Hello

I like the sound of ding-ding bells because it's not agressive and pedestrians know that a bicycle's coming, but I also sometimes need a horn like the AirZound.

So instead of using two different devices, I'd like to use a battery-powered bell/horn.

There are plenty of electric bells on eBay or Alibaba, so I was wondering if someone could recommend a brand + model that plays those two sounds.

Thank you.
