OK lets remove 2 of the wheels.
I am riding in the street on a bicycle with an auxiliary drive in the front wheel which is fully EN15194 compliant. I add a motor to the rear wheel and it is powered by electricity generated by a generator in the pedal box, no chain just 100% electric motor drive on the rear wheel. Now I don't know about the German road code but in France this vehicle has a name and a classification, it is called an electric moped. It requires type approval, insurance, a number plate, a helmet and a basic drivers license (BSR). That is what any French police officer stopping me would point out as he added up the fines for the missing equipment...EPAC Pedelec with e-chain he knows nothing about because there is no legal framework in the road code for that, only for electric moped.
That is what Frikar would be if they ever tried to sell it in France, the extra 2 wheels don't make it anything else than a 4 wheeled electric moped just like the Twizy45 or the Citroën Ami/Opel thing. That it has pedals to generate the electricity and a pedelec mode does not change the fact that the primary drive remains an electric motor putting it fully in the light electric vehicle class. On pure logic alone any attempt to have it classified as an EPAC would fail, what is there to stop Renault and Citroën from installing pedals and electric generators? On passage through the French technical services no engineer would say this is an EPAC, how could they with an electric motor providing drive?
This whole e-chain dream is getting ridiculous, it is just a ploy by manufacturers to get their e-mopeds on the cycle path, nothing more, nothing less. I repeat again: a generator and pedals do not make a light electric vehicle into a cycle.
Dream on...
