I don't know if it's proper etiquette, but I'm puttin' a motor on this Schwinn. I live in pretty lumpy part of the world where a single speed Cruiser just isn't practical. For pedal work/exercise I use a cheap 29" Chinese bike from Wal-Mart. Judging by the tires, tubes, and brake pads on the POS I don't think the design life was more than 500 miles, but I've kept it going. I just wore out my 1st set of Schwalbe Rob Roy's. I'm getting what I need out of it.
But I'm knocking on 68 trips around the sun and have no idea how long I'll be able to continue pedaling. But I also have this need to be on 2 wheels, and that's where the motorized Schwinn is gonna fit. If I can get up and walk to the bike I'll still be able to ride. Hopefully I'll still be buzzin' around town at 82 .....
So here's the general idea ... and what little boy didn't want to put a motor on his bicycle? It just took me 6 decades to learn how to do it.
49cc's of a Chinese 2-stroke tool motor designed for leaf blowers, chain saws, etc. Commonly found in pocket bikes. With modification it might be good for all of 3 hp. Uncontrolled wheelies won't be a problem ...
Brakes could be tho! Depending on gearing it might go 35mph and a coaster brake wasn't designed for that. So I mounted up some hydraulic discs which is a lot easier to type than to do. Here's the front.
Needing a sprocket on the left side for the motor the rear caliper wound up on the right and below the rotor. I had no idea that was gonna happen when I started. The other thing going on in the back is when you put a vibrator(motor) on bicycle the frames have a tendency to crack at the chainstay. My solution to that was to chop the dropouts off and fabricate some nice thick horizontals.
That extra bit of slotting on the bottom is so the caliper mount (not made at that time) can follow the rotor which follows the axle which tensions the chain ...
The rear hub was an issue in that I needed a rotor, freewheel,and a sprocket all on the same hub. But I like a challenge and I own a lathe, so I made both hubs myself. Here's the rear.
That hub is my personal record for the most cuts ever inflicted on a single piece of metal.
Funny story on the spoke circle. 36 spokes. 360 degrees. 10 degrees a spoke. Right? NO you dummy! There's only 18 on each side. I made a few lovely pieces of scrap along the way.
I recently had it up to pedal status but it's apart now for paint.
So what I need to learn about now is how to get some bling on the bars. Restore a seat. Cranks etc. From what I've been reading this is the place to do that.
Thanx for looking and one more detail. It's got dual exhaust!
