Few people have asked about the wheels on the ST and CF so thought i would put this bit together.
Some of the 3 and 4 spoke wheels i have for some of the bikes i'm building.

4 spoke wheels.
4 spoke front.
The 4 spoke was used on the ST50/70 in both 6v and 12v and the CF50/70 only in 6v.
Brake side,note the plate is on the left side and has screw on speedo cable.

Rims.
4 spoke.
These have 4 smaller 6mm holes and 4 8mm holes.
Image
There is only one bolt hole between the spoke webs.
Image

3 spoke.
These have 6 6mm holes and 3 8mm holes.
Image
There are two 6mm holes between the spoke webs.
Image

Hub nuts and bolts.
The bolts are stock 8mm type but the nuts are a larger size than a stock 8mm nut.
Best to save the old nuts and have them replated.
Small size nut over the larger type.
Image

Smaller stock nut in the larger hole that the hub nuts fits in.
