Nothing terribly exciting, as I'm planning to take this bike back to a relatively original state, but thought I'd post some pics. I got the itch to own a bicycle after getting my 3-year-old a bike for Christmas. A few weeks ago I bought my wife a big-box Huffy cruiser, and then started thinking about the kind of bike I wanted. Being an engineer by trade and a tinkerer at heart, I could not bring myself to own just any ordinary bicycle. The Swingbike was about the most outlandish thing with two wheels and a set of pedals I had ever heard of, so I had to have one. This is probably my first bicycle in 20 years, and my first time building/restoring one. For what looks like such a simple craft on the surface, there are lots of details and terminology to bicycles...I'm still learning a lot!

Anyhow, I initially thought I would build one after reading this. I bought a rear-triangle from the 2003 run on eBay and started trying to reverse engineer the "swing frame" from pictures I found on the web. I bought a bike to sacrifice for the head tube, was looking for a second, and had a guy with a tubing roller lined up to bend me some cross tubes. Then I found a Swingbike on eBay and decided to just buy that and restore it. I'm not yet sure what I'll do with the rear triangle and extra bike parts I have. Anyhow, onto the pictures.

Here is a picture of the model I made of the "swing frame". All measurements were taken from a few internet pictures and averaged. I'm curious to measure the real thing and see how close I was.

Here is the bike I was going to chop up and use. It's a 1979 Schwinn Collegiate 3 I got on CL. The angle of the cross tubes and the head tube looked like it would work good as the front headset on the Swingbike. Not sure what I'll do with it now.

Here is the Swingbike I bought on eBay, just after unboxing it.

And here it is assembled. The tires were so dry-rotten I blew the rear trying to ride it around. It was originally blue, and then someone painted over it a lighter blue. Rusty chrome, wrong parts everywhere, missing parts...it truly is a project!

I got it taken all apart this weekend and dropped the frame off at the powdercoat shop this morning. It's going to be yellow when I get it back.

Lots of parts still rolling in through the mail for this build. Looking forward to getting it completed and turning some heads when I ride around downtown Chatt this spring and summer!
 
Will be looking forward to your build, and also to see if you have found any good source for a rear rim, fenders, or a sissy bar....I might have some spare wheel reflectors, interested in your spare triangle if you decide to sell it. (once work starts up again and I have $$)
After riding mine I think I will be building a larger version eventually.....but it still is a ton of fun. Be careful out there and don't try any goofy tricks until you are really confident with it...
 
My search for fenders and the correct sissy bar have fallen short, so far. I'd love to find a set of good condition fenders. I am picking up a used vintage sissy bar from Ichi Bike that is cleaner than the one that came on the bike, but the longest distance between holes is 19". The one on the bike is kind of rusty and the hole distance ranges from 19.5" - 22". Hope the newer one will work. For wheels I just bought a set of 99 Krate wheels with the Slik...really hoping those will fit.

Yeah, I think I'm going to take it slow, especially after having the frame powder coated and putting all these new parts on it...I don't want to bang up the bike (or myself) after getting it looking good! I'll keep you posted on what I decide to do with the spare triangle.
 
DJ Bill, my Swingbike came with the wrong rear wheel - it's a black rim and has red writing on it that says Gravity Games. Or were you talking about the Krate repro wheel?
 
I was hoping yours came with the right one.. Oh well. I think the one that came with mine could be an original but I dunno. The one mounted up in my avatar is an alloy BMX wheel, not correct but it works.
 
The Swingbike came with the wrong rear wheel, and it had a 16-tooth rear sprocket on it. My replacement rear wheel has a 20-tooth sprocket on it. The chain wheel that came on the bike is 40-tooth. I'm debating on whether or not to keep the 40-tooth chain wheel or switching to a 36-tooth Schwinn Lucky Seven sprocket.

Here's my questions:

1 - Would going from a 40T/16T ratio as it came to me to a 36T/20T ratio just be a bad idea, or is this not too close of a gearing? I'm not going to be doing any long distance riding on this, just cruising around downtown with it. Not sure if for this type of riding that these ratios are even an issue.

2 - Regardless of which ratio I choose - 40T/20T or 36T/20T - will I need to change the length of my chain? If so, should I invest in a chain-breaker tool?
 
Great project. If it's not to late, you may want to wait until you get all of the parts and do a dry run assembly before starting with paint. Nothing worse than having to grind or force fit with final paint.
 
I would think the 40/20 ratio would be better, 36/20 is very low, especially on a 20" wheeled bike. A chain tool is a wise investment if you plan on doing anything with bikes, makes things so much easier and much better for the chain...

Luke - thanks for that. I figured a chain breaker would be a good investment, so I may look into getting one of those. I'll just stick with the 40T/20T setup initially and see how I like it. Is it even possible to change the rear sprocket for a different ratio without changing the rear wheel? Maybe something I would think about doing down the road.
 
Yes, different size rears are redily available, looks like it is coaster brake? If so you will find the sprocket is held on by a circular clip, simply a matter of removing that and sliding the old one off.

Cool, I'll look at it tonight when I get home. Yes, the new wheel has a coaster brake, the old one was no brake. Thanks for the tips.
 
Ok, color they used and cost of the powdercoat? (If you don't mind...) I've got a couple possible powdercoat projects and looking for ballpark figures.

Nice, you don't have to wait till it cures, that killed me on my Roadmaster to wait..
