Review on 🚴 Sportout Copper Alloy Bike Bell: Classic, Loud Sound Ring for Road, Mountain, City, Sports, Cruiser & BMX Bikes by Mike Bucher

The bell is small but LOUD so don't be fooled. However, this call has a design flaw. Your handlebars must be the same diameter as the hole around the stem or it won't work. There is a screw holding it in place to keep the bell from slipping. In my third and fourth drawing I show what happens when the diameter gets larger: you end up with 2 contact points that completely muffle the sound and make the bell unusable. . One pin is the source of the spring on the trigger and the other is the trigger itself. You can see the two touching in my last shot.
