Velohorn | X5 Electric Bike-Horn

Velohorn | X5 Electric Bike-Horn

 The Velohorn X5 is a bike alarm and horn in one. Arm it with the remote before you walk away, and its vibration sensor sounds a loud siren the moment someone lifts, cuts or tampers with your bike. Out on the road, five sound modes turn it into a powerful horn. It recharges over USB-C, straps on without tools and shrugs off light rain.

  • I often leave my bike outside shops while running quick errands, and I wanted an extra layer of security beyond the lock. This alarm is easy to attach and simple to operate once you get familiar with the modes. I like that it's rechargeable, so there's no need to keep spare batteries around.

       Loud Enough to Make Thieves Think Twice 

      A lock slows a thief down, but it can’t make noise. The Velohorn X5 adds a loud siren that turns heads on the street and draws attention to your bike the moment someone tampers with it, giving you time to get back fast.

       Smart Sensitivity Real Threats Only 

      The built-in vibration sensor reacts to lifts, cuts and tampering. Adjust its sensitivity to suit where you park, so it guards your bike without going off at every passing truck or gust of wind.

       Arm It and Walk Away 

      Power it on with one touch, arm it with the remote as you leave, and disarm it when you’re back. When it needs a charge, plug in the USB-C cable. No batteries to swap.

      Excellent 4.8 / 5

      • Easy to Fit on My E-Bike

        I didn't want to drill holes or make permanent changes to my handlebars, so the silicone strap was a big plus. It took only a short time to fit, and the unit sits neatly in place. Having both riding alerts and a parking alarm makes it a practical little accessory.

      • Loud Enough to Get Attention

        I wanted something more noticeable than a regular bike bell, particularly when parking in busy public areas. The alarm is certainly loud, and the different modes are useful for choosing between a quick alert and a continuous sound. Charging through USB-C is convenient, too.

      • A Useful Addition to My Lock

        I already use a sturdy bike lock, but I like having another deterrent when I leave my bicycle unattended. Setting the alarm before walking away is straightforward, and the compact design doesn't make the handlebars feel overcrowded. It's a sensible extra precaution for everyday city riding.
