Electric Bicycles: A Guide to Design and Use / by William C. Morchin and Henry Oman. For much of the world, bicycles are a transportation mainstay. Electric bicycles--powered by a rechargeable battery pack--are proven to deliver the highest possible energy efficiency, even compared to pedal bikes. A transportation alternative to fossil fuels, electric bicycles are fast catching on, in part because they don't require factory assembly. End-users can easily construct them with available components. The text reveals important techniques, data, and examples that allow readers to judge various propulsion setups--used in both home- and factory-made bikes--and estimate speed and travel distance for each. Numerous charts clearly present the costs, benefits, and trade-offs between both commercial and user-converted models. Key features include: Estimating motor-performance for wind, hill, and cruising power requirements Estimating battery capacity and a thorough description of battery charging Motor and motor-control options Evaluating motor-to-wheel coupling options Placement of propulsion components Configurations and performance How systems-engineering techniques can produce electric-bicycle designs that have long travel range and low life-cycle cost Testing Developments to watch
