What is a characteristic of an electric bicycle?

An electric bicycle is characterized by having fully operable pedals along with an electric motor. This combination allows the rider to use either the pedals for traditional cycling or the electric motor for assistance, providing flexibility in how the bicycle is used. The presence of pedals is crucial because it distinguishes electric bicycles from motorized vehicles, ensuring they can be ridden in a manner similar to standard bicycles.

While other options mention features that may apply to different categories of vehicles, they do not accurately define what constitutes an electric bicycle. For example, stating that it has no pedals would exclude it from being classified as a bicycle, and suggesting it can reach speeds of up to 40 miles per hour misrepresents typical electric bicycle specifications, as most are designed for lower speeds to ensure safety and compliance with cycling laws. Calling it a motor vehicle designed for highways indicates a different category altogether, as electric bicycles are typically intended for bike paths and roads rather than motor vehicle lanes.
