Everyone,
There are two spare 700c electric bicycle rear hubs. The problem is, I think one is 1500W and the other is 2000W. How can I see it?
Thank you for reading the post while you are busy.
The larger motor should have more copper coil mass so weigh them?
It’s probably no different. When purchased with the kit, the maximum current of the controller is different. Otherwise, the Amazon, Aliexpress and Ebay sellers’ explanations are not reliable.
Remember that the motor itself does not generate power. The motor only converts the electrical energy sent from the controller. Therefore, 250W and 2000W motors exert the same output for the power supplied by the same controller.
Thank You for your reply. I will do that when I get back home. Cheers
