DESCRIPTION


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.
