When cornering the tyres are likely to collapse sideways as they have no intact bead or air pressure to keep their shape. The half wheels will shatter soon too because there is nothing to cushion impacts and the structural integrity an intact rim gave them is now absent.
If one broke from hitting a curb they’re brittle as fuck anyway, looks like carbon or possibly even plastic with minimal “spoke” count, how strong does he think just half of one is going to be?
Rearmost half wheel is reversed to align the disc with the chain, meaning the wheel dish will be backward and the centre line off, so handling will be constantly veering off to the side.
And is that one long chain driving both wheels? Better not ever change gear, then.
I hope the 60 seconds worth of riding round the park he got in before the thing broke was worth the hours thrown away on this stupid bullshit. Still, at least he has those all important channel views, on a video which will likely inspire dozens of fuckwits to do something similar and get themselves maimed or killed. Who needs engineers anyway?
edit: Okay so at 5:32 you can see he had to jam something inside the tyres to keep them round. My other comments last night still stand. Massively wasteful, after breaking* one cheap wheel he decides to destroy another plus ruin his bike frame. 43 million views, jesus. I guess the ad revenue is more than enough for a new bike.
* And that was clearly deliberate, it looks like he cut partway through the rim in a few places before filming himself repeatedly slamming it into curbs.

Imagine a non-articulated lorry with an extra pair of non-steering wheels halfway along its length. Every time it went anything other than straight, the middle set would be dragged sideways across the road.
Obviously on this bike with two half wheels, only one rear or the other would be in contact with the road at any given time, but it would still flip back and forth between two different radius turning circles with every half revolution of the wheels. So even keeping your balance while steering would probably be nightmarish.

Bicycles don't have transversely mounted pairs of wheels, so compared to a lorry, any difference in the tracking radius on the extra wheel will be very small. The fact that the bike can be ridden at all means that it will go round corners (you have to be able to lean a bike to balance it) and you can actually see the bike cornering successfully in the video.
I think people are taking this a bit seriously. It's just a bit of fun, not a practical re-engineering of the bicycle!

Fucking HOW MUCH? I wouldn't pay 10 quid for them.

That looks like someone chancing their luck with credulous buyers. Available for £50 elsewhere (although I agree that is still about £40.01 more than they are worth.

It's like an A-Team movie, the plot is full of holes and the contraption is entirely impractical and laughable, but it is entertaining. I enjoyed the strange effect where my brain expected the bike to clunk to a halt, but in fact kept going. It was better than an awful lot of YouTube drivel.
As for the ad revenue, I have heard other YouTubers say they get about $1 for every 1000 views, so 43 million view means a lot more than a new bike. $43K in fact.
