CXWXC and Windmoon Wireless Remote Bicycle Horn and Motion Alarm with Four Sounds, Adjustable Volume, USB-C Charging and Handlebar Clamp Mount

Wireless horn and motion alarm in one bicycle accessory

Choose the CXWXC-logo or Windmoon-logo version of this wireless remote bicycle horn and alarm kit. The source lists a 120dB horn rating, four selectable sounds and adjustable volume. A separate handlebar remote lets the rider operate the sound and alarm controls while the main unit mounts to a compatible handlebar.

Four sounds and three volume levels

The product supports four sound choices, illustrated as horn, chirp, alarm and beep. Holding the remote + or - button cycles the sound, and the demonstration shows three volume levels. The 120dB figure is the supplier stated sound rating; actual sound level depends on the selected setting and conditions.

Arm, disarm and sensitivity adjustment

Press the closed-lock button to enter the pre-arm state. The source guide specifies a second confirmation after approximately 5seconds, when the alarm becomes armed. Press the open-lock button to disarm. During the pre-arm state, a brief press of + or - changes the sensitivity, with one, two or three confirmation beeps indicating the selected level. The demonstration shows responses to motion, vibration and tilt.

Touch power switch and remote pairing

Hold the main-unit switch for approximately 2seconds to turn power on or off. The guide identifies two beeps for power on and one for power off. After powering on, tap the main-unit switch to enter pairing mode; press any remote button while the unit is beeping. The guide states that the beeping stops once pairing is complete.

USB-C charging and weather-resistant housing

The source specifies a 300mAh rechargeable battery, USB-C charging and approximately 2.5hours per charge. It also lists approximately 30days of standby; actual operating time varies with use. An IP 66 rating is stated for the housing. Close the charging-port cover after charging and follow the supplied instructions for use and care.

Handlebar mounting and adjustable angle

The main clamp is shown for 22.2mm and 31.8mm handlebar diameters, with a supplied reducer and adjustable mounting joint. The remote uses its own bracket and rubber strap. Check the bar diameter, control clearance and secure fit before riding. The separate out-front adapter illustrated in one image is not included in this kit.

Approximate dimensions and listed weight

The dimension drawing shows approximately 100mm overall height for the horn and clamp assembly, with a 45mm-wide and 25mm-deep horn body. The remote is shown as 35x 35x 15mm. The product specification lists approximately 50g product weight; the figures are approximate source measurements.

Each option supplies the selected-logo horn, wireless remote, remote bracket, two rubber straps, two hexkeys, handlebar reducer, USB charging cable and multilingual instructions shown in the kit photo. The two brand choices have their own option images and prices. Bicycles and the separately illustrated out-front adapter are not supplied.
