How about a nutter cyclist or two?
Around my parents way there’s a guy who uses (excuse my ignorance) a bike that your legs are in front of you. He has paddles attached to the side and uses his arms to proper the bike. He always wears a face mask and wears a bandana, cycles down the middle of the road and shouts swear words at all cars.
When I was a student used to see a local cycling window cleaner ( had a trolley on the back of the bike). Also dressed in day glow lumi clothes, head to toe. Had a lumi bike too iirc. 8)
