I posted into a similar thread about a year ago and no one followed my logic and I doubt anyone will this time but here goes.
I love bike riding and the pure joy and good that comes out of it. It IMHO is imposable to put a price on it as most do saying it saves a gym membership or bike cost vs car cost. I would have a bike commute or not and almost all people still need at least one car.
When you love something there is a bias to justify it. I live 18 miles from work and I could commute and sometimes do. Its 36 miles both way and I know some that alternate riding and driving the other direction. The number no one looks at is (Time) I’m not a fast rider and my car commute thru the city is 30 minutes each way 5 hours a week. Biking will add at least 1 hour each way or 10 hours a week x 52 or 520 hours a year. If I value my time at even $10 an hour that comes out to a big number also of $5200. So given say the opportunity to work overtime I should drive to work waste some gas save some time make 10 times more money than I spent and then use a little of that money on the weekend take me and my bike out of town on the weekend in the car and ride a beautiful path all day not dodging pot holes and cars in the dark. Take the rest of the money / time I made and put it away for the N+1.
Everyone can justify however they want but for me the benefits are not something I can put a price on.
