I saw some reports of problems with early production, and that some change was subsequently made by SA: https://www.bikeforums.net/bicycle-mechanics/1117783-s2c-sturmey-archer-2-speed-kickback.html...

Now I know what to do with all those Half wheels I've accumulated.

I put a Yellow Band Bendix on my '73 Speedster, which was originally a single speed. Also added a front brake at that time. It works well and tames the occasional hill around here in mainly flat Chicago. The Bendix Red, Yellow and Blue Band hubs can be found 2nd hand on Ebay, but keep getting...

I worked briefly for a testing company as a summer job years ago. The Magnaflux method relies on the fact that, in ferrous materials, any crack will result in opposite polarity faces on the two sides of the crack, if the material is magnetized. The parts to be tested were subjected to brief...

My brother, who used to be a ham radio operator, told me about this application that lets you stream radio stations from all around the world, called Radio Garden. Just click on any of the green dots that represent radio stations and you can hear what they are broadcasting. Come visit me in...

That's very interesting, especially as compared to the geometry geeks frame drawing. Are frame SIZE dimensions, as cited by manufactures, C/T or C/C for seat tube? It would be cool to be able to superimpose one frame drawing over another. A DXF library maybe? Would you talk about how you...

I think Juicer had the coolest looking design. The batteries ( jumbos too, far more capacity than the little cells that most packs are built from) are arranged to look like the cylinders of a Vee engine. Hiding in plain sight, accessible, but gets that weight down nice and low. I believe...

My Bendix Red Band "Automatic" Hub has 3 stripes. Also, it's physically larger, close to a Sturmey Archer AW 3 Speed hub in diameter. Also, the 18 tooth sprocket is not separable from a major internal component. Also, the coaster brake arm says "Bendix Automatic" Like this: The Bendix RB...

I saw these hubs being offered on Ebay, and I was also interested, but balked at the prospect of not being able to obtain the shift and brake controlling components. I'll be interested to hear what solution you come up with. I noticed that the end-on pictures show that both ends of the axle...

I'd braze that crack with my oxy-acetylene torch and some bronze rod. Much more forgiving than welding, with less chance of blowing through. Could also use silver solder at even lower temperatures. Wire welding seems pretty iffy, but I'm partial to what I'm used to, and have no skill with...

Apparently it's quite different here in Illinois. I found this legal opinion on a law office's site: "...., none of the classes of motorized bicycles requires the operator to hold a driver’s license. In contrast, moped riders must possess a regular Illinois driver’s license to operate a...

I definitely DO want that. The obround shape is very nice, very classy. That's going to look awesome! I'll PM you with my address. Thanks again!

Wow, thanks for the offer. Very generous, that would be great. I could definitely make some struts. I think I have some 3/4 x .090 flat wire that would be just about right for the purpose. No rush, but if you do find it, I'd be happy to offer you some money for your effort.

Thanks for the serial number info, and the clues to telling mileage on the bike. The frame did seem quite light when stripped, and even when fully built, I don't find the bike to be unmanageably heavy. I think you may be right about the bronze color being brazing metal. It does have a very...

Thanks for your responses. I have the bike almost back together and took some more pictures as I reassembled. Any steel structure is a spring of sorts, at least until the elastic limit of the material is reached. Here are some details of the fork design. The struts are solid 3/8" round steel...

My first balloon tire heavyweight, I bought this Hiawatha off Ebay last week. The bearings were stiff and the rear tire wouldn't hold air, so I took it down to bits, to derust, bang out dents, and grease and oil. These pictures are from the seller's auction. I can take more as I reassemble...

I have a project that is going to need a large radius bend. What sort of rigs do folks use? I looked around a little, and I see equipment for bending up roll cages and what not: 3rd Gen Hydraulic Round Tubing Bender & 1 Die Set (speedwaymotors.com) This young man has developed a nice tool...

You mean like the Raleigh Chopper? Pin on Raleigh Chopper (pinterest.com) Seems like the Sting Rays just used the standard Schwinn Cantilever frame, which had been used for decades prior? I consider the "S curved" tube from head to crank to be the weakest element of this frame design...

As a mechanical engineer, I look at those bent tubes and see reduction of load capacity, not necessarily beauty. That frame has a fair amount of extra mass going along for the ride. Form foils function!

Living on the northwest side of Chicago, near Irving Park and Elston Ave, I got back into bicycling a couple of months ago, when a left turning new driver, took out my Royal Enfield motorcycle. Rather than rush into another motorbike, I dug out one of the old classic bikes I'd collected over...
