The 9 Best 31.8 mm Bike Bells (2023 reviews)

The crane 31.8 mm bike bell should be able to handle its purpose and duties with ease. The Crane is solid metal, feels premium and has a pure, loud, clear ring. It has a metal stopper that keeps the hammer from bouncing on the bell while you are riding. It has a very clear, resonant, appealing tone. The size is excellent, non-obtrusive, excellent quality.

Installation only requires a single hex key, takes about 3 minutes, and the strap that wraps around the bar is pretty forgiving of bar shape, which is nice. It is fairly easily to install with the flexible rubber insulated steel band. The copper finish is gorgeous, and the spring on the dinger (technical term) is strong enough that the bell will not ding unless summoned upon.
