It looks like it might be code 9, which is 340 rpm at 36v. That would make it a bit fast for 48v. The only way to be sure is to see how fast it goes on the speed display.Hope this helps

Motors don't have torque. Instead, they give torque that depends on the current and voltage. Maximum current depends on the controller, and it varies in accordance with speed. When manufacturers mention torque, it's meaningless unless they say the conditions under which they measured it, which are speed, current and voltage.Also, if it is G010 or G020 makes quite a difference. The G010 has a lot less torque.
You need to know the maximum current the battery can deliver. If you fit a bigger controller that takes a higher current than the battery can deliver you will ruin the battery.My batteries are 36v 21ah and 48v 21ah if that helps
That changes things. 340 rpm is OK for 48v. I think 17A would be a happy maximum. I can't think of any circumstances where you'd want more power than that with 20" wheels.20 inch
Yes, it's all a bit hand waving. Just whatever measure the company uses, the result is lower for the G010 than the G020 and the difference is noticeable in the real world.Motors don't have torque.

In any DC motor at any fixed voltage, torque is more or less proportional to current, provided that the current is in a suitable range for the motor.
