Leaf 26 inch 48V / 52V 1000W electric bike conversion kit

Posted by on December 31, 2021 Comments Off on Leaf 26 inch 48V / 52V 1000W electric bike conversion kit

Q: I’m interested in leaf product of New 26 inch 48V / 52V 1000W electric bike kit (Item ID #LBCK26481000FN), and having some question as below.

1. Does the bike conversion kit already include regen function?
2. Is it possible to have a demonstration YouTube video to show me the E-ABS regen feature?

3. Do you have magnetic switch instead of Item ID #LBP002BL braking lever, because my current braking lever is an All in one type ?
4. As everyone knows the transportation cost is very high, if I can arrange the rim by myself from USA, can I modify order as following to reduce some transportation cost?
I want to make sure everything is the same as #LBCK26481000FN bike conversion kit besides 26 x 1.95 inch rim. (The hub motor, controller, LCD display, braking lever, three button switch, throttle etc…)

A: This New LCD controller has regen brake, cruise, reverse function…Also can use 1 pcs of brake lever, Not two. If possible, you also can use a ON/OFF switch to control. We ship 26 inch parcel by EMS express that charge shipping cost according as Net weight.

Q: My both brake levers are all in one type, so if I replace any one of them, I’ll lost front or rear gear shift function. I tried to calculate the total price by your leaf bike site. About the max. speed limit setting by LCD display, we can adjust any speed as we want, or only three setting mode can be choose?

A: This 48V New LCD is different from that old LCD, this new can set Max speed:(0 – 73kmh) any you want. That old LCD only set three speed mode.

Q: I always ride a route which includes a lot of up and down hills, the longest one is a continuity down hill for 2 km. It’s a 7% downhill, if you don’t use brake to reduce speed, the bike speed will be up over 45km/hr, so I always use brake to control speed within a safety area( within 30km/hr), but after through the downhill, the rim become very hot, it very bad situation. That’s one of many reasons that I want to put a bike conversion kit with regen braking function in my Bike. According my description as above, is your electric bike kit suitable in this case?

A: When you brake, the power will cut off. It’s easy to stop when you down hill. You will get new version of LCD display.

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.

question about one of your front hub motor for my electric bike

Posted by on December 29, 2021 Comments Off on question about one of your front hub motor for my electric bike

Q: I am interested in the 20 inch 48V 1000W hub motor electric bike kit – front wheel but I need to know what the front dropout size this hub motor wheel will fit. I have a small folding bike that has a front dropout of 74mm and need a 20 inch hub motorized wheel that can fit it. Any help you can give me would be great.

A: One of our 20 inch 48v 1000w hub motor (all black color bike motor) is fit for the spacing of 100mm front dropout.
The other 20 inch electric bike motor 48v 1000w (black color with silver motor) is fit for the spacing of 90mm front dropout.

Q: Do you have anything that can fit a 74-80mm dropout? It does not have to be 1000w. I am now looking for a 36v 250w electric hub motor kit?

A: Generally nearly all standard front fork is 100mm dropout. So all of our front electric hub motors are fit for 90-100mm.

Does your front fork is 80mm dropout?
Sometimes,when your wheel is on the bike,if you measure it the dropout may 80mm, because of two side screw nuts are be tighten.If you remove this front wheel from front fork,the dropout may be bigger,actual it also standard 100mm dropout.

Could you take a picture with your bike?

Question about 16 inch electric hub motor kit

Posted by on December 29, 2021 Comments Off on Question about 16 inch electric hub motor kit

Q:I thank you very much for UPS tracking number. The parcel should be delivered to me these days. Perfect.

Anyhow – I have one question regarding capable Li-Ion-battery pack for “16 inch, 36 V, 250 W front hub motor – electric bike kit, Item No. LBCK1636250F” which you shipped to me.
I have already one Li Ion-Battery pack; 36 V, 504 W, 14 Ah. Is that Li-Ion-Battery pack suitable for using with E-Motor I ordered from you?

A: Just connect your battery to our controller, it works.

Q: You shipped to me in Oct. 2018 “16 inch, 36 V, 250 W front hub motor-electric bike kit, Item No. LBCK1636250F”.
Today first, after buy of kick bike scooter (not pedelec), I install complete kit on my kick bike scooter and it works not. Display works normally (battery indicator full) but it is no E-Motor Watt-indication and no E-Motor reaction after switch on gas-accelerator (speed adjustment not 0 but 1 till 5).
After check of all delivered Parts from your Company and received Datasheet, I discovered some discrepancies:

1. Which voltage has E-Hub Motor, 36 V or 24 V ? (See attachment Page 2/6 and Page 3/6 as well as Page 4/6 with Photo1)
Remark: Delivered E-Motor has no technical dates described on the motor alone.
2. “Cruise button (red/green as shown on the Page 4/6 its other one; See Photo 2)
3. Delivered controller has another dimension as shown on page 4/6; See Photo 3)
4. Which are correct installations codes to be installed for P1 till P5 and C1 till C14?

