I use a bell. Other trail users love it 🙂 Especially walkers.

I always just shout "ring ring".
They laugh and move over…

two be fair those £1 snap on bells from tescos are ideal for smug 'ting ting' moments… worked well at SITS at the weekend when a couple of presumably 'riders wives' walking the pooch through the singletrack decided only after the last resort bell ringing that their number was up and had to hop out of the way….

Bells and whistles on…. whistle for a more formal get out of the **** way numpty…. and a bell for the ladies 😉

The whistle? It's louder and pisses the right people off… it discriminates by having an arrogant **** detector built in.

In Queensland it's law to have a bell on your bike at all times. Not that I have one though! 😀

Always used to have a bell, and found them dead useful for moving walkers politely. I seem to have phased them out right now though, just can't be arsed with more things on the bars.
