electric bike conversion kit has a very big advantage

1886, when the world’s first gasoline car invented a four-wheel, its 18 kilometers per hour to run, but also when the carriage speed, many people laughed at the “monster”, but some far-sighted people such as Karl Ritter • Buddha Li Qi • Mercedes-Benz, Ford, etc., but insight into their vision for development and actively involved in this industry, which achieved a lot of great car company. 100 years have passed, and now, another change will occur in the car – electric bike conversion kit has been coming to us, such as the face of such changes, semiconductor suppliers, how to choose?

“Infineon to enter the field of electric bike conversion kit has a very big advantage, electric bike conversion kit with a major difference between traditional car is built on top of a set of high-pressure system, and we have been in the field of high power devices occupy a leading position.” Recently, a press conference at Infineon, Infineon’s Automotive Electronics Division electrically driven, product line director Mark Munzer stressed, “In addition, we are the world’s largest supplier of automotive semiconductors, so that we can just combine the two expertise up and applied to the electric bike conversion kit, we can provide the best to the bike conversion kit solution. “He seems to corroborate discussion, we note that in the 25th Electric Vehicle Conference, only a Infineon exhibitors and other semiconductor suppliers leading supplier of automotive electronics were not participating.

Similar to long term loans online approval, unsecured loans consist of multiple lines of credit that have no use of proceeds requirements. Whether you need to pay for working capital, construction or pay a franchise fee, unsecured loans can help.

Now, with rising gasoline prices and gasoline vehicles environmental pollution, electric bicycle conversion kitinstead of increasing demands for high gasoline vehicles in China, and some even shouted “Stop petrol cars by 2015,” and other slogans, however, countries The Government has increased the electric car does on the support, China, for example, June 2, 2010, Chinese Ministry of Finance, Ministry of Science, Industry and Information Technology, Ministry of National Development and Reform Commission has finally issued a joint “regarding the development of the private purchase subsidies for new energy vehicles pilot notification “(hereinafter referred to as” Notice “) to determine in Shanghai, Changchun, Shenzhen, Hangzhou, Hefei and other five cities to start private purchase of new vehicles to subsidize pilot energy, electric vehicles the maximum subsidy per 60,000 Yuan, plug-in hybrid maximum subsidy per 50,000 yuan. In addition, the Chinese government and other public transport electric bus has also given large subsidies, these policies will undoubtedly greatly boosted the confidence of the global market for electric vehicles, because China has become the world’s largest car consumer, the consumer behavior on the global automotive market impact is very large.

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

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.

Technical problem with a 20 inch 48V 1000W bike kit – problem solved

Today I hit in a technical problem with the 20inch 48V 1000W bike conversion kit (Item ID:#LBCK20481000FN). I was riding for a shorter distance steep uphill in level 5 and suddenly the bike motor was making an obscure humming sound and was vibrating very strong. So I stopped immediately and shut down the system. I checked the hub motor and the cable for overheating but they where just with normal temperature. After a while, I already turned to go back downhill, I started the system again but the problem still exists. It seems that it is maybe a problem with the controller because now there is no reaction in changing the power level (1-5) or turning the throttle on. The hub motor gets only around 10 Amps with a max. of 590W (measured with a installed Amp/Volt meter in between). When starting pedaling or with the throttle with low speed the vibrations are immense but when I gain more speed the vibrations are reducing to a lower level but they are still there. When staying still and pull the throttle full, so the tire normally can spin free, only the vibrations and a loud humming sound exists. I know I do not have any warranty more leftover on this system but maybe you have an idea how I can repair this for a budget price.

I already solved the bike conversion kit system problem.
Funny what unexpected small things could cause some different technical reactions. The problem of the bike conversion kit problem above was, that one of the 3 phase cables to the motor was broken. By the effect of the depicted problems above I really thought that something in the controller was burnt-out but happily I could find the broken cable very soon so now everything
works fine again.

26 inch electric hub motor kit for the dropout 160mm fork

Q: Are you able to supply a rear hub motor kit wheel (36v @ 500W – 750w) for a rear dropout of 160mm?
I have an existing e-bike that uses a 250w geared rear hub drive on a 26 x 1.95 wheel.
It has a 7 speed gear, standard 160mm disk brake and a bike mount (frame) width of 160mm.
I would be happy to go from a geared (small hub) to the larger electric bike motor kit type.
The existing bike frame is steel (not carbon or an alloy) so I may be able to ‘bend’ the rear forks… (fit).
I have included a PDF diagram (attached) to show the existing rear hub motor fitting size.

A: Yes, we have dropout of 160mm 36V 750W electric bike motor.

Q: With the new Leaf controller and LCD, I know I can limit the maximum output speed of the 750w Direct Drive hub motor to a set (safe) maximum speed for each PAS mode 1 – 5.
With our Australian laws, I want to honor speed and safety – yet have a safe speed and torque (reserved) for hills.
I respect that you have kindly supplied my order with a 320RPM hub motor ( a good choice).
My question is: “Does the max speed by set by LCD / Controller economically limit the maximum current sent to the hub motor”?
I am talking here about battery life with a low speed LCD / Controller setting ‘modulating’ the full power sent to the hub motor.
So if I program the setting to say 25Km/h, then is the torque output effected at speeds less than the given 25Km/h?

A: Yes, if you set max 25kmh by LCD, motor will work less than 25kmh.(You can set max 10kmh,11kmh,12kmh….48kmh,49kmh,50kmh)

1.Press “SW” from LCD. Turn on LCD
2.Press “up” &”down” together for more than 2 seconds in 3 seconds after LCD display – Then “72” will flash.
3.Press “down” or “up” to set any max speed. Press “SW” one time to save. Then “26” will flash. It’s tire size. Don’t set. Still press “SW” one time to save. Then “kmh / mph” will flash. Don’t set. Press “SW” one time to save.
4.At last, press “SW” more than 2 seconds, then will be back.

There is a Three button switch inside parcel.

** Black switch (be Left side / Middle – motor works forward. Be right side, motor works backward/reverse)
** Red switch (Be left side / regen off. Be right side / regen on)
** Green switch ( When motor is working, press this green switch one time. LCD is display C, motor will work as the same speed) – Re-press this green switch one time, or press brake lever, turn throttle to max, motor will stop.
