Interesting. So they're using a chassis dyno to measure 200w at the treads. I suspect you'd need a fair bit over 200w to even turn the rollers. Obviously this figure will be a far cry from what is displayed on a watt meter or CA as power coming out of the battery but I'd be very interested to know what sort of CA power figures result in around 200w on the rollers once motor inefficiency and drivetrain losses etc are taken into account. I'd also like to know what sort of motor/battery/controller combo that the bike that failed was running and what number he turned out._Chris_ said:OK just now I called up The guy that is doing the testing of illegal bikes...
He sais he has only had to test 2 ebikes and the 200w one wouldn't even make the roller on the motorbike tester work.
There you go Chris, you have your homework for today. Report back to me in the morning
t3sla mentions 500-800w being seen on his pedalec so if this has passed euro testing schemes as 250w that means for 200w motors we could probably get away with seeing battery wattage readings of 400-650w...
