Does flecc mean by the undernoted that a pedal cycle converted to an EAPC requires single vehicle approval?
No, it's not required by law, and I certainly wouldn't bother. If plating was being enforced I'd plate my home build e-bike myself.
However, for me and for all who build a special, that is then open to challenge from the police and that could result in an expensive court case with a need for inspections and professional witnesses.
Anyone wishing to avoid that potential problem will need to get official approval of their home build and it's plating, and the only body responsible for this kind if testing is the SVA, despite there being no existing procedure for this. Obviously presenting an e-bike for testing would cause head scratching and possibly the constructor advised to go away in the hope of the problem disappearing or being left for someone else to deal with.
The best approach would be at the outset of a home build project to write to ones nearest SVA test centre advising ones intention to present an e-bike for inspection to verify it's exemption status. The letter could with advantage be copied to the DfT and marked thus, to keep them in the loop. That will hopefully trigger action to institute a procedure for e-bike verification. The e-bike could then be safely used on the basis that it conformed to the law and that official verification had been sought. Since that last step is not a requirement, there should be no problems and any police action is much less likely in such an instance of obvious good intentions.
Basically all three of the following states are legal, but each step in turn lessens the likelyhood of possible challenge further:
1) E-bike constructed and plated and then used.
2) E-bike constructed and plated, exemption test applied for from the SVA and the bike used meanwhile.
3) E-bike constructed and plated, exemption test applied for and bike not used until after the test and subsequent approval.
