Look Ma, No Hands!
Good afternoon! I've been bitten by the bug of vintage muscle bikes. I grew up with a Stingray and loved it. Years later I ended up with a bike from an estate sale and now just a few months into messing around with it I now have a 70 Schwinn coaster krate. I really have zero knowledge about krates, but have been reading threads and articles relentlessly. So as for the Krate, I kinda stumbled into it on ebay and bought it. I didnt know that there was even a coaster model, so that's an indication of how new I am to the vintage schwinn thing. According to the serial numbers it was manufactured in October of 1970. there aren't any witness marks to show a shifter mount, but it looks like there was a bendix brake mounted, also from what I can tell the frame resembles the way the coaster versions look. I've been collecting parts that are 1970 specific or vintage so far. Here's the Frame, crank, and chainguard as I bought it.

Thanks for the information on the hub, how many teeth is the rear sprocket supposed to have? I can't seem to find a straight answer. I see stuff ranging from 18-20 in different places.

Welcome! I love the boogie van in your avatar, too! Anyway, anywhere from even 16, 17 to 22 tooth is reasonable - it really just comes down to your preference and riding style. They are easy to swap out and Bendix cogs are readily available.

Lastly, I wonder if your chainguard is from a '99 re-issue? Not a big deal but it doesn't quite look like the 70s one to me.

thanks for responding, I found an 18 tooth bendix 70 that I went ahead and ordered. I'll try that one out and see. I think you're right on the chain guard. One of my friends that's into Krate's said the same thing, I'm going to eventually try and find an original but I want to get the bike together first. As for the S2 rim, were all the Schwinn rims stamped or were there some that weren't? I found a 5 speed rear rim S2 but it's unstamped. Not sure if it's a repop or what.

I think all the S2s were stamped but I could be wrong. Is it knurled? If it has a 5 speed freewheel hub it wouldn't be repop-that's some vintage stuff.
The 70 hub isn't technically factory-correct either so if this wheel's a good price - go for it!

I'm wanting to go factory correct. So what hub is factory correct? here's the pics of the rim. I don't see any knurling.

I don't really see any knurling either. I believe correct would be a side stamped S2 with center knurling but be prepared to pay. Correct hub would be a Bendix red band coaster.

So with the Red Band Bendix, I'm clueless, I see ones with one band, and a coaster and I see ones with three bands and a coaster but it says Automatic. What's that?

My S-2 's are all double knurled, I think some of the later was not stamped. But I'm far from an expert. Keep looking you best bet might be to pay up for a parts donor bike that way you may come up with some nicer parts to swap out. Often guys will go with a Fair lady or slick chick they are easier to find. Do me a favor and send some more pics of frame from different angles if you can. Always glad to help out.

yeah, that's a good idea, what years were the S2's used on the 20" bikes? what in particular on the frame are you trying to look at?

I wanted to know how far the fender/brake mount was from the seat post, If it is only 2 inches that is Jr. frame. If it is 4 inches that is regular frame I was just wondering.

The S-2 were used from the 50's right up untill 82' when they shut down. I have not heard if the quality changed as time went on. Sometimes you can pick upa later 70's early 80's complete bike for real cheap collectors don't seem as high on them and that works out for us.

Well, looking for a Red Band Bendix 28 Spoke again, the sale was cancelled, the seller says they don't have it anymore.
