Buying Guide
Key factors to consider
- Alarm loudness (dB): Higher dB alarms deter thieves more effectively but can be louder than needed in quiet environments. Most options here range from 110dB to 113dB.
- Remote range: A longer range offers more convenience when you’re away from your parked bike. Ranges vary from about 66 ft to 800 ft depending on the model and environment.
- Waterproofing and weather resistance: Look for IP ratings (IP55, IP65, IP66) to ensure performance in rain or dusty conditions.
- Sensitivity settings: Multiple levels (7 levels are common) allow you to tailor the trigger from gentle movement to strong impacts.
- Volume controls: Several products offer multi-level volume settings to suit different locations and noise levels.
- Remote features: Some alarms include locator or vehicle search functions, SOS emergency modes, and multiple remotes; consider whether you want one or two remotes and how you’ll use SOS alerts.
- Installation and compatibility: Ensure the unit fits your handlebars, mounts discreetly, and suits your bike type (bike, e-bike, motorcycle, scooter).
- Power and reliability: Check battery life, whether the remote uses replaceable batteries, and how easy it is to rearm after activation.
