JOYOR S5-Z 18mm Large Wrench

The JOYOR S5-Z 18mm Large Wrench is a precision-forged hand tool designed specifically for servicing the JOYOR S5Z electric scooter. It is used to tighten or loosen 18mm fasteners commonly found on the scooter’s stem, axle nuts, and rear fender mounts. This wrench provides secure grip and optimal leverage during routine maintenance or component replacement.

Use this wrench when adjusting or replacing parts that require an 18mm socket or open-end fit—especially during wheel removal, brake caliper service, or handlebar assembly. Its robust construction ensures durability under repeated torque application without rounding fastener heads.

This is a genuine JOYOR service tool engineered for direct compatibility with the S5Z model—no adapters or modifications needed.
