Same motor, same controller, different battery.
Oh dear the motor with the 48v battery goes faster ... Something must be wrong with the years and years of hands on experience of the people at ebikes.ca not to mention all those crazy hot-rodders over at endless-sphere.com.
Because we both know I am halucinating and don't know SFA about electric motors and pedelec controllers don't we? Hey did you know I haven't managed to fry a controller or a motor yet? Only 7,000 km under my belt so I probably still have time.
I think you need to read up on how a common KT controller actually works.
This is only valid for identical motors that were most likely built to "cover" more than one voltage.View attachment 28180

Or possibly both were 48 volt motors, one disguised.
The easy way to check that out, is to simply put each motor on a accurate weighing machine, a true lower voltage motor of otherwise identical manufacture, the lower voltage motor will be significantly lighter! e.g. Different parts! Especially the heavy copper field coils.
This was not detailed on the sheet you posted.
But manufacturers will do anything to reduce having to make extra and different parts, and relabeling a motor to a lower spec is the cheapest trick of all!
And also a very safe one for all concerned.
Which seemingly takes some people in as well!!
Furthermore, I see no information as to the internal temperature of the motors while under test!
A parameter that a good and valid test would have shown!!
Maybe intentionally not shown comes to mind as well.....
Therefore the test data you supplied, is not simply a "license" for anyone to believe its the same for all 36 volt bike motors available, as you appear to think!
Maybe "someone" wanted to mislead people for some reason, it's usually money!
Now if you produced the same data for all 36 volt bike motors in current usage, we could make a better/safer decision either way.
But as you have not managed to do that (neither could I!), then you should curb your statements for "informing" other people here with blanket, untested, information! Its simply not safe.
Its the only decent and correct way to treat our other members here.....
No unknown guesses that might mislead some!
I notice that still no one has offered to guarantee that! I wonder why!!!
If you are SO CERTAIN that its good info, why are you not stepping up?
Also, you apparently did not take the time to read up any of the links that I posted!
Your choice, as you have simply not had time to study either fully since I posted!
Also, I am sure the infos would have prompted many valid questions!
And as I have now informed the rest of our members here, with our conversation of what is safe to do and what is not, while trying to improve your knowledge...
I now see no more problems!
Now all here can make an educated decision if needed, with fully correct and safe information available!!
Also, if anyone wants to follow your route, at least he is fully forewarned!!
Do remember, that if I see you, promulgating unsafe, possibly dangerous information again, we will have the same/similar conversation again, OK?
I am retired and have plenty of time and interest in such things!!
regards and have a great day
