Bosch Explains All the forthcoming new regulations

Yes. A global standard of 750w max output would kill demand for DJI's offering stone dead. This is nothing more than an attempt to shore up EU manufacturing. I'm pro EU and can see this as clear as day.
Although I agree, that isn't the whole story. The USA with their new three classes law for pedelecs has fallen into line with the rest of the world's adoption of EU law, but with the difference of stating 750 watts rather than the EU similar permission disguised as "Continuous Rated Maximum Power".
With the USA an important market Bosch naturally want to fall into line with that for marketing convenience.

I doubt any change is likely to happen soon in the UK - they've only just recently rejected 500W after a consultation, wake me up if it ever does here.
Ve vill turn zis DJI threat to opportunity and dominate the vorld haha! Sieg Bosch! How do vu laak dem schnitzels Chinese communist peasants?

I think that Bosch guy made a lot of sense with what he said. 750w maximum power output would be easy to measure. It's roughly 22A at 48v, which should be enough to get a 100kg rider up the steepest hills they're likely to encounter without getting a heart attack. I don't know where that leaves the cargo bikes and those pedal assisted Amazon delivery vans. They would fall outside the EAPC classification, which doesn't sound too unreasonable to me.
nother problem I thought of is that the 750w max output power wouldn't be easy for the police or anybody else to check. They'd need a dynamometer. When I said it would be easy to meaure in ny previous post, I meant in a lab if there were any dispute about it, not at the roadside. You can imagine that when motors have 750w on them, some people are going to run them at 25A or more, though there wouldn't be a lot to gain from that if they're limited to 15.5 mph.
The more I think about it, the more I'm tending to think that the Bosch guy is wrong. The amount of power you have over 750w doesn't matter if it cuts off at 15.5mph. The extra power would just be an embarassment. What can you do with it? They might as well abolish the power limit and just concentrate on enforcing the speed. It's the speed that makes a difference between a bicycle and a motorbike, not the power, and you have to pedal an EAPC to get any power. If you're limited on speed to 15.5mp, it makes an incentive to keep the power low anyway, since power above 750w would only give disadvantages in most cases.

Agreed, for most of us. 750W and 100kg all up climbs 8.5% at 15.5mph.
Pedestrians would get caught out if the acceleration were unexpectedly high. I don't know if the police are allowed to test in motion but a time to reach, say, 15kph would be more pertinent than a power limit, and we know what would happen with no limit at all.
I hope the EC body doesn't fall for Bosch's 'blended' presentation mixing law with their offering. If they were to put a limit on % assistance in a protectionist effort to undermine hub-motor bikes it would boot the elderly, the less able or obese and riders with trailers (non-commercial) into a separate class - not good at all.

Motors don't have a power, so there's no way a COC can certify it. The power depends on the controller and battery.
I should have been clearer. I wasn't talking about the motor. I was talking about the whole manufactured bike. Any bike without a cert won't conform.
