I normally ride about that speed but not on a shared pavement.Mussels you speed freek i would never risk doing that kind of speed on a shared pavement .
I went past a family on a shared pavement going by slowly and the father decided to shout a few obscenitys at me i was quite tempted to punch his lights out.nigel
I can maintain about 18mph up mild hills, 20mph on the flat and up to 40 downhill but I only break the speed limit in a couple of places. Even though I've dropped the gears I can still pedal to 30mph but not on the flat, it helps that I have put a balloon tyre on and it has raised the motor gearing by about 10%.
I mostly get positive remarks about the speed I'm going and only scare pedestrians who are very blase with their green cross code.
