No, I'm not confusing anything Dan, and I've said nothing about illegal bikes not having to be registered so I don't know why you've raised that. I'm fully aware of all the posssible implications of illegality.
The exemption for electric assist bikes in British law (Not UK law) is called the EAPC regulations (Electric Assist Pedal Cycles) and it is law which is due to be cancelled shortly as it should have been in 2003. (Sorry for the typo above where I put 2002)
The reason for that cancellation is the fact that the EU passed a law on electric assist pedal cycles which is mandatory in all EU states and that requires all member states to cancel their own legislation. In the case of Britain it most definitely would have amended our road traffic act if the civil service had done their job properly in 2003, but it will do so within a couple of years when they make up for their mistake, which in essence was disobedience of a lawful EU order. This is nothing whatsoever to do with the EU's safety standard EN 15194 which also applies to us and will therefore be fully effective here once we've corrected our mistake, as I commented above and which led you to believe I was confusing the two issues. Please note that as the EU regulation applies to the whole UK, while the EAPC exemption only applies to Britain, Northern Ireland has been in a state of limbo until the mess is cleared up.
Here's the relevant EU legislation which overrides our road traffic acts, and I've highlighted the most crucial part in bold. You may also be interested in the last sentence in brackets, showing that the EU legislation might already be overriding our road traffic act in fact.
The EU-Directive 2002/24/EC concerning the Type approval for two and three wheeled vehicles has been released by the European Parliament and the Council on March 18, 2002.
In Article1 (h) “cycles with pedal assistance which are equipped with an auxiliary electric motor having a maximum continuous rated power of 0.25 kW, of which the output is progressively reduced and finally cut off as the vehicle reaches a speed of 25 km/h, or sooner, if the cyclist stops pedaling” are excluded from type approval.
Pedelecs which exceed the technical specifications must have a type approval and are classified as “mopeds”, and must consequently abide by all additional laws, i.e. motorcycle helmet, adequate brakes, mirrors etc.
The EU Directive 2002/24/EC comes into effect on
May 9, 2003 and will replace the current Directive
92/61/EEC.
Until May 9, 2003 the current national regulations concerning the status of pedelecs will remain unchanged.
After May 9, 2003, the EU Member States have the choice of either keeping their current regulations for another 6 months or changing over to the EU-directive.
By November 9, 2003 all Members of the EU are required to integrate this Directive into their national legislation and abolish their previous regulations. (My added note: it was passed into UK law on November 10th 2003, one day late, due to another civil service error)
Example:
In Great Britain pedelecs with a top speed of 15 mph (22.5 km/h) and 200 Watt motor are classified as bicycles. Pedelecs with a higher top speed or a stronger motor require a type approval.
No later than November 9, 2003, Great Britain must conform to the EU-directive: Pedelecs may have a 250 watt motor and be able to reach a top speed of 16 mph, and still be classified as a bicycle.

EU Directives and Regulations are applicable in all Member States. Where Regulations are directly applicable, Directives have to be implemented into national law. (However some provisions of Directives might have a “direct effect”, i.e. they are applicable even if the national legislator fails to implement the Directive in time.)
