The NASA lunar e-bike prototype was said to be developed in the event of the lunar rover vehicle not being ready for the Apollo missions of 1972 and 1973. The moon scooter didn’t need to be deployed because the lunar rover hit its intended completion deadline. It would take a few years for earth-bound e-bikes to catch up to the lunar bike, but I guess there is one larger trend that can be accredited to this NASA research: hard-shell bicycle helmets.
