BENIFITS: 

  • 10G Multi Speed allows you to use a bicycle's rear wheel gears either with a Shimano detailer multi sprocket system or with a 3 or 5 speed Multi Speed Hub Axle .   

  • Use a Multi Speed Sturmey Archer or Shimano Multi Speed Hub axle and shift gears like a motorcycle even if you're setting at a stop light.    

  •  Use a 6 or 7 speed Shimano derailer system and get the cheaper set up. .  

  • Installation does require basic mechanical aptitude and basic shop tools along with possible field modifications and misc. small parts obtained locally.  ie; Chain and or pedals.

 Most everything special you need is included except a SkyHawk Gt2A or GT2B bike frame with built in gas tank and a HuaSheng 49cc or 53cc 4 stroke engine with integral built in 3 shoe centrifugal clutch!    

  • Our late model 4G 1B Transmissions now have 8 holes for a 10 degree tilt which is necessary to use the 10G jackshaft drive.

  • 10G Multi Speed kit is Custom Designed to fit either our Skyhawk Gt2A or GT2B built in gas tank frames  advantage = 3 pt. lock.

  • If you have an early Gt2A frame with a big bottom hole then you will need to use the included WP-CK conversion kit.   GT2B frames have a small bottom hole for a 3 piece pedal crank system. 

  • 10G works well with either a 3 or 5 speed Nexus or Shimano rear wheel hub transmission or can also use a 6 multi speed Shimano Derailer system.  A heavy duty e-Bike 5 speed hub axle which works best.
