What's your top speed?

Really? Hmmm...interesting. [strokes chin]

See above.

+1 When I was bothering to log my rides I was consistently faster door-to-door fixed, but with much lower top speeds. I still notice it with nodders now - their speed fluctuates ridiculously, whereas I cruise (serenely) along at the same cadence most of the journey. It's like zen and shit.

You can be arrested by the police if you are traveling faster than the speed limit

However, the DVLA do not press charges against non motorized vehicle.

Is it me but when you travel over 30 - 35 miles an hour... your bike feels like it is skimming across the top of the road??
