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.

BLDC motor benefits in simple terms

BLDC motor (DC Motor) benefits in the speed control is relatively simple terms, the size of the control voltage only has control of speed, but the motor should not be in such high temperature, flammable and other operating environments, and because of the need to brush motor As a current converter (Commutator) components (brush motor), so they need regular cleaning of the friction generated by carbon brushes dirt. The brushless motor as compared to a brush, brushless motor because less carbon brush and shaft friction so more energy is relatively quiet. Made more difficult, the price is higher. bldc motor controller (AC Motor) can at high temperature, flammable and other operating environments, and do not regularly clean up the brush of the dirt, but in the more difficult to control speed, because speed control bldc motor controller must control the frequency of alternating current (or use of induction motors, with the increase in internal resistance in a manner that the same lower frequency AC motor speed), control the voltage will only affect the motor torque. General civil motor voltage 110V and 220V and other two, in industrial applications as well such as 380V or 440V type.

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)

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.

History of torque bldc motor controller

History of torque bldc motor controller
The late 1850s, the initial low-speed torque bldc motor controller is a pump stator and rotor components evolved, this component consists of a ring gear and one with matching gear or rotor component. The fixed ring gear and the shell can be connected together, the oil from the port into a center to promote the revolution around the rotor. This slow rotation of the rotor drive shaft through the splined output as cycloid bldc motor . This after the advent of the first cycloid motor, after decades of evolution, another conception of the motor began to form. This motor is installed in a built-in ring roller. With roller motor provides high starting and running torque, roller reduces friction, thereby improving efficiency, even at very low speed output axis can produce a stable output. By changing the input and output flows in the direction of the motor to quickly change, and such values ​​in both directions of torque. The series of motors have a variety of displacement were selected to meet a variety of speed and torque requirements.
