Welcome to the site.
You can check the current going to the motor by putting an amp clamp around the blue, yellow, green motor wires. https://www.newark.com/tenma/72-2985/dmm-clamp-auto-100a-3-5-digit/dp/95Y2983
newark is a division of farnell that has distributors world wide.
You want 6 A or higher with a load on the motor. Wheel up in the air won't draw any amps. 26 A max for a 1000 W motor typically.
You could also check the continuity through the motor wires with it unplugged. Use an ohms scale of a multimeter. Should be 10 ohms or less.

Are they the same model? If so, then you can (a) swap the battery and (b) swap the hub motors. Did the slow bike ever run right?
