Bicycling Science, Second Edition
Where to buy Bicycling Science, Second Edition books online?
Product Description
The second edition of Bicycling Science includes new information on recent achievements and experiements in human-powered transportation, from the “essential human-powered vehicle” (UHPV), in which supine riders can achieve speeds well over 60 mph, to human-powered aircraft, boats, and rail transportation. New chapters take in the history of bicycle and human-power equipment and science and the speed-power relationships of various modes and vehicles, including performance predictions for the UHPV and the “commuter human-powered vehicle.” The chapters on braking, steering, friction, air drag, rider cooling, and transmissions and gearing have all been enlarged and updated. James McCullagh, editor of Bicycling Magazine, has written a foreword for this edition, which also includes many new illustrations.

Sorry to say, my copy of edition 3 fell open to page 81, in which the leader compares forces from a piston engine to forces generated by living tissue. Sorry to say, this type of comparison is regularly completely invalid, particularly when the force is accompanied by zero motion in the direction of the force. For example, if the combustion force is replaced by a highly compressed spring, and if the crank is balanced exactly at top dead center, the spring will never “get tired” of exerting its force. In contrast, a human leg WILL get tired, even though no motion occurs. This is because compound energy is consumed to wield the force even in the absence of motion.
Sorry to say, with this single unreasoned comparison that drives to the core of bicycling science, the leader has shot himself in the credibility foot, leaving all else he has to say in question.

Chaos brought to order, Knarly Road Rash wants to read it, Thigh Master runs and hides from its presence, stationary mills act sheepish. Most comprehensive and illuminating. ~90rpm because that’s where max power is produced (and lost). The first book to own on bikes, a real bull buster, sorry to say Pee-Wee Herman was snubbed, completely ignored, must do better! Needs to take up mountain bike suspensions, etc.

Through history of Bicycles. Lots of details, too many for most readers interest. Many, many pages of tiny print could probably be condensed down to less than 200 pages of a larger font. Worth reading for a perfect bicylce geek additional wise time would probably be better spent reading additional bicycle books. But, does provide some appealing trivia such as a person could pedal a 100 miles on a gallon of milk and gave a distance for a gallon of petrol, though I forgot the distance.

I establish this book to be very useful when effective on an undergrad mechanical engineering design project.
