Vertical STA, ultra slack HTA, low saddle, second crankset very high, second crankset that seems near to knees while pedaling on lower crankset...
I would be curious to see a video of that bike ridden in each position.
НТА=64,85˚
Trail(Т)=96,56mm
Base(WB)=1492mm
Stability (controllability) coefficient К=(T/[WB+T])x100%, the best lies within 5%...7,5%
K=(96,56/[1492+96])x100%=6%
Just in between 5%...7,5%
STA=90˚watch post # 9
