Hubless motorcycle with airplane engine - video

[Frank S]

Do you think that is actually (and legally) on a public road? I thought it might be on a drag racing track at first. Could the background be faked? Not many bystanders stopping and staring, as I would!

As far as actually on a public road. YES. Legally though for the photo shoot and video I would imagine would have been some permitting and arrangements which had to be met. for traffic control. If you run the video at its slowest setting, you can see that almost all of the few bystanders were mesmerized as he drove by.
Here are a couple a rabbit hole links of the man's designs.
