Before You Start

Tools you will need

Adjustable Wrench (included in your bike tool kit)
Multitool with Allen Wrenches (included in your bike tool kit)
Cable snips

Preparation

Power off the bike.
Work in a bright area where you can easily access your handlebars.
Charge the horn fully before installation. The indicator light will change color when fully charged.

Steps | Installation

Step 1: Install the Mounting Clamps

Insert the rubber spacers inside both clamps.
Wrap the two clamps around the headtube, directly below the handlebars. Insert the first screw from the clamp without the bracket into the clamp with the bracket.
Insert the second screw and tighten both screws alternately to apply even pressure.
Ensure the horn mounting bracket is pointing forward before fully tightening.

Step 2: Attach the Horn

Remove the mounting bracket screw, slide the horn onto the bracket, then reinsert the screw and nut and tighten with your multitool and wrench until fully secure.

Step 3: Install the Wired Switch

Wrap the silicone strap around the inside of the left grip to secure the switch. Do not pull too hard or the silicone may tear.
Use the included zip tie to secure the horn cable to the mounting bracket so it doesn’t hang low, then trim the excess zip tie
Route the remaining cable along the existing handlebar cables and wrap it neatly to keep everything organized.

Note: You can place the switch wherever it feels most comfortable. We recommend the left side since it sits opposite the throttle.

Using the MOD Alert Horn

Activate the Horn

Press the wired switch once. The horn will sound until the button is released.
A full charge allows approximately 2,000 activations.

Using the Car Alarm Feature

The horn includes a vibration-triggered alarm.

To arm:

Press the lock symbol button on the remote.
The wired switch will flash red to confirm activation.
When armed, any vibration will trigger the alarm.

To disarm:

Press the unlock button on the remote.
The wired switch will flash red to confirm the alarm is off.

Activating the Horn Remotely

Press the bell button on the remote to sound the horn wirelessly.
Useful for locating your bike in a crowded area.

Adjusting Sensitivity

Press the lightning bolt button on the remote.

High Sensitivity – wired switch flashes 3 times
Medium Sensitivity – flashes 2 times
Low Sensitivity – flashes 1 time

Sleep Mode

The horn enters sleep mode after 40 minutes without vibration (alarm off).

Any vibration wakes the horn from sleep.

The horn will not enter sleep mode while the alarm is armed.

Troubleshooting

Horn does not activate → The battery may be empty. Fully charge the horn using a USB-C cable until the indicator light changes color.
Horn activates too easily → Sensitivity may be set too high. Use the lightning bolt button to lower the sensitivity level.
Alarm does not arm → The horn may be in sleep mode. Tap the bike to wake the unit, then press the lock button again.
Remote will not trigger horn → The remote battery may be low or the signal may be blocked. Replace the remote battery and point it toward the horn.
Wired switch not responding → The switch may not be secured tightly. Re-wrap the silicone strap and confirm the switch is firmly in place.
Alarm does not trigger when the bike is touched → Sensitivity may be too low or the alarm is not armed. Increase sensitivity or press the lock button to arm it.
Horn triggers on its own → External vibration or shock can cause false alarms. Lower sensitivity or reposition the horn on a more stable mounting area.
