In fairness I suspect the Dahon frame will be lighter and therefore capable of being a lighter/faster bike with the right components. The Carrera Intercity is more of a workhorse with much heavier rider capacity. You really never hear of Carrera frame issues and they often feature reinforcing in key areas you don't see on rival bikes but this would have a cost to weight. Their Subway model is renowned for strength and reliability in their hybrid range but uses the stronger 27.5" wheels rather than the more common/popular 700c. I think that is their design approach.
