Do you want to see how fast a little 53cc HuaSheng non-governed engine can take you on flat land? If so, here's the answer. Just don't take the engine past 6800 rpm and use common sense.

GruBee 10G Multi Speed kit includes a 1B 20T/100T transmission made for the 53cc or 49cc integral centrifugal clutch engine.

10G allows normal bicycle pedaling and also has the benefit of being able to shift gears using engine power like a motorcycle.

Some experimentation with sprocket ratios may be needed to find the sweet pot for your specific riding needs.

Huasheng Engine and bike frame are not included with this 10G kit.

Double U joint Jackshaft drive allows shifting your HS 4 stroke powered bike like a motorcycle!

A 5 or 6 speed Multi-Speed Hub Axle works great. ie: Nexus, Strumey Archer, Shimano, etc. Allows shifting gears at a stop light or on the run. A derailer system does not allow shifting while stationary.

10G was designed for a built-in tank S curve frame pedestal mount to enable having a 3-point lock securement. However, a standard cruiser S frame will work if modified for 3-point attach.

10G cannot be used on a Straight Downtube Frame Bike due to inadequate clearance for the jackshaft at the backside of the engine:

10G Kit INCLUDES:

4G 1B 20T/100T Transmission with 8 mt. holes.
10G Jackshaft Kit with Double Universal Joint 9T drive.
Includes our new upgraded heavy duty double U joint.
10G 3 Pt. attach Engine Bracket is made to fit a built-in tank S curved pedestal mount downtube frame. Available from California sellers.
All Bottom end right side parts are included except for chain and pedals.

BENIFITS:

10G Multi Speed allows you to use a bicycle's rear wheel gears either with a common Shimano detailer multi sprocket cassette or with a Strumey Archer, Shimano or Nexus 3 or 5 speed Multi Speed Hub Axle.
BEST: Use a Multi Speed Sturmey Archer or Shimano Multi Speed Hub axle and shift gears like a motorcycle even while setting at a stop light.
GOOD: Use a 6 or 7 speed Shimano derailer system and get the cheapest set up but can only shift gears when rolling.
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 a jackshaft drive.
A new and improved Needle Bearing Double U Joint Jackshaft drive with needle bearings is now included.
10G Multi Speed kit is Custom Designed to fit built in gas tank S curve frames with mounting pedestal on the downtube, advantage = 3 pt. lock.
Not recommended for a standard bicycle frame. By using a Pedestal Mount frame you get a 3 pt. lock attachment which better controls engine torque and vibration which is a Long Life enhancement.
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 speed Shimano Derailer system. A heavy duty e-Bike 5 speed hub axle which works OK but it's best to use a 22T or bigger Freewheel sprocket on the rear axle hub.
The builder or end user must accept all product liability as you are the prime contractor and vehicle manufacture even if done in your own back yard.
Inspiration and imagination combined with fortitude and ambition must come from you.
Look carefully to know what is NOT included:
NOT INCLUDED; Gt2A / Gt2B Frame or Bicycle:
NOT INCLUDED: Bicycle chain and left and right pedals.
NOT INCLUDED: HuaSheng 142F-1G / 144F-1G engine with centrifugal clutch:
The beautiful Blue bike with the long poo poo pipe shown in attached pics was built by our good friend Mr. Dave Harber in TN.. Shown for illustration only.
If you have any major questions please ask before ordering.

Enjoy a 10G build and ride with the wind using selective speeds!
