wsdcam Bike Alarm USB-C Rechargeable 110dB with Remote — Adjustable Volume & Sensitivity

WSDCAM's USB-C rechargeable bike alarm is a compact, vibration-triggered 110dB security device with remote control, adjustable volume and sensitivity, and multiple mounting options for bikes, e-bikes, scooters, motorcycles and trailers.

If you want a small, weather-resistant anti-theft alarm that alerts you to bumps, pushes or attempted tampering, this unit combines a loud siren, remote arming/disarming, and flexible installation methods. It uses a built-in 700mAh battery with USB‑C charging, supports up to eight remotes, and offers three volume levels plus seven sensitivity settings so you can tune it for crowded urban areas or quiet storage spaces.

How loud is this alarm and can I adjust the volume?

The alarm produces up to 110dB—loud enough to startle intruders and draw attention. You won’t be stuck with one setting: choose from three volume levels to match your surroundings.

• Maximum output: 110dB for high-visibility deterrence.
• Three selectable volume levels to avoid unnecessary disturbance.
• Remote-controlled arming/disarming to prevent false triggers.

How sensitive is the motion detection and can I fine-tune it?

Sensitivity is adjustable across seven steps so the alarm reacts to anything from a light touch to strong impacts. That flexibility helps prevent false alarms from wind or passersby while making sure serious tampering still triggers the siren.

• Seven sensitivity levels from very gentle to high-impact detection.
• Useful for different mounts: frame, luggage, trailer or stand-alone use.
• Pair up to eight remotes and multiple alarms for fleet or multi-vehicle setups.

What mounting and weather protection does it offer?

The kit includes three mounting choices—bracket, zip ties and double-sided tape—to fit smooth or irregular surfaces. The main unit carries an IP65 rating so it stands up to rain and splashes during regular outdoor use.

• Bracket for secure, repositionable mounting on frames and racks.
• Zip ties for irregular or temporary attachment points.
• Double-sided tape for fast, low-profile installation.

How long does the battery last and how is it charged?

A built-in 4.2V 700mAh lithium cell charges via the included USB-C cable in about three hours. Depending on activation frequency and settings, a full charge typically provides weeks to months of standby use.

• USB-C fast charging using a DC5V adapter (included cable only).
• About 3 hours to fully charge; runtime varies with use frequency.
• Low-battery and charge-level indicators to avoid surprises.

Who this is for: riders, commuters and vehicle owners who want an affordable, flexible deterrent that’s easy to mount and simple to operate. It’s suited for bicycles, e-bikes, motorcycles, scooters, trailers, and even gates or luggage—anywhere you need a compact, loud alarm with remote control and adjustable sensitivity. If you need a weather-resistant, rechargeable alarm that you can tune for busy city streets or quieter storage areas, this WSDCAM unit delivers practical features without complicated installation.
