Depends on what you call 'suitable roads'. I've cycled tank trails in Kansas right alongside speeding armored vehicles, fire trails in Montana, gone cross country many times on this bicycle.
From what I've seen in eight months here, the Cape offers a LOT of cycling opportunities, and the roads are some of the best I've encountered in forty one years of bicycling. So far as traffic goes, a real bicyclist, who follows the rules of the road and maintains a 360 degree watch, as I do, has nothing to fear anywhere, much less on the cape.
