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 Our paypal account: sales@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)

electric hub motor for motorcycle

Q: I am planning to install hub motor on my gasoline scooter. Basically I want my scooter to use gasoline or electric hub motor. My question is, if I install the electric hub motor on my scooter.

What will happen to the electric hub motor (motor is off) if I run my gasoline motor top speed of 120kph? Will the electric hub motor (even turned off ) be damaged because of higher wheel rpm on gasoline running top speed?

A: If max speed is less than 800RPM that is no problem for our hub motor.
What size of your wheel?
Too high speed will break the bearing.

Q: If I change the bearing to high speed bearings. Will the coils magnet inside will break? 17 inch rim.

A: Magnet and coils is no problem if you cut off electric so that No current between controller and motor when you use gasoline.
If No current, Not too hot. Magnet and coils is okay when 120kmh.
17 inch rim. I think you should use our 20 inch bike conversion kit.
Below leaf bike is our new site.

Q: I saw your youtube videos on your channel.
I prefer to install it on front wheel using a 17inch motorcycle wheel rim,so a hub motor is best. You can checkout my motorcycle channel youtube.com so that you have idea on what I do on my bikes.
What kind of hub motor can you suggest on me?

A: We recommend 20 inch front 48V 1000W hub motor with 160mm disk. The diameter of this electric hub motor tire is about 51cm. It’s brushless gearless motor and has enough power to climb on ebike. We found yours is motorcycle, it’s too heavy. If possible, please choose our 17 inch electric motorcycle motor. It’s very fit for your motorcycle. How about this 17 inch electric motor?

I just placed a hub motor kit order on leaf bike site

Paypal confirmed payment of $1201.00 USD for order Transaction ID: 9CG1909M41791512C
The other day I was trying to services when I decided to order a 20″ front hub motor wheel 48V 1000W custom bike conversion kit along with a 48V 20AH LiFe2PO4 battery. I chatted with a representative the other day about some questions about what was included with the electric bike conversion kit and that it would be suitable in the application of use on my 3 wheel recumbent tadpole trike. Your representative said you could include some items free of charge since my order is over $1000 USD.
I asked if the 48V 20AH lithium battery was just wrapped in blue shrink wrap as depicted or if it came in a locking metal case like the 12AH battery and he said that you would find a suitable key locking metal case for the 48V20AH battery similar to the 12AH one and include that Free of charge.
I asked if the bike conversion kit included a torque arm since it was not listed in the items on the page and i thought that since it most would be required with a 1000w hub motor it should be. He said the kit would include 2 torque arms free of charge.
I see on the pages it appears that the black lightening is all black and the other styles in some kits has silver rings on the outside of the hub motor. The kit I am ordering looks like it is all black in the picture so I assume it is the new more powerful Black Lightening, but I would like to confirm before the item is shipped which style/model of hub motor this is.
Your representative also said you would include 2 of the 3 button switches, and since it is not clear whether the thumb throttle or twist throttle would be the most practical with my recumbent trikes steering you would include one of each free of charge.

How to disconnect the bldc hub motor for electric bike?

Spring come,nice days to ride e-bikes.But when you take out of your old e-bike from warehouse and are going to ride it.Suddenly you would find there is strange noise from hub motor .
These days the electric bike motor are brushless gearless and used for electric bike widely.It was made of rotor-winding,magnet,hub,covers,axis,bearings…
If this bike motor has strange noise,generally it’s from rotor-winding rub magnet or the bearing is broken.It’s easy to solve it.The important is to disconnect this electric hub motor.
You should prepare some tools:
1.Hexagon wrench (Necessary)
2.Hammer (Necessary)
3.Screwdriver

Disconnect hub motor Step 1:
Take off nuts and gasket on axis and use hexagon wrench to loose 16 screws.

Step 2:
Make the hub motor stand and cable is bent inside.Left hand hold the hub motor and use hammer to knock the axis.

Step 3:
After some knock,the cover will take off hub.

Step 4:
Use the same way to knock the other axis,the other cover will also take off hub.

Step 5:
When both side covers are off hub,next we should take out the rotor-winding.Make the axis stands on the ground,both hands press hub motor,the rotor-winding will out of hub.

