I think u dont own a city.. Bro there isn't any NOB under the steering of this model.I know because i own one.
@Fawadshah
It's at fixed position.I'm 5'11" too but my knees or should i say thighs and steering have approax 3-4 inch gap.I think there is some problem with ur seat.
BTW would love to see the pics of ur ride and may b v could meet up someday somewhere to share knowledge..
