a little problem with hub motor kit rim

I received bike conversion kit with new version LCD motor controller, hub motor wheel and bike parts ..everything but the lithium battery , started to mount a tire on the hub motor wheel rim and I think there might be a little problem with it the hole for the tube is in between where the spokes cross, making it almost impossible to get the inflation valve on the stem. I might be able to drill another hole on the other side between where the spokes go apart so it will work, haven’t looked into that yet the hole for the valve stem should be where the spokes are going away from it, so the valve can be fitted on easily. I have a few tools and a reamer so I probably can make it work. I was going to put one of these airless no-flat tubes in, its solid foam, but I think nice you get it on that’s it, you have to cut the tire to remove it after the tire wears out
I got a regular tube on and inflated it, but once it inflated the stem pulled so far down into the rim I get the valve back on it now.
I can’t get the valve back on, but it looks like it has enough air, hopefully it will hold it
anxious for the lithium battery to com now so I can try the motor out
I was looking at your metal case that the lithium battery goes in. on some other site it looked like the same case, but it had a theft vibration alarm when you turned the key and pulled it out, to keep it from being stolen. that looked like a good idea. I thought the theft alarm would be a good idea . The battery is so valuable. It might be a good idea for you to put one in the lithium battery case with a vibration sensor and maybe a 120db buzzer or something. the batteries are so expensive
I can see it being a good feature to add to all of the hub motor controller.
I think some sort of vibration alarm on the bike to detect tampering with such an expensive lithium battery would be a good product service for your customers
Be hard for them to run with the lithium battery when it is screaming at 120db they would be noticed kind of like a bump alarm on a car, when someone tries to break into it
I think going to find one for my recumbent bike conversion kit trick, the hub motor trick is worth over $2000 and now with the motor and battery another $1000
I am cautious about parking it even though its locked and chained down, someone might try and take the battery or hub motor controller off
I have a bracket under the seat with enough space to mount the plate and battery I think
that’s where they had one on another hub motor bike conversion kit at the dealer I bought the bike conversion kit from it was a low power motor and only 10ah lithium battery.
It would not pull the bike until you got moving about 5mph.Does the slipping plate come with the lithium battery case?
The hub motor they had on the electric bike at the shop was only 250w, 36v, it didn’t have enough torque to push the e-bike till you got it moving along with the pedals.

Leaf hub motor bike kit is working

Q: The bike conversion kit system is now working.
Still have some questions. It is about the brakes.
If we take the red and black wires from the scooter brakes and connect in parallel to the connection of the new hub motor controller, will this have a negative effect on the controllers? My friend thinks that this should not be a problem since this only brakes a circuit.

A: About that brake has two types.ONE is high voltage to brake.The other is low voltage to brake.
Ours is low voltage to brake,you should check your old hub motor controller whether that is low voltage to brake.
If you have volt-meter,you could get about 5V from red and black wires from your old hub motor controller.If it's 5V.That's no problem to parcellel.


Q: We finally got the chance to try the new bike conversion kit wheel after doing all the modifications except for the front brake which we still have to modify.

We have a new problem and I need your expertise. I tested the bike conversion kit wheel up the hill and on its own (without using the rear wheel motor). It went up the hill at about 17 km/hr……..which I think it is satisfactory.

However when I took it up a steeper but very short incline which is on my way home, the fuse connected to the batteries got blown (caput) and lost power (no electricity).

The fuse is gauged at 10A. What should I do to avoid blowing out the fuse? If I change the fuse to a different amperage, will this have negative consequences for the rear motor? Do you suggest anything different?

As always, appreciate your assistance.

A: When up the hill,the current will reach about 15A.If too steep hill,it will reach more than 20A.
20A-30A current is easy to break controller.
Sometimes 15A continuous current for about half an hour also can break controller that's because of too hot will break hub motor controller's MOSFET.

We suggest:
* Cool controller is important. 
* When you up hill,use two hub motors.On the flat road,use one motor.

Our hub motor bike conversion kit can't get any problem when your up any hill.But should cool controller.

Use 15A-20A fuse.Had better to use 15A.But if use 20A fuse,climb hill has more power.But we worry controller.

Electric hub motor and brushless dc controller information

Q: We are interested in using your bike conversion kit in this project, however, due to specific project requests, we have the following questions.

First question: Do you have any brushless DC controller which allows hub motor rotation inversion?

Second question: Could you send us some documentation containing information about the brushless DC controller for the 48V/1000W bike conversion kit ? (i.e. pin description) 

Third question: We have found two hub motor models over 1000W of output power (BLW-16B and BLW-20B) in your leaf motor website. However, in the performance datasheet of the BLW-16B, the maximum output power mentioned is 1037.32W. Is there any motor with output power of 2000W (we need to reach 60 Km/h)? Do you have a different brushless DC controller for these electric bike motors?  