Awaiting your response asap of the above questions and your statement above delivered kit. Thanks in advance.

A: controller works with 36v battery (min 30v to max 42v)

Please check if there is “-O-“ on the middle/ top of screen.. If have, the system is braking… please disconnect brake lever’s plug or make brake lever’s ring be back. Then motor works.

Please check the blue wire of three button switch if cut off. If cut off blue wire, that’s okay.. If no blue wire cut off, must push the yellow button the other side, motor works. (The yellow button on your picture that works backward status. This motor Not support backward status. So not work)

29 inch electric hub motor kit have problems with the cassette

Posted by on December 28, 2021 Comments Off on 29 inch electric hub motor kit have problems with the cassette

I ordered the 48v 1500W electric bike kit, with cassette.
I have problems with the cassette, the cassette is wider than where the dropouts sit around the axle.
So the hub motor wheel with the cassette on is wider than 135mm.
My bike frame is 135mm, and the website said it would fit on a 135mm frame.
When the cassette is on the hub motor wheel and i put the electric bike motor wheel on the bike, the frame grinds against the cassette when I tighten the electric bike motor wheel.
I have made it work using spacers so it spins freely, but the wheel is offset to one side now and i think my frame is spread wider. It is an aluminium frame.
Also the website said max 7 speed gear, but the cassette is for a 9 speed gear, which is also mounted now, is it suppose to be able to take a 9 speed gear, or is that an accident?
Any advice on what to do?
Also, any advice on mounting the torque arms? My frame is aluminium.

Steel is okay.But Aluminium is not good to make it larger. We worry if make aluminium frame to larger will break frame.
We recommend use 7 speed or 6 speed or single speed..

You will receive below goods:
1x pcs of 29 inch 48v 1500w rear hub motor wheel (black spokes, cassette)
1x pcs of 48V bldc motor controller (New version LCD controller)
1x pcs of LCD (New version LCD-003)
1x set of twist throttle
1x set of brake levers
1x pcs of three button switches ( use to control cruise,reverse..)
1x set of pedal assit ( It’s fit for European,if you don’t use,ONLY use throttle is okay )
Some spare spokes with plugs

——————————————-
How to set max speed?
If you feel motor is too fast,please set it to be low speed.
* Press “sw/middle button” from LCD more than 2 seconds,then LCD will display.
* Press “up & down button” together more than 2 sconds until 72 is flashing ( 72 is kmh, if you hope works 20mph / 32kmh, press “down” to be 32)
* Press “sw/middle” button one time to save,then 29 is flashing.. (29 is wheel size. Don’t set)

Product Question of New 26 inch 48V 1000W electric bike kit – front wheel

Posted by on January 1, 2021 Comments Off on Product Question of New 26 inch 48V 1000W electric bike kit – front wheel

I’m interesting your product of New 26 inch 48V 1000W electric bike kit (Item ID #LBCK26481000FN), and having some question as below.

1. Does the kit already include regen function?
2. Is it possible to have a demonstration YouTube vedeo to show me the E-ABS regen feature?
3. Do you have magnet switch instead of Item ID #LBP002BL braking lever, because my current braking lever is an All in one type (braking lever and Shimano in one)?
4. As everyone knows the transportation cost is very high, if I can arrange the rim by myself from USA, can I replace order as following to reduce some transportation cost?
I want to make sure everything is the same as #LBCK26481000FN besides 26×1.95 inch rim. (The hub motor controller, LCD display, braking lever, three button switch, throttle etc…)

1. I always ride a route which include a lot of up and down hills, the longest one is a continuity down hill for 2 km.
it’s a 7% downhill, if you don’t use brake to reduce speed, the bike speed will be up over 45km/hr, so I always
use brake to control speed within a safety area( within 30km/hr), but after through the downhill, the rim become
very hot, it very bad situation.
That’s one of many reasons that I want to put a E-BIKE with regen braking function in my Bike.

According my description as above, is your e-bike kit suitable in this case?

4. Is the attached photo new version or old?
Do you mean that if I place order with #LBCK26481000FN kit set will get new version of LCD display?
If place order with LBC481000L 48V 1000W bike motor controller will get old version of LCD display?

When I downhill, if I release throttle and turn on the E-ABS by switch, but I don’t push the brake lever to make mechanical brake working. will bike glide freely and very fast? is the controller charging battery at this moment?

Normally when E-ABS turn on, the speed should become lower as below, is it right?

When a very long distance downhill (the same gradient),
if freely glide down (without throttle, mechanical brake, E-ABS), the invariable maximum speed is 35km/hr
when turn on E-ABS only, the invariable maximum speed should be lower than 35 km/hr, such as 25~30km/hr

Check your hub motor wheel – electric bike kit

Posted by on June 11, 2020 Comments Off on Check your hub motor wheel – electric bike kit

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 handle 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.

Please 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.
