Absolutely, public transport, where well-developed, generally beats all other modes, including walking (although that is obviously hard to measure, and one doesn't count the miles walked inside houses, etc.).
It is quite touching that someone might think cycling could possibly be the 'most common form of transportation' anywhere, vague though that is. In the old phrase (not mine), it should be the 'default non-walking mode of transport', but I'd bet it isn't that anywhere in the world.
It's one of those things where it's important to know what is being measured. I'd be surprised if there was any country where bike riding is the most common form of transport if you count aggregate passenger miles.
