I keep reminding myself to view this whole project as an experiment. That sounds better when things do not work out as I had hoped - like the speedometer, for instance. At 11:30 last night I was taking apart the PedGen, trying to install the analog speedometer on the small sprocket. I had to bend the peg on the speedometer to make it fit the small radius of the sprocket (since it was intended to fit on the much larger radius wheel). Adding the extra layer of the speedometer caused the space between the two arms of the bike frame (on either side of the wheel) to become very tight. Once I put the bicycle back together with the speedometer in place, it was so tightly packed that the speedometer would not turn freely. Then the speedometer peg, that was hooked on the sprocket, actually began to bend. At that point I decided some sleep would be beneficial.
Now it is the next day and I don't have any brilliant ideas for making the analog speedometer functional. It seems like I would have to bend the bicycle frame in order to widen the gap between the two arms that attach to the wheel. I am not willing to do that just for the sake of avoiding a digital speedometer. I am also concerned that soon the analog speedometer will be ruined and I will not even have the option of returning it.