Fourth question: We would like to use your LCD in our project. Is the LCD independent of the brushless DC controller? What are the inputs necessary to the LCD to display the information (speed, voltage, mileage etc.)?

A: We have 24V 250w, 36V 250w.36v 750w‚ and 48V 1000w LCD controllers to drive our brushless electric bike motors.

If you need 48v 1000w motor for e-bike. Generally, choice HBL motor.
That BLW-16B and BLW-20B are used for e-motorcycle, e-tricycle.
The power can reach 2000W, Speed:>60km/h    
The performance data you saw show Max 1037.32W.Because we test this BLW-16B through 48V 25A 9-MOSFET controller.
This hub motor had better to use 48V 15 MOSFET or 18 MOSFET controller to test.
Now we have 48V 15MOSFET BLDC motor controller to drive this hub motor, but no led.
BLW-16B and BLW-20B are the same hub motor, the difference between them is casted hub.
BLW-16B is 10 inch casted hub and uses 16 - 4.00 inch tire..
BLW-20B is 12 inch casted hub and uses 20 - 4.00 inch tire.

Our LCD must work with our BLDC controller, don't input anything. There is a signal wire to test speed. Just set the size of wheel.
When electric bike kit system works, LCD will display speed, battery gauge, mileage..

Q: Probably we are going to use the BLW-20B hub motor. We are designing an e-tricycle which should allow the driver to move back and forward. It means that we need a BLDC controller which allows the motor to rotate in two directions. Do you have a controller like this? In case you do not have, we are interested in using your LCD to a different controller (we have already found a controller that allows two direction rotation). Is that possible?

A: We have 48V 15-MOSFET brushless controller that can forward and reverse (two direction rotation),but No LCD now.
Now 48V 12-MOSFET can work with LCD, but it's hard to drive this BLW-20B when power more than 1000w hub motor.
Now few customers order this 48V 15MOSFET controller for bike conversion kit.

20 inch hub motor conversion kit for electric bike

Q: I have looked at your leaf motor and want to buy one bike kit includes hub motor wheel, BLDC motor controller and twist grip throttle. I am looking at a 20 inch wheel with 1000 Watt hub motor, but I think that one may not be enough to handle the load. I am looking to build a three wheeled vehicle and look at the possibility that I may need to power 2 or all 3 of the BLDC hub motor wheels to achieve my goals. I am thinking of building two or three of these three wheeled vehicles. What can you do to help? A: Thanks for you are interested in electric bike conversion kit . For my personal idea, use a 20" 1000w brushless hub motor to convert a front wheel, front drive is much better. If possible, order two sets of 20" 1000w BLDC hub motors with one high power brushless motor controller to convert two rear wheels - rear drive. It’s no problem with forward and reverse. But when you turn left or turn right, you will get a little trouble. Only under much lower speed can turn left or right. Convert two wheels that is enough. If you always ride on flat road, only convert one front wheel. Q: I was thinking the 20 inch 1000 Watt bike conversion kit as exampled. What I had vision was to use 3 BLDC motor controllers, but using one on front and one larger for the 2 rear hub motor wheels may make things easier. For turning it is easy to not worry about differential control on the rear wheels, such as turn radius larger than 5 M differential on the rear wheels is not consequential as centerline width is app 720 mm. It would be very easy to turn the inside wheel off by disconnect, or turn the rear drive off all together and let the front wheel do the deep turning. So what I need is real pricing for three sets of bike conversion kits includes three BLDC hub motors, two BLDC motor controllers. One 1000 W for front, and the other 2000 W for the two rear hub motor, or what is possible to have one 3000 watt drive to run three brushless hub motors? Please note that the vehicle will need a lot of power to traverse some of the steep ramps and terrain. It seems that the 1000 W hub motor seems to have app 17 Nm torque and that would mean that three would have just enough torque to carry the load. A: We suggest you order below bike conversion kits : 1.3 sets of 20" 48V 1000W hub motors (one for front, the other two for rear hub motor) 2.1 set of 48V 1000W LCD BLDC motor controller to drive front wheel, LCD display speed, battery gauge. 3.1 set of 48V 2000W brushless motor controller to drive two rear wheel 4.2 set of thumb throttle, one of left side to control front wheel, the other on right side to control right wheel(when turning, loose right side throttle, just twist left side thumb throttle) 5.1 set of brake lever to control three controller, when press lever, all of three controller will cut off power 6.1 set of three button switch used to control reverse, horn, lights Hub motor, BLDC motor, bike kit, bike conversion kit supplier: Leaf Motor Technology Co., Ltd Website:https://www.leafmotor.com

