For when the bike bell isn't loud enough. This Canadian-made product can be recharged with the nifty air pump supplied. (It can also pump-up push bike tyres.)

You pump up the air reservoir (which looks like a PET bottle but is much stronger) and you then have a VERY loud 120dB! horn warning/alerting device. Each recharge lasts about 50 short blasts.

* Volume control switch
* Handle bar mount (24 - 31mm)
* Weighs under 100g
