Unknown LV3 Purple Chameleon | Fixed Gear Track Bike

Signature Track Frame — Purple Chameleon Edition

The Unknown LV3 Purple Chameleon is our flagship fixed gear bike in a head-turning purple chameleon finish that shifts between deep violet and blue in changing light. Same race-proven LV3 platform — hardened 6066-T6 aluminum frame, aggressive track geometry, and just 8kg in size M.

Performance Components

The LV3 is fully equipped with Unknown-designed components built for serious fixed gear riding. The full 12K carbon fork delivers precise handling and vibration dampening that you will feel from the first ride. Sealed-bearing Mushroom hub wheelset with Japanese bearings ensures effortless rolling, while the 46t/17t gear ratio is perfectly balanced for city streets and velodrome sessions.

Carbon Fork

All European LV3 builds come with the full carbon fork as standard — a significant step up from alloy in both ride quality and aesthetics.
