I bought an electra bell at the LBS that makes the classic "ring" sound I remember from the old days. pretty cool. sometimes I ring it just to hear the sound. Downside; just like Hobart, above, the bell makes noise every time I hit a bump or rough road. I'm jingling a lot of the time!

I've learned not to use it with peds because they freak out and don't know which way to go. so I just slow way down and pass them as far away as I can get on the left without making any noise.
