I broke the frame! I learn best when I screw up. It was at the minimum insertion point mark on the post, but that was above the down tube. It suddenly got all spongy, starting to wobble, then cracked. Marin Bicycles has a huge warehouse in my town, Petaluma. It is filled with frames of all sizes and models back to 1986. They offer a full lifetime warranty on all their frames. I simply took off the motor system and reinstalled the original parts. The dealer photographed it and I got a new frame the next week. Then it was a matter of moving the components, adding a longer, thicker post, and reinstalling the through frame conversion. I rode it for another year then put it back to the original parts and sold it to a barista, Marco, who loves it. The motor system went to another bike. Here is a step-thru version. Yes, the seatpost is way too high at the minimum insertion mark. I have long legs.
The owner was sold a $16500 bike that could not take her hill. She was promised it would. She had to walk it 2 miles uphill. I got her a full refund and she purchased this bike for $650 at the time, across the street. I converted it and it climbs anything, just fine. The bar is more backswept than the original. See any ugly wires or connectors? Not using any zip ties on a conversion is like skinny dipping. To see the thread, search for Custom in the title, and by user PedalUma, to see a full build process.
