It’s interesting you mention the weight distribution and stability. Maybe it comes down to individual preference. I am perched out over the front wheel quite a bit on my 51 P2, but it handles like a dream, whether going downhill, in the wind, going downhill in the wind, etc.
Yep. I’m way out over the front wheel on mine also. Don’t know why that would hurt stability. If anything, seems like more weight on the front would make it more stable and less effected by wind. Instead of a rearward weight bias that is more common, I have about the same weight on both wheels.
If it works for you, great. However, the front wheel is involved in steering and the back wheel isn’t, so I’m not sure that in general having equal weight on both wheels is a great idea for general handling. As for stability, I tend of think of the issue as longer wheel base vs. shorter wheel base, and everything else being equal (i.e. same bike model, same fit coordinates), having a slightly longer wheelbase is better for stability.
