Electric Bike Maintenance Manual

ISBN 978-0-9905228-0-5

Don Gerhardt from Gerhardt Cycles developed a training course for electric bike technicians. The course evolved from an earlier course on the design, assembly and application of lithium batteries. The course material is being used by the Light Electric Vehicle Association (LEVA) for their electric bike technician training and certification program. Over 1000 technicians have received training at various locations including Interbike, Community Colleges, Universities, Park Tool, the United Bicycle Institute and E-Bike Manufacturer headquarters. Each student is provided with a copy of the Electric Bike Maintenance Manual on a USB drive. The manual has 19 chapters on various E-Bike systems and components. The manual also has over 100 appendices with technical service information and videos on diagnostics and battery testing. Contact links are provided for over 500 worldwide manufactures of E-Bikes, E-Scooters and Personal Electric Vehicles.
