my 20 inch 1967 simpson sears bike build
Well here it is my most recent bike build.the bike frame it's self is 20 inches in size and as far as i reserched it it's dated back from 1967. Found it being thrown out in the trash and saw the potential of it so i went about restoring it as well as motorizing it.As you can see it's a real tight fit for the chris hill ch 80 motor.In the last pic i custom cut the 2 outer chain rings off so that the most inner 28 tooth sprocket would fit under the motor.tell me what you think guy's.

Re: my 20 inch 1967 simpson sears bike build
Here's what it look's like after the restoration and motorizing the bike was done. Yuo can see how tight the fit of the motor was ,because i had to put the carb on the out sideof the frame. The peddles are so low to the ground that they can be used as kick stands them selves.The speedometer came from an exersize bike as well as the seat. Tell me what you think because i think it's cool looking as it is to ride.

Re: my 20 inch 1967 simpson sears bike build
looks sweet. Only things i would change would be the handle bars (ape hangers) and tires ( not so knobby red lines with a fattie out back) and a chrome half fender in the back, i think that would look really sick.

If you don't mind my asking, what kind of engine did you find for a 20" bike?

It's a chris hill ch 80 happy time kit. You can get them in thunder bay ontario canada,it's a very reliable motor to use on most bike frame's.

Re: my 20 inch 1967 simpson sears bike build
your center pull brakes with the cable going through stem could possibly be a hazard if you dont pay attention! check always before you ride in case cable should break the brake arms release and the cable will go over the front tire causin a major endo

Re: my 20 inch 1967 simpson sears bike build
Actully there filestyle1 the front breaks that you refer to as center pull are called cantilever breaks and they came off of a mtb.they are pretty good breaks overall and I always check on them after evey ride and so far so good ,but i do thank you for pointing that out though.

Re: my 20 inch 1967 simpson sears bike build
D-uh! I can't believe I didn't see the brand in the first post! Oops! Anyhoo, It's a nice motor but a bit pricier than most I have seen. I have a 20" bike, but I abandoned the project because I thought that one needed at least 26". I have another bike that will be track inspired, but if I can mod out the 20", I'd love to do that instead. Does anyone know of any other manufacturers that make similarly sized motors?
