pin resists tampering. Weather-resistant construction and a compact profile make it easy to carry or mount on a frame bracket, so protection is always close at hand.

Practical benefits include fast one-handed installation, audible theft deterrence, and compatibility with most disc-brake setups found on electric bicycles. Ideal for quick stops, overnight parking in low-risk areas, and as a visible secondary deterrent.
