A bike's resistance system does not respond to level adjustment commands from the console. Which is the most likely cause category?
- AA faulty reed switch on the flywheel
- BA failed resistance motor/servo, broken wiring harness, or console communication fault
- CA loose pedal spindle
- DRunning belt over-tension
Correct Answer
A failed resistance motor/servo, broken wiring harness, or console communication fault
Explanation
Resistance non-response on a powered resistance bike points to the resistance actuation chain: the console output signal, the wiring harness, or the resistance servo/stepper motor itself. Diagnose each systematically.
