this is the number on the controller (crr209750 9nu20) which leads me to believe its a 750w controller on a 250w motor configured to run at 48v
serial on the motor itself is MMG340260 16 021F3Y4130390
its literally the exact same as the OP. i bought it from here. its the 48v 250w version.

has no one got an actual solution to this surely the throttle can be made to work via the programming cable. i have the same eu ordered motor and the throttle doesnt work
