Hacbop E-Bike BZ-4 (8) PAS KT 8 Magnets Pedal Torque Sensor Ebike Parts Waterproof Connector for Electric Bicycle

It’s a lot more responsive than the old one that I replaced because that one wasn’t waterproof, and the magnet sits closer to the sensor,and grips the BB axle a lot better and doesn’t slip like my old one did.It works loads better when pedalling from standstill.

I only brought this for the disc which fitted perfectly and works ok
