I don't know how long bikes like yours will be around under our law Synthman, for the simple reason they aren't 250 watt machines. They are being declared as that to make them appear legal here, but they will always be at risk of detection at some future time.
These are common on the Chinese e-bike market where they don't use the sort of normal-bike looking types, and they are usually around 700 watts rating. One of our members who visits China regularly has one of these over there for his use and it's 680 watts.
That's why the speed, they are indeed easily capable of 20 mph and also climb well with little pedal help, a combination that is completely impossible with a true 250 watt rating even on a much lighter e-bike, such as that Powacycle you passed.
So best you keep your fingers crossed that there's never a crackdown on standards, since that would wipe these off the UK roads.
