I think you missed my point Uncle Stretch, Im not doubting your talents, you've made it quite clear on numerous occasions during this post just how talented you are :D I simply meant that stretching a frame isn't as easy cutting a piece of tubing and welding it, and making a motorized bike...

The reason is the style of bike most popular is the "boardtrack racer" or similar bike from that era which is closely related to a bicycle. And one of those engines just do not do justice to that style build. I've always had a fascination with those early motorcycles but could never afford a...

The hardest part of it was drilling into the Stainless Steel brackets, as I said I get it for free from work but have trouble getting mild steel, so I used the S/S, but it isn't necessary. You will find mild steel 100 x easier to work with.

But NO, I didn't at any point fix the sheave to the spokes. I believe I bolted a few brackets to the sheave and to the rear wheel, then added the rest. But I didn't do the final tightening until all brackets were in place. It's a fiddly job but not really very hard.

I measured my rear wheel diameter, and also measured the sheave. Half of the difference in the diameters will be the height of the brackets. (Remember when folding metal to allow for thickness of material) It really wasn't all that hard to do, then I simply tightened the bolts on the sheaves in...

Good point Murray.... Yes I widened my rear fork section to accommodate my sheave, but that has as much to do with how I positioned the jackshaft. I can't see any reason why you couldn't position the sheave with brackets without widening the rear fork.

I'm replying to Stocksucks questions on another thread so not to hijack thread. You asked about me bolting my sheave to the rear wheel via brackets, you asked if alignment was a problem, and also if the bolts damage the tube. I made sure all my brackets were identical and I had no problem...

I will reply on your thread so not to hijack thread.

Cant you get a Whizzer kit? But i must ask, why is it you want to attatch your sheave (rim) to the spokes? I found it a lot easier and a helluva lot stronger to make brackets to bolt the sheave directly to my rim. A lot stronger and you can keep the correct tension on the spokes.....That is how...

Re: 50's Schwinn Rat-Rod Boardtracker Sounds like a cool build. How come i cant view the photos? Are they visible to anyone else? :cry:

Chinagirls dont really have the HP or torque to successfully use on a bike without pedals, especially something as heavy as a Stingray. You will be thoroughly dissapointed with the outcome IMO.

My bike was built on a shoestring budget also, but I still took time and listened to some good advice and I now have a bike that has been safe and trouble free. I don't want to talk for Beau but I'm fairly certain he built his bike on a budget also. And generally fixing mistakes will cost you...

I noticed you were giving him advice that could save his life, he seems to just ignore it???? Oh well, we tried!!!!!!

What you are saying doesn't make sense, yes CORRECT your bike is setup for high speeds at a low RPM. I'm just wondering who will drive your tow vehicle everytime you need to take off :-)

Re: 50's Schwinn Rat-Rod Boardtracker They arent showing up on my end

Re: 50's Schwinn Rat-Rod Boardtracker Hey Rollin, where have all the pics gone????

Re: 50's Schwinn Rat-Rod Boardtracker Beau, ive currently found 3 x 23" XL wheels with the intention of building up a set of wheels. The only problem is tyre selection. I went with Bridgestone TW9 tyres although they arent cheap, but havent gone any further to build the wheels. Since buying...

Im fairly certain your gearing is too high, your primary jackshaft sprocket should be smaller then the engine pulley, they appear to be the same size which means you are relying only on your secondary drive for reduction. A bigger primary jackshaft sprocket (and possibly smaller secondary...

The law in Queensland (The state i live in) says Internal Combustion Engines (ICE) are illegal, i believe New South Wales (next state over) can have ICE bikes but they must remain under 200 watts (our previous laws and totally unrealistic). Correct me if im wrong but an engine running on...

I dont believe propane engines are exempt, but i like your way of thinking. I wouldnt know where to start on the conversion. .................................. I took my bike to Greazefest, which is a ratrod style car show. It was received very well and i had man offers to buy it. It was a...
