Rechargeable 115dB Anti-Theft Vibration Alarm PRO w/ Wireless Remote

High-Decibel Acoustic Defence for Modern E-Bikes

Opportunist bike thieves rely on silence and darkness. The 115dB Vibration Alarm PRO eliminates both the second anyone touches your bike. Powered by an advanced 3D triaxial accelerometer and a piercing high-decibel siren, it triggers an instant warning chime on light tampering, followed by continuous ear-splitting acoustic blasts if movement continues.

USB-C Rechargeable: Unlike cheap alarms that require replacing AAA batteries every few weeks, the PRO edition features a high-density lithium-ion battery engineered to hold a charge for up to 3 months in freezing European winters.

Why It Stops Thieves Instantly:

• Piercing 115dB Multi-Tone Siren: Loud enough to be heard through walls and double-glazed windows. Disorients thieves immediately and forces bystanders to turn their heads.
• Smart 2-Stage Tamper Detection: Light bump? Emits a brief 2-second acoustic warning chirp to prevent accidental false alarms. Sustained movement or tilting? Triggers the full 115dB continuous alarm cycle.
• 7-Level Sensitivity Calibration: Fine-tune vibration sensitivity from a gentle touch to a forceful push directly from your remote—preventing false alarms caused by heavy traffic or gusty wind.
• Encrypted Wireless Remote (Up to 50m Range): Arm or disarm with a click from your pocket. Features a built-in "Vehicle Finder" beacon mode that chirps so you can locate your bike in crowded train station racks.
• SOS Crash Sensor: Automatically detects severe frame tilt (>45° angle) during a crash and sounds an emergency rescue ping if you are incapacitated.
• Dual Secure Mounting: Install it under your saddle or clamped firmly to your frame tube using the reinforced bracket or heavy-duty zip ties.
