Unknown Bikes Fixed Gear Bike Singularity – Army Green

We just received the newest TFGS exclusive Unknown Singularity in Army Green, this color combination is only available here The Fixed Gear Shop

* black/tan wall tires are not included unless selected above

The Unknown Bike Singularity is the evolution of the popular fixed gear LV2 frame, and now it is available as a complete bike. The Singularity incorporates a modern tube set along with an update geometry to be the ultimate race machine. This track oriented frame now includes an integrated aero seatpost and carbon /alloy fork along with other quality components. This is a huge step for Unknown Bikes… and you.

We also opted for the carbon/alloy fork instead of the standard alloy fork for the European market. This fork increases the price a bit, but it makes a big difference in performance and comfort, not to mention improving the overall look!

Complete fixed gear bike is shipped with dropbars and brakes.

Available in following colors: Black,  Army Green, Pink, White and Red

Unknown Bikes Europe is the official source of Unknown Bikes frames and components for fixed gear riders throughout Europe.

A bike mechanic would describe a fixed gear bike as a bicycle with no gear shifting or free-wheel capability.  The bikes you are likely accustomed to are built with multiple gears and a mechanism that allows the rotation of the pedals and wheels to uncouple, which allows you to coast or rest your legs on the flats or downhills.  While these advancements have provided convenience and ease of riding, for many riders something has clearly been lost in this evolution of the bicycle.  This is partly why fixed gear bikes remain the standard in track cycling where they provide optimal pedaling for the flat, high speed race conditions.


The Unknown Bike design combines high performance and quality with a sharp, modern, and no-frills minimalist look.  We encourage you to check out our selection of bikes, parts, and accessories.  As the premiere Unknown Bike source for all of Europe our mission is to fuel the growth of the fixed gear scene throughout this continent.  We look forward to connecting with interested riders and collaborating with top riders enthusiastic to help spread the fixie movement.
