Bosch Gen 5 Loose Motor Mounting Bolts

Confirm this cause by identifying if the ticking sound originates from the motor interface with the frame under high torque loads, such as during climbing. Verify bolt security by checking the torque on all motor mounting points. A loose motor will often exhibit microscopic movement against the frame, which can be confirmed by visually inspecting the mounting interface for signs of friction or metallic dust, indicating the motor is not held at the manufacturer-specified torque.
