This clip features a rider piloting a massive custom monowheel vehicle across an expansive paved lot. Resting back in a recumbent seat mounted in front of the huge wheel structure, he controls the machine as its small motor hums with a high-pitched, lawnmower-like buzz throughout. Around the 00:13 mark, the camera pans back to reveal the full scale of the operation, showing him navigating wide turns on what appears to be an old airfield or industrial tarmac with large ships visible docked in the background harbor. Monowheels are always a fascinating glimpse into DIY garage engineering, mostly because mastering stability and steering on a single contact patch is inherently sketchy. Watching this giant treaded monster roll so smoothly looks equal parts impressive and precarious—one sudden stop and you can easily imagine the rider tumbling head over heels inside the frame. It is a neat piece of footage that captures the sheer novelty of custom-built machinery.
