I'm using a cantilever frame that has gone through several incarnations. First as a single speed. I got it (just the frame) years back and converted it to a 21 speed mountain bike. I welded rear brake bosses for cantilever brakes so now it is going into it's next incarnation. I stripped the paint and repainted it flat olive with a rat rod/steam punk idea. (wait till you see the exhaust). It is a good quality frame as the rear drop outs are welded to the chain stays, not press fitted like old cheap Huffys.
So I like to fabricate and do my own thing. Saw the Harbor Freight 2.5 HP greyhound engine and knew I had to put it on my bike.
I ordered the left side sprocket from sick bike and a rear wheel with 8 gauge spokes from the local bike shop. Each pay day comes a little closer to the finished project. Tractor Supply Store provided #40 chain and some sprockets. A jackshaft I found on line and a #40 chain centrifugal clutch from a local go cart supplier. The bearings that came with it are junk so I ordered top quality high center height pillow block bearings from the Big Bearing store http://www.thebigbearingstore.com/servlet/the-2163/3-fdsh-4"-High-Centerheight-Pillow/Detail
The motor mounts are fabricated from pre-drilled "hobby" angle iron and some U bolts. The chain tensioner will be fabricated from a #40 idler (Tractor Supply) and some more hobby angle. I plan on having an extra sprocket on the jack shaft so I can quickly move the sprockets over and place the chain on a different sprocket and have a dual range transmission. RST front suspension fork and some good quality kevlar lined road tires should round out the rest...BTW the exhaust system is from Tractor Supply...3/4 inch black water pipe! Photos to come as I have a hard time downloading with the slow dial-up connection.
