Rustoration 2.0

if i can find a frame for my liking ill have to get down on thius build off, but unfortunately, it can be difficult to find a decent enough old frame. I too have no shop, u use my bike trailer and the kitchen for my projects. now its time to find a frame.......
 
Corgi,
You were right in having me check the wheel diameter. Mopeds are measured differently than bicycles. The 16" on this moped is rim size. The whole wheel with tires is a little over 20" which changes things, doesn't it? Looks a little more promising. Might turn into a cool bike.

yes that would mean if the 26 inch bike went 36 mph ,then the one with a 20 inch wheel bike should go about 27 mph at the same motor rpms w/the same rear sproket size
the 20 inch wheel travels about 62 1/2 niches and the 26 inch wheel travels about 81 1/2 inches or the 20 inch travels about 3/4 the travel per revolution,or forward speed xct2

The stock kit sprocket is 44T and I did some measuring and it looks like I could cut out the center to a 5" diameter hole to fit over the hub. Then I'd need to make new rag joint backing plates to match. At least is it possible and would give a good cruising speed of 20 mph and wind it out a bit to 25 or so. I would think it would also be pretty good on hills. The other possibility is if I can take the hub plate off and find a way to mount a sprocket directly to the hub. Then a 36T might work. I could find a 36T sprocket on a kid's bike. At least I know now that this is possible. Of course another option would be a ready made moped wheel either 16 or 17 inch with a sprocket already there. Even if it was the wrong size, it would have been made to accommodate a sprocket, so there would be a way to adapt another sprocket. I think I'm going to take the moped with me when I go east and put it together over the winter along with a more serious build, another Greyhound/Schwinn. Thanks, Gene.

36 tooth would bring the 20 inch bike to about the speed of a 26 inch bike w/a 48 tooth


crank sprokets on some road bikes have large center holes and 5 mounting holes(I got a box full of them w/various tooth counts from a lucky(?) garage sale)(mostly aluminin I think ,a few steel ones)
 
i dunno if i'm gonna motorize this, but here's my next project.

an ultra-rare, 24", late 30's Colson Double Bar Jr.

all i need are some 24" drop-center rims and i can ride it. restoring it's a whole 'nother story.

check the awesome rear drop-outs...

instead of being flat all the way across, the center of the wheel has a hump in it, or if you're looking at the rim with the tire off, the center drops in, like a valley.

with all your old bikes, you've probably had a set.

wait, i found a pic:

they came in all sizes. Lobdell was a big name back then.

that style is still made today. in fact, almost all aluminum rims are drop center, only they're squared off.

there's a bike swap meet tomorrow (wait, it's today. i gotta go to bed:)) so i'll probably find some there.

thanks for the offer though...
