TREEWK, Here's the best picture i can post right now of the drive. I find your project very interesting. I had thought of sticking a pocket bike motor on a bicycle not so long ago. But the lady at the DMV changed my mind rather quickly however. Your Mongoose isn't the bike i originally thought it was. I was thinking of the bike that looked similar to a dirt bike. I still have the original rear wheel, but it's rather bent out of shape. A monster pothole ate it for supper on the way home from work one day. Not that it bothered me that much, i'm not a big fan of 700c rims and tires. So anyway i was stuck with a freewheel that wasn't of much use, so i decided to put it to use. The motor does turn when i pedal. I had hoped to possibly get some regen out of it, but my best effort only got 11.34 volts, a far cry from the needed 24v. I still have to put this bike and myself on a diet, as we are both still a little too soggy.