electric bike conversion kit battery

Q: After order hub motor wheel bike conversion kit with battery. When could you ship this electric bike battery . Is it only one blue packing plastic battery like the one you send me a picture of that one fix on to my frame I just need to hold it with zip ties. Dose this electric bike battery have a on and off switch. or is it a pack with like 2 battery's in a bag? 
A: This blue packing plastic battery doesn't have ON/OFF switch. Only frog/bottle style battery has this key or ON/OFF switch.
If you need 36V bike kit system, You can order frog/bottle battery.
Frog battery is easy to hold on your seat-post, don't need to drill two holes on your frame.
 We sell lithium battery, it's lighter."2 battery's in a bag" that is 24V sealed lead acid battery. It's very heavy and cheap.
Q: I didn't read the last sentence I don't want batteries In a bag because it is to big then I need the rack I don't like racks. I sent it from my IPod I drop it and catched it and I press the send bottle. So I was saying I don't like the rack, but with the blue packing plastic battery 48v 10ah  is it one pack or 2 pack that comes with the kit, and Connect to the controller. The one you Send is just one, it has 2 wires on each side is that the one that comes with the kit. and how can I turn it off and on the bottle battery is to big and long.
A: 48V 10Ah is one pack that is made up of many cells with BMS.
If we order our hub motor bike conversion kit and electric bike battery. We first to ship bike conversion kit in 24 hours. Any lithium battery should be customized as order. Because electric bike battery is different from other goods. It has use life. It takes about 7 days to customize.
There are one positive wire, one negative wire and one plug for a charger. Turn off should disconnect wires. Sure, also can connect a switch to control it(ON/OFF)
Q: There isn't the pass used for how hard you pedal, if you pedal hard hub motor will go faster. what about if I don't install the pas and I pedal will it go faster or will it go at the same speed, also if I install the pas can I still go fast with out pedaling, or do I need to keep on pedaling to go fast with the pas up hills. 
A: Our hub motor bike conversion kit can work with throttle/pas.
If both install throttle and pas.
1.If you pedal it, don't use throttle, pedal faster, hub motor wheel run faster.
2.If you twist throttle, don't pedal.Twsit more, hub motor wheel faster.
3.If you twist throttle and pedal together, only one decide speed.

When you ride on the road or up hills, most of time use throttle, don't need to pedal. Sure, if you need to do exercise. Please pedal more.

Spokes for hub motor bike conversion kit

Q: I ordered a 750W hub motor last month. Now I am going to fix a 20 inch bike motor wheel. Are there standard spokes with nipples I can order on leaf motor online anywhere as order bike conversion kit ? If so- where ( what ’s the standard, exact measurements ) ? If I order from you, what would be the price? A: It's very difficult to replace spokes for hub motor ,there are not standard ones. The length of spoke is lie on the dia.of hub motor and bike rim. Ours are double alloy rims,20" rim: eyelet to eyelet is 360mm. If you order rim and spokes with nipples,just costs $30USD,but the shipment costs $100USD Because the vol. of bike rim is very large. If you don't order bike rim, just order spokes with nipple, it’s very hard to done your bike kit. Why not order bike conversion kit directly ? Another way, you order 20 inch bike motor wheel with rim and hub. But without rotor winding. When you receive this hub wheel, you should disconnect your hub motor, take the rotor winding out of your hub, and put into this 20 inch wheel. This is the best choice. Cost less, easier to solve your issue. Q: I tried to take out a spoke and I was successful. I then tried to put the spoke back into the bike rim and I succeeded again. So I would like to order a set of spokes without the rim. How much would it cost? A: The price of 1 set of spokes is $10USD; The price of shipment by EMS is $50USD (USA or Europe) Total price:$60USD Q: Yes, I'd like to go ahead and purchase it. To double check : - Are nipples included? - Spoke (nipples) are for 20" rim (750W motor)? - How can I pay for it – PayPal ? What's PayPal ID (email)? A: I am not sure you can install them. We will send you a set of spokes (more than 36 pieces with nipples) You could pay on our website directly. www.leafmotor.com Q: I just sent you $60USD directly via PayPal (Transaction ID#28L39717XW247817D,date 25-May-2012)I couldn't do it from your website, so you will only see PayPal payment (may not see any order) A: Could you tell me your correct address and telephone that for shipment. We are going to ship out your products in 24 hours. You will receive below goods: 1.36 pcs spokes with nipples for 20" 750w hub motor bike conversion kit Bike conversion kit, hub motor, bike motor supplier: Leaf Motor Technology Co., Ltd
