Based in Dublin, Ireland, FiftyOne Bikes is a manufacturer of hand-built custom road bikes and factory-built gravel bikes. Every bike is made to our exacting standards and designed to the especially textured understanding we have of the needs of each individual rider.
FiftyOne Bikes was founded in 2016 by former international rider Aidan Duff, in response to the disappearance from top-end race bikes of the custom options that he had always enjoyed during his career.
