When Harley-Davidson founders first attached a motor to a bicycle frame to create their original motorcycle in 1903, they changed the way the world moved forever.

Fast forward 120 years and Serial 1 Cycles have recombined the freedom & simplicity of a bicycle with the effortless joy of electric power, to change the way we move again.
