Description

120dB Anti Theft Bike Alarm, Bicycle Alarm with Motion Sensing, Bike Security Alarm

Know the moment someone touches your bike: motion-sensing security mode triggers a 120dB alarm
Stay seen and heard while you ride: switch to riding mode for four alert tones
Charged and ready in minutes: a full charge takes just 20 minutes over USB
Rides through the rain with you: IPX4 waterproofing protects the battery and electronics
On your bike, no tools: tool-free mounting attaches to a bike or e-scooter handlebar

Coming back to find your bike gone, or wondering if someone's testing the lock, is the kind of moment this alarm is built to prevent. Motion-sensing security mode fires a 120dB alarm the instant your bike is disturbed, and switching to riding mode gives you four distinct tones to stay safely visible in traffic. The whole thing is IPX4 waterproof, so rain and splashes never put it out of action.

Three buttons handle everything: hold the left one to arm the motion-sensing mode, the right one to disarm it, and the middle one for riding alerts, with a double-click cycling through the four tones. A 200mAh lithium battery reaches a full charge in just 20 minutes over USB, and the tool-free mount attaches the compact ABS housing to a bike or e-scooter handlebar without tools.
