The FX-FR8 hub – fast urban – concept bike.
A new multi speed transmission based on the FX-FR single speed hub.
The FX-FR8 introduces a new 8 speed transmission that allows the rider to switch between a freewheel ride ( default state ) and a fixed wheel state ( engaged state ) via a dual levered handlebar lever.
A custom frame design fitted with a rear facing stirrup derailleur and a chain tensioning swing arm pivoting around the bottom bracket shell.
This forms a chain loop that rides like a regular derailleur transmission and enables the FX-FR8 hub to freewheel or fix.
