Thanks For Sharing. .Ron .
Neat times,
The five speed works great. The cluster is 14-28 tooth. In first gear 28T you are ready for Mt. Everest. In 5th gear your moving much faster than you should be. Really, all I use are the three mid 3 gears.

I have two other bikes (both 1 speeds). They have good motors and really seem to meet 90% of my riding needs. The 50cc needs a little help on hills but the c-clutch 66cc handles about anything.

I use a 3/4 shaft as that is what came with the $40 shaft/sprockets/bearings pkg. The bearings are 1 3/8 OD. The bearing tube is 1 1/4 black gas pipe. I had to try a few pieces of black pipe berore I got one that fit tight(guess the ID varies a few thousanths).

It really is a simple setup and only the pedaling load goes thru the freewheel.
