Is an e-bike really a bicycle? What about a motorized bicycle? What's the difference between a motorbike and a bicycle with a motor? And, at what point did a bicycle with a motor attached to it become a motorcycle?
That last question certainly would have been relevant, or at least interesting in the first years of the 20th Century. That's when the first "motorcycles" were introduced. More than a century later, they look more like fat-tired "cruiser" bicycles (like the ones Schwinn and Columbia made before the 70s Bike Boom) with motors attached than, say, something one might expect to find in a Harley-Davidson showroom.
Unless it's this Harley:
Although it comes from H-D, it's not called a "Harley." Rather, the company has called it--and the division that will offer it--Serial 1. The machine in the photo is a prototype of what will be available in the Spring of 2021, according to the company.
It's interesting that Harley is going "full circle" in an attempt to renew itself. I can remember when riding a Harley was a sign of marching (OK, riding) to one's own drummer: Think of Wyatt (played by Peter Fonda) and Billy (Dennis Hopper) in Easy Rider. These days, though, the guy perched on a Harley is more likely to be a dentist who's, oh, about my age than a young, footloose rebel. Harley-Davidson sales have been all but nonexistent among millenials and not much better among Generation X.
Could a Harley, rather than a DeLorean, be the vehicle that brings young people back to the future?
