OH......i start to think i am really short of exercise.....
MY arms, legs are pretty Sour!
Tyres pressure are 95 psi. ...and I am 75 KG including everything.
Still wont go fast....it is ok on flat and smooth surface.
Here, in the uk, there is not much absolutely "perfect road"
I swear at some moments I do think does the Chinese 8-inches" Abike" performs faster?
