Unknown LV3 Black Chameleon | Fixed Gear Track Bike

Signature Track Frame — Black Chameleon Edition

The Unknown LV3 Black Chameleon is our flagship fixed gear bike, wrapped in a striking chameleon finish that shifts between black, green, and blue depending on the light. Built around a hardened 6066-T6 aluminum frame with aero-inspired track geometry, the LV3 delivers race-level stiffness at just 8kg in size M.

Performance Components

Every component is purpose-built by Unknown for fixed gear riding. The full 12K carbon fork with 30mm rake provides razor-sharp steering and absorbs road vibration — a major upgrade over standard alloy forks. The sealed-bearing Mushroom hub wheelset rolls ultra-smooth thanks to high-grade Japanese bearings, and the 46t/17t gearing gives you an ideal ratio for mixed urban and track riding.

Carbon Fork

The European edition comes standard with our full carbon fork instead of the alloy version. It makes a real difference in performance, comfort, and looks — well worth the upgrade.

What's Included

LV3 is shipped with drop bars, brakes, and free pedals with foot straps worth €50 included. Ready to ride out of the box.

Weight: 8 kg in size M (without pedals)
