So I bought a new Focus Thron 2021 a few days ago. Has Bosch CX Gen 4 motor.
For first 70km or so I didn't notice this noise or sensation at all then all of a sudden it started happening. It happens at low cadence high torque (eg uphill). It makes a creaking noise and each time I hear the noise I feel a disturbance in the pedalling. Before it started happening it would just feel smooth going uphill now it feels bumpy through the pedals.
