10G Multi-Speed Shift Kit and 1B-4G Transmission

10G Multi Speed kit and 4G-1B Transmission:   

Best used with a Multi-Speed Hub Axle

NOTE:  4G-1B 8-hole transmission is included:   

Shift your motorized bike like a motorcycle!  Can even shift while stationary if a Multi Speed Hub axle is used.

10G  is designed to custom fit built-in-gas-tank bike frames with pedestal mount on the downtube.

10G kit allows using bicycle's multi speed gearing to shift the engine's power curve.  ie:  3 or 5 speed e-bike hub axles work great but can also use a multi-speed derailer system. 

A standard bicycle which only allows for a 2 point attach engine bracket is not recommended.  A 3 pt. lock is best like when using the built in tank frame. 

Mechanical aptitude and tools are needed,.  Engineering degree not required but helpful.

     This 10G Kit has been Up Graded: 

    Our current 10G Multi-Speed KIT now has a larger Double Universal Joint with needle bearings versus a smaller one of less durability as was found in initial early production.  

    This 2017 new DUJ is Definitely a remarkable heavy duty improvement and of course higher priced.
