Right crank 10 – Requirement: central axle screw locking torque is 35-40Nm -Diagram? Speed Sensor Mounting: (MODEL:SVS1 and SVS2)? Required Tools: – Slotted screwdriver (5-8mm) – Phillips screwdriver (3-5mm) – 4mm Allen wrench – Scissors? Sensor Mounting: – Secure the sensor to the bicycle fork using two cable ties. Ensure the sensor is positioned comfortably within the designated area. Magnet Installation: – Using a slotted screwdriver, attach the magnets to the spokes of your wheel. Alignment is crucial: During installation, ensure the flat surface of the magnet where the magnetic field is strongest aligns directly with the circular mark on the sensor. Sensor Calibration Model: SVS1. Locate the screws on the sensor using a Phillips screwdriver. Loosen these screws slightly. While holding the sensor in place, carefully move it to achieve a distance of 2-5mm between the circular mark on the sensor and the flat surface of the magnet (often where the magnetic field is strongest). Once the optimal distance is achieved, tighten the screws securely using the Phillips screwdriver. This sensor model does not allow for distance adjustment between the sensor and the magnet. Proper functionality can still be achieved as long as the distance between them remains within 15mm. 1-Sensor 2-Tie 3-Magnet 4-Screw 5-Receiver. 1- Speed sensor 2-Cable tie 3-Magnet 4-ScrewM5X8 5-Receiver 6-Plastic cap. Basic Required Components: – Display? Carefully plug the EB-Bus cable, battery, and speed sensor connectors to their corresponding connectors on the motor. The other ends of the EB-Bus cable connectors can be plugged into the display, brake lever or brake sensor, throttle, etc. To ensure optimal performance and longevity of the cables, we kindly recommend avoiding routing all cables through the narrow space between the motor and the frame. This will help prevent the cables from being pinched or damaged. Due to different communication protocols, our motors can only be used with the accompanying accessories we provide and are not compatible with accessories from other brands. Using unauthorized accessories can cause damage to our motors and displays, and we will be unable to provide any after-sales support.
