I've always wondered about the validity of these figures:

Because there is obviously a vast difference in how people both walk
and bicycle. I ride a lot, and at least 90% of the time at a fairly good
pace with elevated heart rate, breathing, etc. OTOH, when I walk I never
experience that sort of "pump", so I have a hard time seeing how I burn
less calories riding than walking. I get there faster on a bike, but
with more effort.
I also observe many people however who ride much more leisurely,
often coasting whenever possible, while I usually pump just as fast
downhill (unless it's very steep, which it isn't around here).
So I wonder which type of rider and walker they measured?
