Sick Bike Parts Shift kit

 
 

Shifter kit for standard Chinese 2 Stroke

bicycle engine.

This kit will fit almost any Chinese 2 Stroke and

allow the user to shift gears using the bikes

standard rear derailleur.

It will also allow the use an internal rear hub

transmission or the new ultimate NuVinci hub.

The secret is the front freewheel allowing you to

still pedal the bike normally and yet start the bike

with the pedals and not have to pedal the same

speed once the motor starts.

 

The kit comes with everything you need.

1. Cranks, spindle, front freewheel, dual

sprocket and chain-ring assembly.

2. Jackshaft mounting plates including

bearings, axle, sprockets, chain and mounting

hardware.

3. Rear motor mount including all hardware

The gearing will depend on your rear

transmission assembly but typically you will see

ratios between 5.8 to 1 and 2.7 to 1. This is like

running a 58 tooth rear sprocket in the stock set

up all the way down to a 27 tooth. This will allow

you to climb the steepest hills and still hit top

speeds in excess of 40 mph without straining

your engine.
