On-One Pompino


On-One Pompino

On-One Pompino Fixie Bike

Tried and trusted the On-One Pompino has always been close to our hearts. The original hack bike, perfect as an urban commuter, pub bike and more. The Pompino is versatile enough to handle whatever the ride throws at it without any unnecessary complications- only a track bike has less moving parts.

Running a single speed set-up is all about ease of use and ultra-low maintenance. Our steel Pompino remains so popular because it combines this simplicity of bike ownership with responsive geometry for a fun and zippy ride. Plus, as usual, the frame and components are all superb quality so you get years of good service from your trusted steed.
