PADONOW Wireless Bike Alarm 115 dB USB-C Rechargeable — Remote-Controlled, Adjustable Sensitivity

PADONOW Wireless Remote Bike Alarm is a compact, USB-C rechargeable anti-theft siren with a 115 dB vibration sensor and remote control for bicycles, e-bikes, scooters and more.

This lightweight security device combines a high-decibel alarm, adjustable sensitivity and three-volume settings into a weather-resistant package that mounts without tools. It uses a built-in motion and vibration sensor to detect tampering, delivers a loud, attention-grabbing siren, and is recharged via USB-C for convenient maintenance. The unit also includes a remote fob for arming, disarming and triggering a panic horn from a distance, plus basic mounting hardware for quick installation.

How loud and adjustable is the PADONOW alarm?

The alarm produces up to 115 dB — loud enough to call attention and deter most opportunistic thefts. Volume is adjustable in three steps using the remote so you can match loudness to location and tolerance for false triggers. The siren uses a high-pitched tone designed to be noticeable in urban and outdoor settings.

• Maximum 115 dB output for strong audible deterrence
• Three volume levels selectable by remote control
• High-frequency siren tone for greater detectability

How sensitive is the motion detection and can I tailor it?

PADONOW provides three sensitivity levels so you can choose how easily the alarm trips: light touch, medium bump, or significant movement. That lets you prevent nuisance alerts from wind or passing vibrations while still reacting to genuine tampering. Sensitivity is set quickly with the remote, making on-the-fly adjustments simple when parking in different environments.

• Three sensitivity settings for light to heavy-trigger detection
• Remote-adjustable to adapt to different parking situations
• Reduces false positives while retaining theft-warning responsiveness

How is the alarm powered and how long does the battery last?

The alarm runs on a built-in 400 mAh Li‑ion polymer battery that recharges through a modern USB-C port. A full charge offers weeks to months of standby time depending on sensitivity and activity, and recharging is fast and straightforward from any USB power source. The rechargeable design removes the need for disposable batteries and simplifies long-term upkeep.

• 400 mAh Li‑ion polymer battery for reliable operation
• USB-C charging for universal, fast recharging
• Extended standby life; charge from power bank, wall adapter, or computer

Where can I mount this alarm and how weather-resistant is it?

Designed as a multipurpose alert device, the PADONOW alarm can be attached to bicycles, e-bikes, scooters, motorcycles, trailers, doors or windows using included zip ties and double-sided tape. The housing carries an IPX5 rating, so it withstands rain and splashes but should not be submerged. Lightweight construction and simple mounting hardware make it easy to move between vehicles or fixed locations.

• Includes zip ties and double-sided tape for quick mounting
• IPX5 water resistance protects against rain and splashes
• Portable and suitable for multiple vehicles and entry points

Who is this for? This PADONOW alarm suits riders and owners who want an affordable, portable, and simple-to-operate theft deterrent. It’s ideal for commuters, apartment-dwelling cyclists, scooter users, small-vehicle owners and anyone looking to add a loud, adjustable motion alarm without hardwiring. If you need a compact, rechargeable siren that’s easy to mount and control remotely, this device is built for everyday security and peace of mind.
