I did some research on that topic, but it did not really become clear to me.
Situation: I live in Switzerland. Switzerland did not declare to treat Mopeds as Motor Cycles - Article 54 (2). My fast electric bike is registered here as Moped, it complies with the swiss regulations, the rules of article 44(2) and has a swiss number plate and documents. It has a power of 1000W. However, in many other countries fast electric bikes must not have more than 500W to be registered as mopeds.
1) Can I drive it in a country which did not declare to treat Mopeds as Motor Cycles (e.g. Austria)? In other words: is compliance to the rules of the vienna contract and the swiss decision, that my E-Bike with 1000W is a Moped allow its use in those countries?
2) Can I drive it in a country which declared to treat Mopeds as Motor Cycles (e.g. Germany), if it complies to the rules of the contract, especially the technical rules of appendix 5?
