1963 Schwinn board track racer

I did use a #35 chain from the engine clutch to the jack shaft input. For the jack shaft output to the rear wheel I used a standard bicycle sprocket for a 410 or Z510 chain. The 9T, 10T, 11T, or 17T sprocket with a 5/8" keyed bore can be purchased though http://www.sickbikeparts.com . For the...

You guys are spot on. I'm planning on making a custom in frame tank this winter. I'm just running the peanut tank though this season. Wisconsin winters are long and boring.

A few pictures from last night.

I went to the Rockerbox bike rally in Milwaukee last weekend. My buddy took these pictures of me riding in. There were a few other motorized bicycles at the show. I was proud to represent with my Rat Rod bikes T-shirt.

Re: The Board Track Racer, Briggs powered---PAINTED!!! Beau, I am very impressed with your crank / jackshaft design. I like to say that making something simple is quite difficult indeed. Your idea of putting your clutch on the jackshaft with the BMX freewheel to the crank is ingenious. You...

Thanks guys. That mule was real fun to engineer and build. It took me about eight months to fabricate. I used 12" motorcycle shocks for the suspension. The engine is a 6.5HP 200cc, electric start, four stroke. Yes, it does have a custom four bar front suspension just like a hot rod. I...

Re: The Board Track Racer, Briggs powered---PAINTED!!! That is one awesome looking machine. I can't wait to see the engine back in it. Great work.

DesignIt, Thanks for the positive feedback. I love your flathead motor as well. I'd love to see a picture of your '29 A coupe. Not that I need any more toys, but I built a half scale M274A military mule to haul my board track racer bicycle. It also works great for hauling kids around. If...

Re: Villiers board tracker VIDEO! I think with an 8HP engine you could probably go as fast as you're proposing. I would calculate this as your top speed at 4,200 rpm, and back derive your other sprockets from there. Again, a 44 or 46 tooth sprocket is standard for a rear wheel. I built a...

Thanks for the positive feedback guys. Keeping the design simple is the hard part. I used an engineering program called SolidWorks to to the 3D CAD modeling, renderings, and blueprints. The hot rod in the background is a 1931 Ford Roadster with a 1939 Flathead V8 motor. My board track...

Re: Villiers board tracker VIDEO! I would reccomend calculating your gear ratio for a top speed you actually want to go at 4,200 rpm. 35 - 40 mph is really fast on a bicycle. With an 8hp engine, you can achieve higher speeds, but I don't think that you want to go as fast as you're proposing...

Re: Villiers board tracker VIDEO! Congratulations! My wife is due with our second little one tomorrow. Kids are a wonderful thing. I still work in my shop, but it's always after 8pm. (After the kid(s) go to bed) So you will still have time to wrench, just not as much time as you used to...

A good Ace or True Value hardware store carries them. They have both metric and standard. The rear frame tubes on my 63 schwinn measured .551" so a 14mm split shaft collar fits perfect. I used split shaft collars for my motor mounts as well. 1.00" for the bottom two mounts, and .625" for the...

Thanks for the positive feedback(s) on the brake bosses. They work great might I add. I've been running them for one season with no issues. The split shaft collars "clamps" hold tight. I've had no issues with them shifting after I installed them. If I had the time to make a good welding...

They are custom fabricated to put modern brakes on a vintage schwinn frame. Here is the construction. The split shafts clamp on the rear of the frame so you do not have to weld them to your frame.

Re: Villiers board tracker VIDEO! No video yet of my board track racer. I've ridden it quite a bit this season though. I'll get some video footage this summer for sure. I have a 1931 Ford model A roadster with a flathead V8. I bought it back in 2005 and did a full mechanical restoration...

Re: Villiers board tracker VIDEO! Yes. You can still run the cent clutch. You will be very happy with the jackshaft. Here are some pictures from my board track racer as of last night. I just finished the primary chain idler and heat shield. DONE! I'm running a 2.5hp 100cc, four stroke...

63 Schwinn 97cc board tracker (idler and heat shield update) Over the last few weeks I finished the exhaust heat shield and primary chain idler. I noticed a huge difference in how smooth the bike transitions from a dead stop, to full clutch engagement, to top speed. Note that I now have a...

Re: Villiers board tracker VIDEO! The jackshaft and proper sprocket ratios will help both your low end torque and top end speed. Right now your motor is not achieving top rpm. You want to dial in your sprocket ratios so that your bike is going 30-35 mph at 4,200 rpm. Right now your bike...
