old bike-new power

I started taking apart the bike to re-purpose the parts for the generator.  I bought this bike for an old girl friend, I feel a little bad saying that it felt good to cut it in half. It’s been sitting in my garage for 3 years and it’s nice that it’s being put to use.

The design of this contraption has been a little fuzzy, but i think we are on the right track now.  Instead of the generator being built onto a chair it will be a separate device that folds up for storage and when being used can attach to any chair.  I drew a diagram because that always helps me understand things, but i’m afraid my scattered sketches may only aid in the confusion. The only thing i’m using from the old bike is the back half of the frame with the gears and rear wheel.  While playing with how this part of the bike would work in space it quickly became obvious that flipping the frame upside down and sitting more in a recumbent position would not only be more comfortable but give us more power.  The back half of the frame will be welded upside down to steel supports which also hold the generator and power converter that charge the battery pack.  Horizontal supports will slide into square steel tubing at the front and back of the base. These are needed because there will be a lot of side to side motion through peddling. To keep the generator from being pushed away there will be another bar that slides from the front and latches onto the chair of choice.  Got it?

To store the generator the chair latch slides back in, the horizontal supports are removed and the battery pack can be disconnected.  I feel really good about this new design and i feel confident that it will work well.
