16T CVT FREEWHEEL DRIVE SPROCKET and shaft KIT

GruBee Inc

$49.95 

Chain alignment is greatly enhanced with multi-positional sliding sprocket design that can be positioned as required with spacer washers.   

  This 16T Freewheel Conversion Kit can greatly increase your road speed over the old solid 10T or 12T drive sprockets.   

Yes sir! this kit fits our prior model 79cc CVT that we first came out with last year as well as the new shipment just received on Dec 3, 2025. 

The beauty of a freewheel is you can easily pedal your bike with "engine off".   

To install this kit just remove the standard stock drive shaft and solid sprocket and then install this new shaft and 16T Freewheel sprocket with the 4 eared "Slug Plug".   For correct rotation install the 4 eared slug plug with ears facing the 5G  transmission.   

  Slug Plug hole diameter is16.01mm

Only fits our Gru-Bee CVT made for Harbor Freight 79cc Predator engines.  WILL NOT FIT ANY OTHER CVT made by competitors or by COMET.
