The EU legislation is a mess and is not used in most of the world where their legislation is far superior... We desperately need to get away from this dire EU legislation and return to standards similar to being used elsewhere in the world.
By most of the world you presumably mean USA - a country that has totally lost the plot when it comes to everyday cycling, where the cycling conversation is dominated by cycle sport, resulting in lax e-bike regulations that let people pretend that a 750W machine doing 20mph is just like a pedal cycle. It isn't of course, with the result that e-bikes are getting banned from the few places where one can ride without traffic in that unhappy country.
I've seen so many conversations on forums about how hated the EU legislation is
Of course it's hated, by those who want to speed and have the fun of punchy accelleration like a motorbike, without the hassle of registration, insurance and a motorcycle helmet. Tough. If you manage to get US-style regulation here, you'll lose the goodwill of the pedal cycling community. You will no longer be welcome amongst us and we will campaign to have you excluded from the few places and priviledges afforded to cyclists in this country. You can ALL then go play with the motorcyclists.
Across the EU throttle based ebike kits still sell in huge numbers and the police in many countries simply ignore the legislation because its just garbage. Forcing a pedelec system on people is utterly moronic it discriminates against the weak, disabled and elderly. I would be embarrassed to admit any connection to this dire legislation.
On the contrary, in that video by an American visiting Europe that you posted a link to above, he says how Europe is a huge market for ebikes, where they're nearly all EU style e-bikes. Sure there must be some illegal bikes, but they are a tiny minority and Europe satisfies the e-mopedists with its speed pedelec class. Admittedly that hasn't caught on in UK but that's because UK has a downer on mopeds. I don't know the details because I'm not into motorcycles but it is evident that something happened to the UK legislation in the seventies that made mopeds all but disappear from our streets, whereas they remained popular in the rest of Europe. If you want speed pedelecs to be available and more easily usable here, I suggest you go talk to the motorcyclists, whose proper business it is to sort that out.
As for Bosch peak wattage you see it everywhere in forums in comments for those who can measure current draw. A thread here shows the Chinese mid-drive motors aren't peaking as high as Bosch perhaps 200W difference and consequently they don't quite match Bosch Nm output. Here there is a claim of 850W for a Bosch motor but I'd say its more common to see around 800W or just under 800W as stated maximum power. The current draw has been measured on a Bosch battery and for a reasonably prolonged period for something like 600W. This has been widely discussed on many ebike forums. Most of the information about ebike motor current consumption is forums because most commercial information is inline with what the the motor manufacturers want to present with regard their fake 250W rating.
I thought so, you are indeed confusing electrical power input with mechanical power output.
Measuring the power of e-bikes by how much electricity they consume, makes as much sense as measuring the performance of racing cyclists by how much food they eat!
There will be some kind of relationship, but it's rather tenuous because each case depends critically upon how efficiently a different source of energy is converted to mechanical work, rather than being wasted in heat. And when it comes to ensuring that an e-bike moves something like a pedal cycle, what matters is how power is delivered to the wheels.
