How to Adjust the Rear Fender Height on an Arwibon Q30 Scooter
This tutorial covers rear fender height adjustment on an arwibon q30 scooter. The rear fender bracket has more than one mounting position, so the fender can be moved higher or lower depending on the tire clearance you need.
The main point is to use the same mounting position on both sides.
Tools Needed
Prepare:
- Allen key
- Protective gloves
Step 1: Locate the Rear Fender Adjustment Holes
Move to one side of the rear fender bracket.
The official arwibon q30 video shows the adjustment area at about 00:00.
You should see two mounting positions on the bracket.
These holes allow the rear fender to sit at different heights.
Step 2: Remove the First-Side Mounting Screw
Use the correct Allen key to loosen the mounting screw.
The official q30 scooter video shows this at about 00:02.
Remove the screw completely.
Support the fender with your other hand so it does not drop or twist while the screw is out.
Step 3: Move the Fender Up or Down
Hold the rear fender and move it slightly upward or downward.
The official arwibon q30 electric scooter video shows this adjustment at about 00:04.
Choose the mounting position that gives the clearance you need.
The higher hole position increases the space between the tire and fender, while the lower position brings the fender closer to the tire.
Step 4: Align the Selected Mounting Hole
Move the fender until the bracket hole lines up with the selected adjustment hole.
The official video shows this at about 00:08.
Make sure the holes line up cleanly before reinstalling the screw.
Do not force the screw into a misaligned hole.
Step 5: Reinstall the Mounting Screw
Insert the original Allen screw through the selected hole.
The official arwibon q30 video shows this at about 00:09.
Start the screw by hand if possible.
Then use the Allen key to tighten it.
The video shows the screw being secured at about 00:15.
Step 6: Adjust the Opposite Side
Move to the other side of the arwibon q30 scooter.
Repeat the same process:
- Remove the mounting screw.
- Move the fender to the same height.
- Align the same corresponding hole.
- Reinstall and tighten the screw.
Both sides need to use the same adjustment position.
Do not leave one side in the upper hole and the other side in the lower hole.
Step 7: Check the Fender Alignment
Stand behind the scooter and look at the rear fender.
It should sit evenly over the rear tire.
Check that one side is not noticeably higher than the other.
If the fender looks twisted, recheck the mounting holes on both sides.
Step 8: Spin the Rear Wheel
Lift the rear wheel and rotate it by hand.
Check the clearance between the tire and rear fender.
Listen for any rubbing or scraping.
The tire should rotate without touching the fender.
Step 9: Check Clearance Through Suspension Movement
Press down on the rear of the scooter to move the rear suspension through part of its travel.
Watch the gap between the tire and fender.
Make sure the tire does not contact the fender as the suspension moves.
This check is especially useful after changing to a different tire size or tread pattern.
Final Check
Before riding the arwibon q30 electric scooter, confirm that:
- both sides use the same fender mounting position;
- both adjustment screws are secure;
- the rear fender sits straight over the tire;
- the tire does not rub the fender while spinning;
- there is still clearance when the rear suspension moves.
This procedure follows the official Arwibon Scooter video “Q30 Rear Fender Height Adjustment | Arwibon Q30” and covers the rear fender height adjustment shown for the arwibon q30 scooter.
