I think the @ username sends the user an alert.
It does normally, or at least has in the past - but the one in this thread didn't work for some reason.
Anyway, I'm piling in now. I've tried to skim the the thread, as I'm going to disagree with Drago, but see Benborp raised the relevant point.
Cycles cannot be done for 'speeding'. This is because the legislation for speeding offence refer to motor vehicles, and cycles are not a motor vehicle.
Some e-bikes MAY be argued to be a motor vehicle. Any vehicle with an engine is a mechanically propelled vehicle (mvp). For an mpv to become a motor vehicle it needs to be intended of adapted for the road, which most e-bikes probably are.
Normal cycles though, nope.
This does not however mean you can speed regardless - there are still separate offences of careless or inconsiderate cycling which could be considered instead - however these have to be proven abstractly on the standard of your riding, rather than a speed limit offence where you either are or aren't over the limit.
Cycles can and do break speed limits, and can also do so without breaking other motoring offences. There is a 20 limit on my commute that I regularly exceed - mind you, so do the cars and buses that still pass me! I have also broken 30 limits, and on a good downhill I suspect I could break a fifty - but I haven't ever achieved those sorts of speeds (yet!).
