WILIER E-BIKE X35 MOTOR LOCK NUT KIT

The Wilier E-Bike Mahle Ebikemotion X35 Motor Lock Nut Kit is a critical factory hardware set engineered to fasten the high-torque rear hub motor securely into the frame dropouts. Because electric hub motors place massive rotational twisting force (torque) directly onto the rear frame dropouts, maintaining pristine axle hardware is essential to prevent the wheel from slipping or damaging the integrated motor wiring harness.
