It would be of interest to put a profile of the bike shown here up against a profile of the Liverpool University bike (not the trike).

The nose of this bike seems quite blunt i.e. not a concorde type nose. I wondered how this compares with the other battle mountain bikes e.g. Delft, Liverpool, Canadian.

I also wondered about the wheel spacing compared to the other bikes.

What was the wind speed being simulated when the resistance of 11 Newtons was being measured?

The wind tunnel was running at max speed which was 78kmh or 48mph (IIRC)
