Comfort bikes are still fitness bikes! There's more to cycling than calories and cadence, you want to enjoy yourself, not hammer your hips and knees, break your back, crank your neck and get to know the floor.. sit up and see the world! Light bikes with fat tyres, raised bars and comfy seats are gonna make riding enjoyable. And that's healthy.
I like the Electra Townie Flatfoot. You sit upright, and can pedal straight-legged for efficiency - yet you can still stand on the ground whilst seated! And having the crank forwards also works your arms as well as your legs. There's nothing not to like.
