Archive: Roadrat Gen2
Years of production: until 2014
Preceded by the Roadrat Gen1. Succeeded by the Roadrat Gen3.
The second generation Roadrat refined the original flat bar road bike, before the Gen3 added the Escapade down tube and a bolt-thru fork in 2014.
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.
