BikeSafe Watchman - Smart Motorbike Alarm

Smart alarm brain for your bike. No fobs. No fees. No faff.

Built for the weekday grind and Sunday blasts. Park for a flat-white or an overnight lay-up - Watchman keeps watch so you don’t have to.

What it does

• Phone = key: walk away → auto-armed; walk back → auto-disarmed.
• Knows the difference: warning flash for nudges, full horn/siren + lights if tampering continues.
• You set the line: simple slider for motion sensitivity and timers.
• Low draw: designed to sip power; deep-sleep for long lay-ups.
• Locked-down comms: encrypted pairing, secure boot, signed firmware.

Rider highlights

• No subscriptions: buy once, ride on.
• Use your own horn or a 12V siren; can pop brake light/indicators for visibility.
• Tip-over alert : after your set delay, it lets the world know.
• Indicator Whisper: optional audio nudge over your helmet’s Bluetooth headset.
• Battery watch: see your bike’s voltage health in the app.
• OTA updates: security updates and new tricks over the air.
