It's not on the Brompton yet, Chris, though in-depth calculations and computer simulations indicate that my fuel consumption will increase by about 0.31 sospk (slices of sourdough per km) in still air on level tarmacadam meeting EN 432 at 20 kph.
I'll also be fitting a laser monitoring and head-up display unit which will automatically upload to the website. Once everything is finally calibrated, installed and commissioned we'll have more reliable information available which will aid future developments.
I hope this helps.

Though you haven't mentioned it, I am sure you've allowed for temperature and humidity changes?![]()
I have indeed, Chris.
And pressure in my tyres (which do, of course, meet EN 1097).
And bike clips on my dungarees.
Having said that, I'm not sure if I should I be wearing a tear-drop racing helmet as per the GB racing team.
At the moment I'm wearing a bobble hat.

Cutting the bobble off may improve airflow, or get a hair style like mine![]()
