I know most guys who frequent this site want to puke at the site of something like this, but I figured I’d share it anyway. I’m a big fan of Schwinn bikes in all forms. I had this Panther frame and chain guard in the weird green metallic color combo and no fork to match. So I hunted and hunted and finally located a chrome Sidewinder fork from @Muleman121. When it arrived, I decided that it belonged on this frame. So here is what it looks like so far. Just need to finish a few things. By the way, this is the frame I had asked for some help on with getting the fork bearing cups to fit tighter in. They were loose and would slide in and out of the frame freely. After more research and lots of questions, I opted for the JB weld method. I am happy to say that it worked like a charm. I spread a thin later on the inside of the frame head tube and let it harden up. Then I sanded it lightly to fit the cups and pressed them in. They are nice and snug in there. At this point I’m looking for the shorter style ballooner guard in the same color or black original worn condition and a bmx stem like the one on the bike now, but with “Schwinn” stamped into the top. I’m also looking for a black 44 or 46 tooth sprocket for use on one piece cranks. So if anyone has either of these, please direct message me. I’ll post a few better pics this weekend when it’s light out. But this should give you the idea.

My projects are all "restore to original" affairs, but it would be fun to let loose and commit blasphemy without worrying about being struck by lightning bolts from the Gods of Restoration. Have been thinking about making a straight bar rat, but don't know enough about the new parts and which modern pieces would fit the old frames.

Here's a sample pic from cyberspace I've been admiring. Looking forward to seeing what you do with the Panther, especially which chain wheel and bottom bracket you go with.

It’s fun. I’d never take a complete bike and stop it down to do this. I had a frame and chainguard and couldn’t find a matching fork. I have no issues personally with building stuff like this when it come from extra parts. I don’t know a lot about the new parts either, but I’m learning. I’m trying to keep as much stuff scheinn or st least sorta period looking as I go. It feels like it’s going to be a comfy bike. Pics will keep coming as I progress.

Normally, I like them stock and original. But all I had was a frame and fork, and the frame has original paint that was too good to sand and repaint. In a way, building this bike up this way is still an effort of preservation. It may not appeal to all, but no harm was done and it looks damn cool and will be a fun rider. And when I have the urge to take on some dirt, I’m still doing it on a vintage Schwinn.

When I had that disasterous NEXT Sierra Key the LBS guy put a REDLINE crank and sprocket on it.

That was somewhere around 2007-8 and the sprocket was covered with a red sticker with the REDLINE logo across the middle. If you can get a Schwinn sprocket on that you should be fine.

I don't think you want a crank like that on that bike anyway, only a hunch.

Most "new" parts will fit (if we're talking 70's-80's bmx cruiser parts.)

I have Araya 7x alloys (26x1.75) and 26x2.3 kenda krad tires on my 48 DX, with a german Durex 135mm coaster brake. Tires fit fine, had to spread the chainstays for the hub (yanked 'em apart by hand,) but everything is straight.

Fenders and chainguard, though, that's another story.

I figure the main reasons klunkers (then and now) didn't run them, was because fenders are heavy, you'll get chunks of mud stuck in them, you'll tweak them when you crash, and changing flats would be a hassle.

Same goes for chainguards. It'll break off, you're cranks don't fit, it'll bend into the chain and sprocket when you crash, and putting your chain back on would be a hassle.

Plus, they (we,) just go for the bare bones necessities. Riding uphill with and added 15lbs is no fun, and carrying broken parts down a mountain would suck, too.

Chainguard should work fine with 3 piece type cranks, and I’ve never had an issue with it on all the fireroads and trails I take my 40 tallboy on. I got tired of breaking one piece bmx cranks out in the boonies and finally went with the 3 piece. These bikes are capable of much more than you might expect.