Step 6:
Check magnet around inside hub,if there is some metallic impurities stick on magnet.Please remove it.If no,but found some friction trace on magnet.Please check around the rotor-winding and remove some glue around the steel.If not,please check the bearing inside the cover.Use a little finger hold inside the bearing,use the other hand to turn cover,faster,better.If you hear some noise.Please replace bearings.

By now,you have solved problem.

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.

After all this hard work I’ve done with the bikes I think I need to celebrate this.

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 where 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.

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!

electric bike conversion kit accessories

SHIMANO the difference between the various levels accessories riders often asked the difference between SHIMANO parts of each level, each verbal explanation, that is not professional, would like to get hold of writing, first in the online search, I found that did not write very detailed, and Many of the old models, or for something to do shows that can be very responsible, said a careful reading of this article, after you when choosing SHIMANO parts can definitely ease, what they had. 1: What is SHIMANO electric bike conversion kit? The main production departments SHIMANO bike bicycle speed, transmission, brakes and other accessories, we usually referred to as electric bike conversion kit, including: front derailleur (front derailleur) after derailleur, (rear derailleur), variable speed lever (mountain has taken a turn to, DIP, dual control handle these types of forms; road has changed hands (STI Dual Control lever) and DIP), the first sprocket (tooth plate), rear sprocket (flywheel), chains, hubs, brakes, and related to a variety of transmission lines & pipes, brake lines & tubes & accessories oil and so on. Two: SHIMANO each grade electric bike conversion kit ‘s Name: SHIMANO sport level mountain off-road electric bike conversion kit, from low to high name followed by: TOURNEY; ALTUS Acera ALTUS; Acera ALTUS Acera; ALIVIO; Deore; Deore LX; Deore XT; XTR; lower C050, SIS and the like civilian variable is not included, in addition to HONE (ranging between XT and LX for heavy XC and AM); SAINT (ranging between XTR and XT, for in the AM and FR); for BMX in DXR, capreo with less, but also temporarily explored. SHIMANO exercise level road with electric bike conversion kit, from low to high name followed by: 2200, SORA, TIAGRA, 105, Ultegra, DURA-ACE; lower for the civilian A050 and SIS were not in this column. Three: SHIMANO each grade electric bike conversion kit for grade orientation highway: DURA-ACE is the top competition level, Ultegra known as the professional training level, 105 is a professional entry-level, TIAGRA an amateur level, SORA is the entertainment level, 2200 be regarded as entry-level entertainment . This is a watershed in which 105, 105 (or more) can be called professional grade. Mountain: XTR is the top competition level, Deore XT is the top training class, Deore LX is the professional training level, Deore is a professional entry-level, ALIVIO is the top entertainment level, Acera and ALTUS are entertainment level, TOURNEY regarded as entry-level entertainment. Deore is a watershed, Deore (or more) can be called a professional. Above the level of points is more vague, so-called entertainment that is specific to non-travel by riding movements, fine grading again the following four: SHIMANO grades electric bike conversion kit as detailed difference now (February 2007) SHIMANO all levels electric bicycle conversion kit model for mountain: TOURNEY; ALTUS (M310); Acera (M340); ALIVIO (M410); Deore (M530 disc brakes for the M535); Deore LX (M580 disc brakes for the M585); Deore XT (M760 disc brake for the M765); XTR (M970 disc brakes for the M975); Another HONE (M600; SAINT (M800) highway electric bike conversion kit: 2200, SORA (3300), TIAGRA (4500), 105 (5600), Ultegra (6600), DURA-ACE (7800) only discuss the detailed comparison of these new models, starting from the details of each part more, read the will understand the various grades in the end worse off. ?????? Mountain: TOURNEY strictly speaking not a complete set of electric bike conversion kit, it is the entry sport to support the positioning of 6 / 7 speed Acera and ALTUS no significant difference between the price difference is small, can be simply understood as the same level, Acera main configuration 8-speed, and Acera 7-speed and ALTUS main configuration (in fact, they can be compatible with 7-speed and 8-speed), the relative TOURNEY, an increase of 8-speed support, Acera rear dial connection pin on which a sleeve fluorine coating, wear resistance, smaller and more.
