I save at least $150 per month on gas alone. Not to mention all the savings on wear and tear on my vehicle. Since bike commuting 15 years ago I have saved much and only purchased two bikes. One was stolen or I would still ride that one. I do own an old truck. I am not a vehicle hater. I just think if more of us commuted, North-American's health would be better, we would use less gas, polute less and be happier.
