The EU Court of Justice yesterday ruled that e-bikes are actually bikes, not motorbikes, which means e-cyclists aren’t obligated to be insured in the same way as motorists.
I'm sure that if you see the fine print, this means that pedal-assist ebikes that have 250W motor and are limited to 25kph (15mph) are considered bicycles. Something like a Surron is still considered a motorbike and needs to be registerated, insured, needs a licence and is only allowed to be driven on the roads among cars - as they should.
Sounds exactly how it was regulated in Germany, except for the license I think. It's pretty much handled the same as a moped, which I think is totally fair.
I sure would like to read the actual ruling, but from what I see in the article, this applies to pedal assist e-bikes, and wouldn't apply to e-bikes that have a throttle which is operated by a way other than pedaling (like a thumb or twist throttle). I have to think there's a maximum speed and/or weight as well, otherwise someone could very easily build a large, heavy, highway-ready "e-bike" that just uses pedaling for the throttle, but is in every other way an electric motorcycle.
Of course EU regulations, contrary to the US, limit pedal-assist bikes to a maximum continuous rated power of no more than 250 W and a speed to 25 km/h before cutting out power, leaving you to rely your legs for more speed.
