ok every one heres the rear wheel:

What is the size of the rear wheel on there and what size will the sheath/pulley be on the rear wheel? Do you have a picture of it and could you place it next to the rear wheel to get an idea of size and placement on the rear wheel?

 

[jj256]

the rear wheel is 26" and i have numerous choices in sheath sizes but in between 8" and 24" is the preferred

 

[jj256]

if i were to mount the sheave on to the spokes, how long do i have until the spokes bend

 

[ozzmonaut]

2 things to consider: How tight are your spokes, tighter will keep them from flexing Also the more spokes you mount to, the better it will be, as more spokes will be taking the torque
I would find a tandem rear wheel as it will have the super thick spokes

i see jr. dragsters (run 5 hp engines) but built up, run mid 7's in a 1/8 mile around 75-80 mph

Ok I got my bike running and my final.drive is this: 12 tooth clutch to 15 tooth sprocket on the jackshaft. On the right side of the jackshaft is 3 1/2 front pulley and a 22 inch rear sheave, the power plant is a 7 HP engine and a electric motor, I need a MPH figure I don't know how fast I'm going
