bike conversion kit help

Posted by on January 1, 2022 Comments Off on bike conversion kit help

Q：I bought the 1000 W bike conversion kit 8 years ago in your company. Today the hub motor broke. Initially there was some creak in the motor at a high current. Then unexpectedly the motor had slowed down with strong vibration. Now the throttle does not work and the motor rotates hardly.
Could you help me?

A：Please check three pairs of motor and controller.(Heavy Yellow,green and blue)
When you ride,only one wire loose,it will be strong vibration.
Generally the controller is broken.
Remove motor wires from controller.Make three wires(yellow,blue and green)NOT touch together.Use you hand to rotate motor easy.If need more info,please visit https://www.leafbike.com/ site.

Q：I found the fault. It was due to a short circuit between two phase wires in the area of them connections. I made too weak isolation.
Thanks a lot, Peter!

E-bike Not work – electric controller issue or hub motor?

Posted by on December 31, 2021 Comments Off on E-bike Not work – electric controller issue or hub motor?

Riding an electric bike is a funny thing.Sometimes,while riding happily,it stop working and can’t re-start.
If you think your lithium battery is new,can’t cause this issue.Now you should check controller or bike motor,how to check?

If you have volt meter,you could measure as below? So that you can make sure the problem comes from controller or motor
If you can get the same data as below 1, that means controller’s everything is good
If you can’t get the same data as below 2,some hall senor has problem.

1. Connect all wires,power on.Just disconnect that white big plug with five wires( yellow,blue,green,red,black)
Then measure controller’s hall sensor:
* The voltage of red and black is about 5.0V
* The voltage of yellow and black is about 5.0V
* The voltage of blue and black is about 5.0V
* The voltage of green and black is about 5.0V

—————————————————————————–
2 Connect all wires,power on.Also,connect that white big plug with five wires( yellow,blue,green,red,black)
Then measure motor’s hall sensor:
* The voltage of red and black is about 4.5V
* The voltage of yellow and black is about 4.5V or 0V (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)
* The voltage of blue and black is about 4.5V or 0v (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)
* The voltage of green and black is about 0V or 4.5V (when use hand to turn motor,the voltage will change from 4.5V-0V-4.5V-0V)

My 26 inch rear electric hub motor kit works

Posted by on December 31, 2021 Comments Off on My 26 inch rear electric hub motor kit works

Q: Received my 26 inch rear electric bike kit. Finally managed to get it all working. The LCD display does not go over 20 mph ? Can you think why？

A: Do you make you hub motor “reverse”?

* If you make the three button switch to be “R”, bike motor will be reverse, the speed is slow. Make to “L”, bike motor will be forward.

Q:I have disconnected the three button switch and now seems to be working. The display when the ebike is in use does not go above 20 mph. does the display after you have set the mph/kmh mean ? It says p1, p2,p3,p4 and p5. What are the correct settings for these ?

A:Your electric bike kit can reach 40 mph without load, we test it. Even if you ride, still can reach about 35mph.
Please set the wheel size to be “26” It’s wheel size.
* Power on, turn on LCD, then press “up” and “down” button for 2 second together.
1. Then max speed will flashing. Make it to be max 72kmh.
2. Then “kmh or mph” will flashing. Press “up” or “down” to shift from “kmh” to “mph”. Then press “ON /in the middle of button” to done setting.
3. Then “wheel size,8,10,12,14,16,18,22,24,26,700 or 28” will flashing. Press “up” or “down” to shift. Make it to be “26” Then press “ON /in the middle of button” to done setting.

* After setting these 1,2,3. Then press “ON /in the middle of button” for 2 second. It will save these setting.
* After setting these 1,2,3.Then press “UP” and “Down” switches. Then start to set P1,P2,P3..

Don’t set P1,P2,P3,P4,P5
If make a mistake.

Please set it as below:

P1:46 (This hub motor has 46 pcs magnet,can’t set to other,it’s used to display correct speed)
P2:0 (That is low speed motor — without gears inside motor)
P3:1 (With pedal assist)
P4:0 (Start from 0 speed)
P5:15 (24V be 9; 36V be 12; 48V be 15)

Q: Great. After setting this P1, the hub motor works well. Correct, 40mph. Nice electric bike kit.

20 inch 1000watt or 1500watt front electric hub motor kit

Posted by on December 31, 2021 Comments Off on 20 inch 1000watt or 1500watt front electric hub motor kit

Q: I want to purchase a 20 inch electric bike kit front wheel for my rickshaw, I only ride it with my twin boys they are 3 years old. I obviously don’t want anything with a great top speed I and simply looking for some assistance on hills.From your 1000 watt hub motor wheels listed, it looks like your older design model has a top speed of 30mph so I am thinking that probably has the best gearing not the newer version which show 45mph. The 1500 watt hub motor motor appeals but again same thing only shows with high top speed 45mph…Can you please suggest the best front wheel electric bike kit for me. It has to be 20″ and
has a standard 100mm wide fork.

A: Our new version hub motor also have low speed. Also 1500w motor has low speed.You just tell us what speed would you like, we can do it for you.Our 20 inch front hub motor is fit for 100mm wide fork. Also we have 1500w front.

Q: then I would prefer to order the 1500watt hub motor, do you offer that in the 20 inch with cast hub or only spokes as can’t see 1500watt with cast hub listed. I assume the cast hub would be stronger than the spoke version and therefore better for rickshaw.

A: We have 20 inch spokes 1000w & 1500w front hub motor.We have these motors in stock.But caste hub,only 1000w,don’t have 1500 casted hub.

Q: I am still keen to go with the 1500 hub motor but the spoke version is has quite a narrow rim.I don’t suppose you could fit it with a wider rim, so I can use a 2 1/4″ or 2 1/2″ tyre or bigger would be now problem if you have them.Your standard rim states 1.5 – 1.95″ tyre which is a little small I want use a moped tyre because of weight on rickshaw and they are mostly all bigger than your standard rim.
