Bicycle Alarm Aptel AG436A — vibration sensor, infrared remote, black

The Aptel AG436A bicycle alarm is a compact security device designed to detect vibrations and alert the owner with an audible siren. Housed in a black casing, the unit includes a vibration sensor and is controlled via an infrared (IR) remote that allows arming and disarming from a short distance. The system is intended to deter theft and provide short-term protection for a range of bicycle types without adding significant bulk or complexity.

Advantages

The vibration sensor provides immediate detection of knocks or tampering, triggering a loud alarm to draw attention. The included infrared remote enables convenient arming and disarming without physically handling the alarm module. Its compact size and neutral black finish allow installation on different bicycle frames and accessories with minimal visual impact. The device operates independently and does not require integration with other electronics on the bike.

Suitable for

• Everyday commuter bicycles parked for short periods
• City bikes and folding bikes stored in shared areas
• Bicycles left near entrances, garages or bike stands
• Situations where a portable, non-wired alarm is preferred

Key specifications

• Sensing type: vibration detection sensor
• Control interface: infrared (IR) remote control for arming/disarming
• Alert type: audible alarm/siren
• Color: black
• Form factor: compact, surface-mountable unit suitable for frame attachment

How to use

Install the alarm on a stable part of the bicycle frame or accessory using the mounting method provided or suitable fastening materials so the vibration sensor has firm contact with the structure. Insert any required batteries according to the product manual, then use the IR remote to arm the system before leaving the bicycle unattended. If the sensor detects vibration above its threshold while armed, the alarm will sound until it is disarmed with the remote or until the unit’s built-in timeout (if present) ends. Periodically check battery condition and mounting security to ensure reliable operation.

Usage recommendations

Place the unit where it has direct mechanical contact with the frame for reliable vibration detection, avoid mounting on loosely attached accessories, and keep the IR remote in a known, secure location. For longer-term security, combine the alarm with a robust physical lock and park in well-lit, visible areas.
