Running through crowded paths and trails often means navigating around pedestrians, which can be a challenge for runners. The Runbell 3.0, a wearable warning bell designed to sit on a runner’s finger, provides an alternative to shouting out warnings, offering a more effective and considerate way to signal your approach.
The concept behind the Runbell was created by Kevin John Nadolny, a runner and entrepreneur. He first introduced the idea with the original Runbell, which resembled a two-fingered brass knuckle with a bicycle bell mounted on top. The design allowed runners to warn pedestrians without startling them or causing confusion, which can happen with verbal cues like “On your left!” Instead, the bell offers a more universal sound, reducing the risk of people stepping in the wrong direction upon hearing a shout.
The third version, the Runbell 3.0, builds upon this design with a few notable improvements. Unlike the original two-finger design, the new version is worn solely on the index finger, supported by the middle finger for added stability. It’s constructed from a single piece of cast stainless steel, giving it durability and a sleek appearance. The Runbell 3.0 also comes with four silicone adapters to ensure it fits comfortably on various finger sizes.
The bell itself is crafted by one of Japan’s leading bell manufacturers, though it’s not made by Crane, a well-known brand in the space. The bell features a nickel-silver alloy dome with a brass hammer. A single strike of the hammer with the thumb produces a resonant sound that can be heard from over 30 feet away (9 meters), making it an effective tool for signaling pedestrians in advance.

Currently available on Kickstarter, the Runbell 3.0 is offered in three color options: silver, gloss black, and matte black. Early backers can get their hands on one for a pledge of $29, while the planned retail price is set at $49.99.
With its sleek design and practical use, the Runbell 3.0 presents a useful tool for runners who want a non-verbal way to alert others on shared paths.
