Most Fuel-Efficient Vehicle that I own.
Thanks Mike for working your wonders on my old machine. Now, just like my car, I have a hybrid bike. Half racing bike (with tires that are thinner, gears for higher speed, etc.) and half mountain bike (Thicker frame, good handlebars and shifter components). In the end, I have a bike that is fast through the city, yet can take the abuse of jumping over curbs and any other obstacles (like old ladies) that might get in my way.
