You want a set-and-forget alarm and do not mind changing batteries a few times a year.

You already charge lights and phones daily and want features like long range or tilt detection.
Choose smart if
Recovery matters most, or you park out of earshot and want phone alerts.

What to Check on Any 2026 Model
- Siren of 110 dB or more.
- Adjustable sensitivity.
- Water resistance for outdoor parking.
- A secure mounting method.
- Clear instructions for resetting and pairing.
Care Tips
Keep contacts clean, recharge before long rides, and replace mounting tape or straps when they show wear.

Alarm Maintenance Tips
- Test monthly: arm the alarm and gently shake the bike to confirm the warning chirp and siren.
- Check mounts: straps and tape loosen over time, especially after wet rides.
- Keep it dry: even water-resistant alarms last longer if wiped dry after rain.
- Replace remote batteries: a weak remote is the most common reason an alarm seems to stop working.
A few minutes of care keeps your alarm ready when you need it most.
