Howdy, I finally decided to register after going over this forum for about 1 month and a half. I got this fantastic deal off of craigslist. This bike was sort of put together buy an 84 year old gentleman. He never rode it. Everything was brand new and never even ridden. When I got it I had to take the whole thing a part. The chain tensioner was to loose, and the sprocket/nuts were not tightened down. But hey, the fella was 84 years old. He was a great guy too. At any rate after dealing with the "stupid" chain tensioner pulley (I hate that thing), I finally took the motor mount plate off, and drilled and filed slots in the thing and remounted it, and got just enough length extension to throw out the "stupid" chain tensioner which I hate (did I already say that?). Now I have 3/4" slack on the chain, the wheels on straight and everything tightened down. Man I love this 7 speed bicycle. I use it for exercise and when I get too tired I use the engine. Bicycle: Schwinn Gateway 7 speed Engine Kit: 49cc Flying Horse 5G pull start.
