BikeSafe Watchman - smart alarm brain for your bike
Real security you’ll actually use: your phone becomes the key, the bike stays protected, and there are no fobs and no monthly fees.
What it does
-
No remembering: in Auto Mode, proximity detection can automatically arm when you walk away and disarm when you return.
-
Smarter alerts: escalation from warning to full alarm using your horn/siren plus indicator/brake light outputs.
-
Set it once: adjust sensitivity and timing in the app — no laptop, no special tools.
-
Battery + ride stats: check battery voltage, percentage, lifetime min/max voltage history, and riding time.
-
Turn-signal reminder: “Indicator Whisper” plays an optional audio clicks to your phone/helmet headset after a configurable delay.
-
Over-the-air updates: firmware updates via the app with cryptographic signature verification.
Built for real-world riding
-
No subscriptions: buy once, ride on.
-
Multi-phone pairing: supports up to 2 bonded phones with whitelist security.

Low-effort security: designed to run day-on-day without draining your bike or your phone.
