Archive: Roadrat Gen1

Years of production: from 2006
Succeeded by the Roadrat Gen2.
The first generation Roadrat was where our flat bar road bike began: our mountain bike fit and handling, matched with fast road features, big tyre clearance and disc brakes.
Faster than a mountain bike on the road, more fun and versatile than a traditional road bike, the Roadrat was the perfect 'other' bike: swift and rugged, for commuting, road rides, gravel and adventures. Disc brakes have been in the Roadrat's DNA from the very start: the original 2006 version was one of the first road bikes to feature them.

Original Gen1 and Gen2 geometry records were not kept. These are the Roadrat Gen3 figures, which carried over the Roadrat’s compact road fit; earlier frames may differ slightly. Email size@cotic.co.uk if you need help with an older frame.
We didn’t keep a full archive record of the early Roadrats, so this page is shorter than most. If you own one and have photos or details to share, we’d love to hear from you at info@cotic.co.uk.
