1) Installation Tool 

   ① Special wrench：
           
                 

   ② General tools：  6mm  Allen wrench       
                                            8mm  Allen wrench
                             

2) Cranket Mounting
   -  Tools： Special wrench

   -  Operation： Align the internal splines of the cranket 8 with the external 
      splines of the motor 7, press firmly to the end. Then tighten the lock nut  9, 
      counterclockwise with a special wrench with a tightening torque of 15Nm

    ③  Non-standard nuts installation
    -Tools： Special wrench
    -Components（see: factory configuration）：non-standard nut 4
    -Requirement： before tightening the nut, turn the motor clockwise until the 
        motor is close to the lower tube of the frame and does not turn until it 
        stops, then use a special wrench to tighten the nut, torque is 45-50Nm when 
        tightening

4. Speed Sensor Mounting: (MODEL:SVS1 and SVS2)

① Required Tools:

 - Slotted screwdriver (5-8mm)
 - Phillips screwdriver (3-5mm)
 - 4mm Allen wrench
 - Scissors

② 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.

③ Sensor Calibration


Model: SVS1


 - Sensor Adjustment: Locate the screws on the sensor using a Phillips
   screwdriver. Loosen these screws slightly.

 - Distance Optimization: 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).

 - Secure the Sensor: Once the optimal distance is achieved, tighten
   the screws securely using the Phillips screwdriver.


Model: SVS2


 - Distance Information: This sensor model does not allow for
   distance adjustment between the sensor and the magnet.
   
 - Maximum Distance: Proper functionality can still be achieved as
   long as the distance between them remains within 15mm.

5) Wiring

① Basic Required Components:

 -  Display（Specialized or optional）
 -  Battery（user-provided）
 -  Speed sensor（Specialized）
 -  EB-Bus cable（Specialized or optional)

② Motor Connections：

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.

③ Cable Routing Recommendation：
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.
