We need pics of controller and lcd connectors.
The motor phase wires Grn, Blu & Yellow are a permanent fixture other wise motor doen't run.

Not much to go on with the link as pics are of poor quality, though looks like controller and LCD are incompatible connector wise.
Best try contacting supplier with pics and ask for a refund or go through Aliex and open a dispute.
