What are the disadvantages of e-bikes?
Maintenance and repair costs. Electric bicycles require regular maintenance to ensure they work properly. Electronic components and batteries can be expensive to maintain and repair. Battery failures, motor problems and repairs to electronic control systems can represent significant additional expenses. The battery is the energy source that powers an electric bicycle and is typically the most expensive part of an ebike system. In the early days of ebikes most batteries were lead acid, nickel cadmium, or nimh, but modern ebike batteries are almost exclusively lithium-ion.
