Z-FIXIE is a fixed-gear bicycle concept with polished Z-shaped frame.
The top tube, the seat tube, the bottom bracket and the chain stays are connected onto the Z-shaped frame.
The down tube and the seat stays straightly cross through the seat tube.
The frame is designed for a simple and urban look meanwhile keeping high stability from traditional bike structure.
It is completely compatible with current components in the market,
and is perfectly harmonized with the integrated rear lamp as well as aero spoke wheels.
