            5-8mm Slotted screwdriver
            3-5mm Phillips screwdriver
            Scissors


2) Crankset Mounting
   -  Tools： Special wrench

 - Step 1- Align the chainring 8 with the motor 7 : Ensure the
   internal splines of the chainring mesh perfectly with the external
   splines of the motor.

 - Step 2- Press-fit the chainring: Firmly press the chainring onto the
   motor axle until it reaches its seated position.

 - Step 3- Tighten the lock nut 9 : Using a special wrench, tighten
   the lock nut in a counterclockwise direction to a torque of 15 Nm.

3) Motor Mounting

 - Position the motor: Place the motor on the right side of the bicycle
   frame, aligning it with the bottom bracket opening.

 - Insert the motor: Carefully guide the motor into the bottom bracket
   until it reaches its fully seated position.

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.
