>>1723376>what am i even looking at herea Sturmklingel.
a lever on the handle pulls the cable which presses the bell against the tire.
more old school version
https://www.youtube.com/watch?v=IuOmjcBAApEtfw actually illegal in Germany . in the 70s they were banned as increasing traffic noise.
seams hilarious compared to noise cars and trucks make.
but i doubt you would ever get a fine from a cop for that, there going to be glad someone actually has a bell at all.
