Bike Alarm Tail Light with Remote

Well, after 6 years on the road, we finally had one of our bikes stolen. Ouch!

Because of this theft, we now combine this bike alarm/rear light with our bike chain locks.

If anyone moves the bike even a bit, it sounds off a loud warning beep. If it is moved again, an amazing loud siren goes off.

We control the alarm with a small remote that is attached to the handlebar when riding and is removable when we are off the bikes.

Only took about 1 minutes to install.
