Today I noticed again that other cyclists react incorrectly to the “moped horn” that I now use a lot.

They are shocked because they think that I am cycling dangerously fast and when I use the simple bicycle bell (which is in my velomobile), they do not hear it properly.

So I will try to reinstall the dual tone bell that I used to use on Quest 215 . That sounded friendly and I was able to operate it from the inside.

This 11 year old video shows how it worked.
