Routinely? On a standard commuter grade bike?

The Oxford Cycling Club, pictured here http://www.oxfordcyclingclub.co.uk/the-kings-men/ claim an average of 20 km/h (13mph) and they're lycra clad racing-bike riders.

I think you can break 25km/h readily, but I don't think that means we should increase the speed allowed with power assist.

There are moves to make city traffic 32km/h (20mph) limited which would put paid to your 40km/h anyway.
