I am starting the 2011 riding season with a balance of $277.72 in my bike fund. Let me explain what this means. I took the average cost per mile of operating my car and the average cost per mile to ride commute and run errands on my bike and subtraced it and came up with $0.34 a mile. That is money either saved or simply not spent. I keep track of the amount and multiply by the miles ridden when I commute or use my bike for errands. I do not count recreational riding. I subtract the money I spend on my bike from this fund. At the end of 2010 I had a positive balance of $277.72. I have already spent $61.95 of it on a new helmet and new gloves. The balance is currently $215.77. I pick my bike up from the shop after its tune up this coming Wednesday so the amount will be even less. But for 2011 I am starting in the black.
