Designers and have released some fancy bicycle concepts lately, like the flying bike, the Porsche 911 bike and BMW folding bike.
Just released by Jeongche Yoon is a fresh fixie concept with Z-shaped frame. The downtube transitions into a seatstay instead of ending at the traditional weld to the bottom bracket. To allow for this, Yoon hollowed the seat tube for the downtube to pass through. A bolt connects the seat tube and downtube for frame stability. On top of the interesting frame design, Z-Fixie rocks an integral tail light, bullhorns, and, for that uber hipster look, non-machined Aerospokes.
Shown above schemed chrome and black, Yoon tossed some red and white into alternate designs after the break…
Yoon describes the bike:
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.
