How fast is an electric bike?

A well-engineered electric bike has the potential to power you up to high speeds. But how fast it can actually travel isn’t usually determined by its physical capabilities.

The real question isn’t “how fast can an electric bike go”, but “how fast is it allowed to go”. Whereas it’s engineering that determines the former, it’s legal constraints that determine the latter and they vary globally.
