Hey Everyone! Nice place you have here...

I'm not new to machinery, but I am a total no0b when it comes to the World of Motorized Bicycles. I bought a single two-stroke kit from an acquaintance at work; he said he and a friend had purchased ten of them...

Now you guys have prolly seen and heard the same stories from countless others, and I haven't browsed your site for other Schwinn builds, so, please bear with me.

It appears as if I'll have to modify just about everything to get this kit solidly and reliably mounted on this particular bicycle... the first thing is that the engine position will require custom mount spacers and longer mounting studs. The bike's seat and downtube dias. are smaller than the kit's existing mount bracket shapes too.

It was suggested that I check the kit's drive chain length before I nailed the final motor position... that's when I opened another can O' worms with the rear sprocket mounting issues.

I have access to a friend and his machine tools, so we bored the sprocket center to fit the Shimano single-speed coaster-brake hub only to find that the Shimano brake arm will not clear the sprocket's bolt circle.

Is there another brake arm with a different shape I can use tht will fit the axle's flats dimension?

The bolt circle is also slightly smaller that the hub's spoke flange o.d. We can either drill a new, larger bolt circle, or I can slightly groove the hub flange if I can use a different brake arm or even a differeent hub, but then I may need to make a ring spacer to replace the eighth-inch or so removed from the sprocket's centerbore. Then I've misplaced the nine-hole rubber donuts that sandwich between the sprocket and three-piece plate.

ETC.

This is what I'm up against so far. Hahaha...

Looking forward to hearing from someone; thanks for being here!

thats the first trike ive seen and dug!

very cool, love the paint and matching seat!

I also am using a schwinn Cruiser. I bought mine put together so I cant help there. I have had problems with the muffler staying tight. Already lost one I dont want to lose another. I can say this, my bike sat for about a year, got rained on and everything. I put new gas in it an within a block of pedaling it started right up an hummed right along. The problem with the muffler was the bottom frame was to wide so I had to bend it to fit the new pipe. The previous pipe was also bent. Hope you have an easier time with yours then I have had so far. Still it is a great ride.
