[A1Foxxy]

Hi All,
I have a bit of a problem, I have 2 spare 700c eBike rear hubs. The problem I have is one is 1500w and I think the other is 2000w how can I tell the difference please.
Many Thanks for taking your time to read my post.

The larger motor should have more copper coil mass so weigh them?

There probably isn't any difference. If you bought them in kits, the difference is the max current in the controller, otherwise, Amazon, Aliexpress and Ebay sellers' descriptions aren't reliable.

Don't forget that motor's don't make power by themselves. They simply convert the electrical energy that the controller sends to them, so a 250w motor and a 2000w motor will give out the same power from the same controller.

Thank You for your reply. I will do that when I get back home. Cheers
