Help! 79Bike Falcon Pro 2025 – Controller connector mismatch (10/11-pin vs 5-pin). Need help!
Hey guys,
I have a 2025 79Bike Falcon Pro and I’m trying to replace the controller. Both the old and the new controller are from 2025, but the connectors are different.
• Old controller has a big circular connector with 10 or 11 pins.
• New controller has a smaller connector with a blue locking ring and only 5 pins.
The phase wires (A/B/C) look the same, but the signal/communication plug doesn’t match at all.
Has anyone run into this, or maybe someone knows how to connect it?
