7. Best heat sinking with Aluminium Case
8. Black anodized Aluminium Controller Case against scratch

Installation Guidance:
1) Unscrew the existing rear wheel screws, remove your rear wheel;
2) Install the motorized wheel and fasten screws;
3) Fix LCD, Brake lever and throttle;
4) Fix PAS at left side (If you don't need PAS, you can also don't install it).
5) Put Controller at suitable position and connect all wires.
6) Turn on battery, throttle key and LCD, set correct value from LCD
Correct wheel size setting: according to your wheel size
Correct max speed setting: set it at max value 75
Correct motor magnet pole quantity 46
Save all value and restart LCD display 

1.  How shall I match my motor for first time use? (Very Important)
(Please check Controller Connection Diagram and Manual, Page 1)
1). Lift your motor wheel off ground (very important)
2). Connect Self-learning plug 6-8 seconds
3). You will see motor wheel rotate slowly
4). Please check whether rotation direction is correct
(a). If correct direction, then keep 6-8 seconds, then disconnect
(b). If reverse direction, then disconnect and plug again till get correct rotation direction, then keep 6-8 seconds, then disconnect
5). Motor and Controller Pairing finished!

2. Can I use this controller without display?
Yes, you can use this controller without display, just need to connect jumper connector (Please check Controller Connection Diagram and Manual, Page 4, point No.3) 

3. How can I limit speed?
In some countries, below 25km/h speed is required on road, you can switch on/off speed limit function by connecting a simple switch to controller speed limit plug, or you can even connect jumper connector to always limit speed (Please check Controller Connection Diagram and Manual, Page 9-10, point No.12)
