The original “Halo Bike” on Zwift, the Concept ZI is affectionately known as “the Tron bike” (but not called that by Zwift due to copyright concerns). The only way to unlock it is to complete the hidden extra challenge portion of the Climb Mt. Everest challenge: a total of 50,000 meters (164,042′) of climbing!

The Tron is special/unique in lots of ways. Read all about the Tron bike here, learn how to dial in your color slider for a sweet two-tone effect here, and learn how to get a white Tron here.
