Ukrainian YouTuber Sergeii Gordieiev (aka The Q) has built yet another absurd bicycle—this time, one with a rear wheel sliced in half. The result? A bizarre but functional ride that looks like it defies physics as it rolls down the street.
Gordieiev is no stranger to engineering weird bikes. His past creations include:
- Giant circular saw blade wheels (ridden on a frozen lake)
- Shoe-studded wheels on poles
- A hubless bike
- A chainless bevel-gear drivetrain
- Shock-absorbing wheel spokes
- DIY airless PVC tires
Now, he’s taken things even further by splitting the rear wheel into two offset halves, forcing him to extend the bike’s frame with an extra rear triangle.
How the Heck Does It Work?
Building this monstrosity wasn’t simple. Here’s how Gordieiev pulled it off:
- Cut two rear rims nearly in half, preserving the hubs.
- Modified tires to fit, using PVC piping to recreate the inner tube.
- Reinstalled the disc brake and rear sprocket on the first half-wheel.
- Welded an extended rear triangle to mount the second half-wheel.
- Synced the two halves with a secondary chain, ensuring one half is always touching the ground while the other lifts.
The final product is a bike that somehow rides smoothly—though hitting a curb now delivers three jolts instead of two.
Why? Because Why Not.
There’s no practical reason for this design—just pure, unhinged creativity. And on that front, The Q has once again outdone himself.
