There's absolutely no practical thinking behind this wacky bicycle, and … that's kind of okay with us. The Trocadero Fixie looks like a regular pushbike until you pull a pin that unlocks the main frame downtube, allowing the bike to twist in the middle and put the wheels wildly out of alignment with one another. Why? Because it looks absolutely bizarre.
The Trocadero Fixie behaves like a regular retro fixie until you uncouple the two halves of the frame, at which point riders are free to throw the rear wheel out at a totally different angle to the front one.
Even with the frame unlocked, it seems it's well enough behaved; the Trocadero team doesn't seem to have any trouble keeping both ends in line when they want to. In fact any back-end shenanigans look very much like a deliberate action.
The twisting frame seems to allow some crazy-tight turning at slow speeds, but looks like it needs a bit of planning and body position forethought at quicker speeds. Check out the video:
So far, Trocadero has only made 30 of these nutty machines – but we can see this being a popular niche fun machine for cyclists with a taste for attention.

It's only fixed gear if it can't freewheel.
