Yes. The current EAPC regulations date from 1983, whereas the EU regulations weren't introduced until 1999, with the introduction of EU wide Type Approval, but with an exemption for pedelecs and ebikes, leaving each state to continue to apply its own laws until Type Approval harmonisation. The UK adopted EU pedelec regulations in 2003, but rather unusually has not (yet) rescinded the national regulation.Did Britain's regulations pre-date the EU's ? If they did, existing regulations were being changed as opposed to new ones being introduced with benchmarks already in place.
This leaves the UK in the rather odd position of having two sets of (different) ebike regulations, one that requires EU Type Approval and one that only requires national regulatory compliance demonstration.
