Sorry, this item is out of stock

10G Multi Speed kit only:   

4G-1B transmission is not included:

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

This add is for those folks who already have an older model 1B trans. and are willing to re-drill 4 mounting holes for a 10 degree down tilt.. Should be done in a machine shop for accuracy. 

If you need a 4G 1B transmission go to the next 10G add which includes a new 8 hole 1B transmission. 

10G  is designed to custom fit the and SkyHawk GT2A or GT2B bike frame.  Allows using bicycle's multi speed gearing to shift engine power curve.  ie:  3 or 5 speed e-bike hub axles work great.  

Do not use a standard bicycle which only allows a 2 pt bracket lock.  A 3 pt. lock is best. 

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.
