The novel contraption replaces the standard rear wheel of the bike with two halves which alternate as you ride along.
Never underestimate the capacity of some YouTubers to go above and beyond when it comes to creating unnecessarily complicated and completely pointless contraptions - as evidenced recently by this bizarre bicycle with two half wheels created by the talented people behind the channel "The Q".
The front half of the bike appears entirely normal, however at the back the rear wheel has been basically split in two, with each half separated so that they touch the ground alternately as it rides along.
Of course this peculiar invention has absolutely no purpose whatsoever other than to be an interesting engineering exercise and to serve as a curiosity worthy of attracting views on YouTube.
It does, however, succeed in both quite admirably.
"I bet you have never seen anything like this and yes, it's fully working bicycle you can ride every day," the video's caption reads.
"This is how regular math looks: 0.5+0.5=1 so, in bikematics it should works as well."
