This is the original BikeTac Bicycle siren. The least expensive bike siren on the market. This 120 db siren operates on a 9v battery and was originally designed to attach to the rear rack. Now available in rear rack mount or handlebar mount.

This siren has proven to be so effective and so much fun that we use it all the time. No longer do we have to patrol the busy downtown area with a whistle in our mouths.

This is a 6-tone 120 db alarm that mounts to the rear bike rack and has a momentary pushbutton switch that easily attaches within thumb reach on your handlebars.

The 9v battery box can be secured in your trunk bag or to your seat stay with the included hook and loop fastener (a.k.a. Velcro).
