Rear Fender for Boyueda S3-11– Replacement

This is a replacement rear fender designed for Boyueda electric scooters.

The original fender on this scooter model is too short and does not provide sufficient protection against water and dirt, especially when riding on wet surfaces where it can splash onto the rider’s back.

This model is an extended and reinforced replacement designed to improve protection and increase riding comfort in challenging conditions.

This design has been tested in real-world conditions for over 1000 km of riding, confirming its durability and functionality.

The two main parts of the fender were assembled using a two-component adhesive designed for plastics, ensuring a strong and reliable bond.

Additionally, the fender includes a built-in rear shock absorber protection cover, improving protection of the rear suspension area from dirt and debris.
