Another Schwinn Chopper build

So far I've picked up a BMI peanut tank, Kalloy seat-post and a saddle and added a left-hand freewheel to the rear wheel and made use of the OEM 44t chainring. A full-coverage OEM rear-fender is in the mail as is a Hayes V9 9" brake rotor for the front.

The rotor is gonna be a bit tricky since the front fork on these things comes down where the rotor needs to be. I'm not gonna be able to simply build a disc-brake wheel to suit my needs like I did with my cruiser, I'm going to have to modify the OEM hub to accommodate a rotor while maintaining clearance with the fork.

looks cool already. how do these bikes fit an adult? I'm considering one for my next build.

The OEM saddle is the biggest problem. Once you get rid of that, you free up a ton of leg room. I'm also going to run shorter cranks, probably 130mm, which will give me even more room and allow me to run a pull-start without any problems with interference.

Hi Mike, I was wondering if the sadle came from the same place as the post? It looks a lot comfyer than the stock one I have. Mine is electric, or will be when done. You can get premade wheels with brake rotor mounts from Choppers.us http://www.choppersus.com/store/
My question is how are you gonna mount the caliper?

No, I didn't get them at the same place. The saddle is actually just an OEM Huffy Panama Jack saddle. Cionlli makes a pretty comfy and attractive cruiser-style saddle, I'd check them out first. The post I found on ebay, it's a 31.8mm post.

About mounting the rotor: it's not that I need a wheel built, it's that disc-brake hubs are a standard distance from the jam-nut on the axle and the forks on these bikes are non-standard and interfere with the rotor. The fork ends are on-center with the fork tubes instead of on the inside tangent and you lose about 1/2" of clearance on each side of the wheel. If you're thinking about going disc-brake on the front, please be aware that a standard disc-brake hub will not work. I will take some pictures when I get home from work.

No need for pics man, I got two of em in my living room. One is stock, the other is being converted to electric power. My build thread on ES.

I'm having a locan machine shop mill a mount for a caliper on the rear end. But these seats are murder on my arse. Plus the Spoiler one is so hard to find, that it should be replaced just to keep it safe. Peace, and Happy Thanksgiving.

I forgot to reply to your other question about mounting the caliper:
I myself am a machinist and make my brackets. I have coworkers weld them to the forks. Peace and happy holidays to you also.

yeah the oem seat is terrible for an adult.
That seat pushes you up and forward towards the handlebars.
I put a standard 10 speed seat on mine and modified the mountin so that the back of the seat almost touches the rear fender.
I have the seat down as low as it can go so that it sits right on top of the frame.
it looks so much better and is a lot more comfy.
I'm 5' 6" and weight 150, and i can ride my occ all day long.

I have seen builders mount a bannana seat and sissy bar on the OCC Schwinn to make the fit an adult better.

I ordered a butt-load of parts and FINALLY they started showing up. Well, one part anyways. 16" motorcycle tires fit mint on these rims, I couldn't believe it. Since it fit so well I think I'm going to get a real nice tire, not just this cheapo no-name. I'm thinking maybe a Bridgstone Battlax 130/70-16. I'm still not quite sure what I'm doing for front but most likely a Nirve Bada$$.
