Bikes win hands down by being the most efficient form of energy usage for transport. Walking requires a lot more calories to travel the same distance you can go on a bike. Those calories come from farming and that (diet dependent) very quickly can outpace any lifetime savings from using a bike. A bike is about ~99% efficient at converting energy into motion.
Bike is above walking?
Yup, this is perhaps surprising to some.

In terms of distance over energy? Damn right.
