A Berlin inventor has come up with an electric bike which you power by pedalling that can reach speeds of 50 mph.
Stefan Gulas has developed a system that amplifies the effort you put in by a factor of 50, meaning you can accelerate quickly and maintain high speeds with very little effort.

$40,000 - for the prototype ?
That cost could be brought down substantially if it was to be mass manufactured.
