Fixed Gear Bikes

Explore the complete range of Unknown fixed gear bikes. From the 4130 chromoly SC-1 to the LV3 track bike with its full 12K carbon fork, there is a model for city riding, training and track-inspired builds.

Unknown complete bikes use 6066-T6 aluminium (LV3, Singularity, Bass-X and Paradigm), 6061-T6 aluminium (PS1) or 4130 chromoly steel (SC-1) frames. Every current complete bike has a flip-flop rear hub with a fixed cog and an included single-speed freewheel, so you can ride fixed gear or single speed, and front and rear brakes come fitted.

Our bicycles arrive approximately 90% pre-assembled, with free pedals and foot straps included. We recommend professional assembly by a qualified bicycle shop.
