I doubt any exercise on its own can make up for too many Big Macs and the inevitable fries with that.
Can't compare biking to swimming. I do know that I can ride a bike for 8 hours a day. I used to be able to run for an hour at the most till my knees gave out. I don't know how long the average swimmer swims, but it's probably not 8 hours, or even 1 hour. So for long, sustained effort, which uses up a lot of calories, I think biking may have an edge.
