Utter nonsense, seriously. The assumptions made in that article are beyond goofy. Comparing the cost of the bicycle itself to the cost of fare, of course, assumes that the public transit commuter doesn't own a bike at all. Imagine the psychological toll that might take on somebody. It also doesn't take into account the costs of potential physical health factors for either scenario, which admittedly have seriou pros and cons on either side. And the author's personal example, where it cost him an extra 11 pounds sterling to buy a single fare if he doesn't get the month-long pass, somehow he chalks that cost up to cycling? Totally daft. But, whatever.
I ride to work pretty often. For many years, I rode EVERY day to work. My needs and priorities change, and that's what determines my commute patterns. But, in my younger days when I didn't own a car and could take the train to Rutgers University, i knew that on days that i was flat broke, the answer was clear: I could bike in to class for $0.00, or I could take the train for $2.60. (Yes, some days, $2.60 was more than i could spare.... life as an undergrad....) Even on days that i took the train to class, i still had to ride my bike to the train station, anyway. I had to be multi-modal.
Nowadays, living and working in the suburbs, I'll either drive my truck to work, or bike to work. (My preference is to drive in on monday with a bike in the bed, and then ride home, leaving the truck at work for most of the week...) Public transportation exists between home and work, but only in the form of a bus. (Uck.) Between the walking to the stop, the waiting, the ride itself, and then the very long walk from the final stop to the workplace, it would take me well over an hour to use public transport to get from my home to my jobt. It would take me a little under an hour if i brought my bike along for the parts that i'd otherwise have to walk. It usually takes me 20 minutes to ride my bike to work-- 15minutes if i take a road bike. And, it costs me nothing. TBH, i don't even know what South Jersey bus fare costs, these days. But i know it ain't free....
So, for me, in the NJ suburbs, i can spend a few bucks and an extra couple of hours using the bus.... versus i can spend zero dollars and 40 minutes round trip riding my bike. (It takes me 10 to 15 minutes to drive in, depending on traffic and how lucky i get with red lights... and even with the cheaper gas and a 4 cyclinder truck, the gas expense does add up...)
