Stuffing a CR250 engine into a bicycle-like frame — that's about as free as a builder's imagination gets. This is exactly why I keep saying a motorcycle is culture, not just a vehicle. Category boundaries don't mean anything to a real builder. Makes you want to peek inside Theo Niess's head.

Is 'hyperbike' an actual official category name?

A one-off build like this must have cost a serious amount to produce.

This kind of experimental custom always ends up breaking existing genre boundaries.

Curious about the structure of how they fit a CR250 engine into a bicycle frame.

'A custom that dissolves boundaries' is exactly the right phrase for such an original build.

Putting a motocrosser engine into a bicycle frame — the sheer freedom of the idea is fantastic.

The visual impact is huge, but I'm curious whether it's actually street-legal spec.
