While my starting technique is still unique, probably, I found myself doing something different on my ride today. In the past I have only been able to start with my butt entirely on the saddle and my tippy-toes on the ground with my calf on the edge of cramping....but my seat post must come higher which means I can't start that way anymore.

So today I experimented with something else. A portion of my butt is still on the saddle - the bike is still leaning over pretty far and most of my foot is still on the ground - and I started just fine

The first time I did this it was very quick and easy - the times I practiced after that was slower, due to over-thinking, but it was great progress. Now I just need to keep practicing until it becomes second nature. Stopping properly is fine, but starting has to become instinctive and it isn't quite there yet. That has to change before I can consider urban riding.
