Electric Bicycles

Design or build a battery-powered electric bicycle 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 A comprehensive resource for harnessing innovation, Electric Bicycles is the definitive practical guide to taking full advantage of this exciting alternative energy technology. von Morchin;Oman;
