Jason Momoa has converted 100-year-old Harley-Davidson motorcycles into hybrid or electric vehicles, with some reports specifying plug-in hybrids. The conversions involved vintage bikes from the 1920s, and at least one outlet suggests that a company called Electrogenic was involved in the process. The extent to which the bikes were modified and the exact nature of the conversions is not entirely clear, with some reports mentioning electric power and others specifying hybrid systems.
