   **Handlebar Shifter Inspection:**
   
     - Examine the shifter on the handlebars for any visible damage, bumps, or dings.
     - Ensure that the shifter is in good condition.
2. **Shift Sensor Check:**
   
     - Follow the cable from the shifter to the shift sensor (if included on your bike) and inspect it for damage.
     - Verify that the shift sensor is not smashed or damaged, as it plays a crucial role in stopping the motor during gear shifts.
3. **Cable Inspection:**
   
     - Examine the cable for any visible damage as it travels down to the frame.
     - Inspect the cable where it enters the frame, even though the internal components cannot be seen.
4. **Rear Derailleur and Cassette Inspection:**
   
     - Check the rear derailleur for damage, rocks, bends, or kinks that may affect its performance.
     - Gently move the cassette to inspect for any visible damage, cracks, or broken cogs.
5. **Chain Examination:**
   
     - Inspect the chain for any signs of damage, bends, or kinks.
     - Examine the front chainring, especially the teeth, for any bending, damage, or breakage.
6. **Tuning the Derailleur:**
   
     - Once all components are visually inspected, proceed to tune the derailleur to ensure proper functionality.
     - Refer to the [Derailleur Adjustment](https://kb.quietkat.com/en/support/derailleur-adjustment-guide?hsLang=en) or [Limit Screw Adjustment](https://kb.quietkat.com/en/support/adjusting-limit-screws?hsLang=en) instructions for direction on tuning your derailleur.
