There are few things dorkier than putting a bell on your bicycle.
Once you do that, it can only lead downhill into a world of helmet mirrors, handlebar tassels, and high visibility ankle bands. But you should put a bell on your bicycle. It makes life easier for you and everyone around you.
It is universally uncool for any cyclist outside an eight-year old on a Huffy to have a bell on their bicycle. It is somehow better for a cyclist to yell “on your left,” “behind you,” or nothing at all as they zoom past pedestrians, hikers, dog walkers, baby strollers, or horrible drivers.
