Good and discreet bike bell

- Bruno 10 March 2026

Got this bell in black version placed on a black handlebars with black handlebar tape. You can barely see them. Can hardly imagine this accessory having much impact on the aerodynamics of your road bike, as some claim. After all, we are talking about so-called recreational bikes, right? Just make sure you order the right size in terms of handlebar diameter.

Pros & Cons

Doesn't stand out at all. Black bell on black handlebars.
Easy to install
Sufficiently loud
No minus points for the time being

Nice and quiet bike bell for mountain bikes.

- Steffan 20 November 2025

This bike bell is silent when fitted properly. Even on a mountain bike! In addition, it is nicely concealed on your bike.

Pros & Cons

Nicely concealed
Silent

nice bike bell

- Carmen 15 August 2025

fine bike bell! The slim design leaves enough space to easily rotate my phone on my handlebars' phone holder. The cutouts through which the brake cables are routed are also handy. Especially on a road bike, where these run tightly along the handlebars. The design does make the sound of the bell not very loud, but so far I haven't had any problems with it.

Pros & Cons

Slim design
space for brake cables
not very loud
