Order 1 set of electric bike kit from manufacturer-leaf motor and convert your bike to e-bike is a fun. But sometimes when we receive packages and don't know how to hanle it. Follow us:
Before install electric bike kit, we should test it first.
Step 1: Deliver your package
Spent some days on Internet, at last found leaf motor 's electric bike kit is the best. Ordered it and paid by paypal. Waiting for... About 3 days later, post officer knocked my door (EMS) and sign in it.
Check packing box first ,if it's okay. Pls disconnect electric bike kit box.
Step 2: Check all goods in package
Take out 26" hub motor rear wheel, bldc motor controller, lcd, throttle, brake lever, three button switches, speed signal wire and some connectors from packing box. Check each goods and make sure everything doesn't have fault.
Step 3: hold on 26" hub motor wheel
Put the hub motor wheel on your frame fork and tight both screw nuts.
Step 4: install magnet detector
Step 5: connect wires
1.Plug male 6-pin hall wires from hub motor cable to female connector from bldc motor controller;
2.Connect heavy yellow, green, blue from hub motor cable to heavy yellow, green, blue from bldc motor controller, color to color;
3.Two grey wires: connect these two wires/half speed; disconnect them/full speed;
4.Throttle connector is 3-pin that is easy to identify. Red: +4.5V, black: GND, green: Signal
5.Brake lever connector is white 2-pin.When hub motor is working, press brake lever is to cut off power;
6.Signal wire is black three pin plug that should be connected to white three pin female connector.
7.The other three pin connector from bldc motor controller is used for PAS;
8.Connect four pin lcd plug.
Make sure each wire is connected correctly. Power on battery.(Heavy red wire: +, black wire: - )Be careful,36V controller must work at 36V battery, if supply 48V DC, it will break the bldc motor controller at once.
Power on battery and press ON/OFF button on LCD one time, the LCD will light. Twist your throttle,hub motor starts to run. No strange noise...Press brake lever, electric bike kit system stops, loose it,the hub motor runs.
Pls watch video .

By test electric bike kit system, we found hub motor wheel, bldc motor controller, throttle.. everything is good. Next step is that we start to convert them on bike.

Hub motor kit ceased to function
On February 8th we ordered your 26” 48V 1000W front electric bike kit (1 set of 26” 48 1000W hub motor wheel with lcd bldc motor controller,twist throttle,brake levers,48V li battery) which was delivered to us on February 13th.Shipment is very fast.But the packing box is broken,we disconnect it and found the left brake lever was defective and I e-mailed you about getting a replacement set of levers. You told me that the parts would be sent. They never were received. I disconnected the lever plugs and have been using the bike for the past 1 month without them being hooked up.
Last week the bike ceased to function. I have 50+ volts going to the bldc motor controller connection but when I plug in the hub motor controller, the voltage drops to 1.8V and nothing happens. When I disconnect the hub motor connection, the voltage remains at 1.8V. As soon as I disconnect the battery, the electric bike battery shows full voltage of 50+ volts. The voltage indicator lights do not light up at all. So I have good voltage going to the controller but nothing works. I disassembled the controller to see if there was a broken connection or burned out part but can find nothing visibly wrong – when I connect a tester to the board the voltage shows 1.8 when should be 50 at the input connection. Something is wrong internally and I now need the hub motor controller to be replaced. I am relying on the electric bike kit to get to and from work so time is very important to me.
Please send me a new hub motor controller as soon aspossible. Also send me the previously promised brake lever set replacement at the same time (as long as it does not slow down the shipment of the hub motor controller). I would also appreciate it.

Problem with electric bike hub motor kit
Good day.I have bought from you 1 set of 48V 1000W rear electric bike kit that includes 48V 12Ah li battery,48v lcd brushless motor controller,twist throttle,brake levers with 26” 1000w hub motor rear wheel.Received all things.The order number lf283218U578679K. Shipment was fast and packing box was not broken.
But since I had installed hub motor wheel,motor controller,throttle..everything, I had following problems: Twist throttle was sometimes hard to begin electric bike motor uphill, with even slightest elevation.Electric bike kit either stops unintentionally, while I begin to accelerate hub motor, or doesn’t start at all. Usually it takes several amperes to start throttling.Electric bike motor never gets hot, only a little bit warm.
Electric bike kit (regenerative) brakes almost didn’t work at all. It is possible to stop with them only from the lowest speed of 5km/h approximately. If the speed is more than this, brakes just let the hub motor to freewheel. I don’t know if they are converting electrical energy.
When I tried to use USB cable to see, if it is because of lcd hub motor controller settings, I couldn’t connect to it. Software starts, when I choose “Connect” nothing happens with the program itself, only the electric bike motor starts to beep constantly. “Get settings” didn’t load any, changing parameters and saving them seems to have no effect on the electric bike motor behaviour. Only “Disconnect” button worked, but somehow it says that “Get settings” is complete, and any changes in parameters reset to their initial state. After approximately 360km, “Cruise control” button stopped to work. I opened hub motor and checked electrical connection to the motor controller itself, the button itself and wires are functioning properly. But I have absolutely no voltage reading on the button’s wires.
Read article from blog and forum,I doubt the problem comes from electric bike battery.It as said,there is a BMS inside li battery.Some cells would be dead because of overcharge or overdischarge.If dead,can’t charge li battery.Even if charge it,green led on charger will light at once.It looks like full charge,actually no any electrical energy inside battery.So when I ride my hub motor electric bike,the electric bike motor will stop in short time.
Please, help me to resolve those electric bike kit problems, especially, with “Cruise control” button.
