Q:You wrote me that there are no differences between HBL-36F1/HBL-F2/HBL-48F hub motor, so the different prices listed on your website are just for commercial reasons ?
I’m glad to hear you can supply customized products, is this possible even for small numbers ? (We are starting this type of business and at the beginning we will need just a few pieces).
I really appreciate your hub motors mainly for the technical
specifications provided rarely present for this type of product.
I would be interested in testing the following electric bike motor:
– HBM-Rear (diam.=145mm)
– HBL-Rear (diam.=243mm)
(No rims, no spokes, no custom products at this time)
However I would like to know if disc brakes can be mounted on these
motors and, as I have to make some particular tests, if you can supply both motors with a 12 (or 14) tooth fixed sprocket mounted on (I mean just a single fixed sprocket, not the classic freewheel gear).
A:Our HBM-Rear and HBL-Rear can both be installed disc brake and freewheel are fit for standard 135mm rear fork.
Please review picture”Disk-6in”.Does your Disk brake with this threaded adapter?If have,your disc brake can mounted on our motor.
If you this disc brake doesn’t have this threaded adapter,we will offer you this part.

check your electric bike conversion kit system
Received electric bike kit,but it doesn’t work.How to test this system?
When you put on your li battery,three leds on throttle should light together.If only red led is on,please check your battery.If your battery shows 59 volts and three leds is also on.But when you turn your throttle,only red led is on.The problem is from this EV battery.
Use a voltmeter to measure,supply power to your controller and measure as below:
1.Six-pin hall sensor connector(red,black,green,blue,yellow wires)
..The voltage between red and black wires is about 4.5V;
..The voltage between green and black wires is about 4.5V;(use your hand to turn the wheel,the voltage will change from 4.5V~0V)
..The voltage between blue and black wires is about 0V;(use your hand to turn the wheel,the voltage will change from 0V~4.5V)
..The voltage between yellow and black wires is about 4.5V;(use your hand to turn the wheel,the voltage will change from 4.5V~0V)
2.Three-pin connector to throttle(black,red,green wires)
..The voltage between red and black wires is about 4.5V;
..The voltage between green adn black wires is about 2.3V;
3.Two-pin connector to handle lever(white and black wires)
..The voltage between white and black wires is about 4.5V;
4.Two-pin connector to crusie(brown and black wires)
..The voltage between brown and black wires is about 4.5V;
5.Three-pin black SM connector is used for PAS.
6.1 pcs of purple wire should be connected to the positive of battery(It seems a lock)
7.Two grey wires are used for HALF/FULL speed.
If you can get these data,the system NO Problem.
Bldc stepper motor for electric bike
In the subsection of section Classification of electric bikes we looked at options for motors used in electric bicycles, their positive and negative sides.
Let’s try to analyze and compare the characteristics of electric motors (bldc hub motor and bldc stepper motor)from one well-known manufacturers: Leaf Motor (China).
Leaf Motor produces sets with a motor-wheels, and the other kits that use a chain drive.
The analysis will be based on data from well-known owners of electric bikes site EValbum, the characteristics of the manufacturer, and other sources on the Internet. Therefore all figures are approximate, and the findings are an expression of opinion ePowerBikes.ru
As stated by bldc hub motor, voltage motor-wheel independent maximum speed:24V – 25 km / h, 36V – 32 km / h, 48 V – 50 km / h. These data are confirmed by practical measurements elektrovelosipedistov. The maximum velocity at the start line set bldc stepper with 42 km / h and end with 120 km / h. Those cyclists who speed up to 30 miles is enough, can choose a motor-wheel 24V,36V,or 48V.
For practical information, electric bikes with a motor-wheel 36V 500W and lithium-phosphate battery 10Ach a maximum speed of 32 km / h and can cover a distance of 50 km. For those who want to ‘fly’ at speeds above 50 km / h, suitable set of Leafmotor 601kit-1 48V 1000W e bike kit.
Compare sets with the same maximum speed – 45 km / h – a new set 601kit-1 48V 1000W bldc hub motor and bldc stepper 48V 500W. Based on the characteristics of graphs,we choose the rate at which engines operate most efficiently, it is 40 km / h for both.
For the same power consumption in this mode – 420-440 watts, at the time of bldc stepper motor is a little more, but this is neglected. It turns out that energy costs are the same at a speed of 40 km / h. We obtain a theoretical figure 10.5 Wh / km, although in practice the number is likely to be greater. Now suppose that we face a steep hill. The maximum torque developed HBL hub motor – 30 Nm, bldc stepper motor – 38 Nm.
For the calculation we use a calculator elektrovelosipedista. Let Curb weight of a bicycle with the stepper motor – 100 kg, the rise of 7% of 3.5 km. To overcome this recovery time is needed more than 26 Nm on the wheel 26. ” Power expended by the motor-wheels 601kit-1 e bike kit is more than 1060 W at a speed of 35 km / h. Total energy costs – 106 Wh.
What makes it with bldc stepper-kit? He switched to the lowest gear, increasing time and decreasing the rate of 2.4 times (for cassettes with a maximum star 34t). At 2600 revs / min, torque on the shaft of the gearbox – 11 lb lost by power – 390 watts, speed – 14.5 km / h. Cost of energy to overcome lift – 94 Wh. Switching gears allow the rider to use the bldc stepper with the maximum efficiency of ~ 83% versus 73% for motor-wheels 601kit-1. As you know, the availability of transmission system for a bicycle greatly expands the range of effective use of a set of bldc stepper motor. These are one of the best available right now,s o if your´re looking for one, check it out. 9-14 cassette on the wheel 26 “will change the torque of 6 to 60 Nm and a speed in the range of 11.5-45 km / h (about 2100-2900 revs / min) at an efficiency of above 80% (included efficiency gearbox and chain drive). Efficiency of the motor-wheels 601kit-1 has a maximum value of 78% of torque 10-16 Nm.
It is logical that upon arrival at the ideal surface Bonneville Salt Lake in Utah, at 40 km / h, both test sets will spend the same amount of energy. But as soon as the trial will move to an area with hilly terrain, a set of bldc stepper will be more economical than 601kit-1, and of course will be able to overcome the ups who his opponent will not under force.
We note again that the higher efficiency is achieved when using leafmotor’s bldc stepper motor in the range of maximum efficiency, extended thanks to gear bike.
Bike kit=bike motor+motor contorller?
With gasoline price ↑ day by day,more and more bike fans from Europe and North America would like to convert their bicycle into electric bicycle, because of some reasons,it’s necessary to convert by their selves:

The interest in electric bicycles and other Light Electric Vehicles (LEVs) is exploding as gas prices rise across the globe. LEVs are perfect for those who are tired of sitting in traffic or being cramped into crowded public transportation. But with any major purchase, be sure to do your research. Here are 3 things you should keep in mind before making your purchase.
As gas prices rise across the globe, so does the interest in electric bicycles and other Light Electric Vehicles (LEVs). These LEVs are perfect for those who are tired of sitting in traffic or being cramped into crowded public transportation. But like any major purchase, it’s worth doing right. Here are three things you should keep in mind before making your purchase.
One of the first questions you’ll face when upgrading to an electric bicycle is whether to buy a separate bicycle or upgrade your current one. To upgrade your current bicycle, you can purchase a motor kit designed for this purpose. This might seem intimidating – but don’t let it be. All the best electric bicycle motor kits come with easy-to-follow installation instructions. Installation is quick, too. You could get your kit and be riding your new bike in the same day. For those who prefer to be hands off, there are plenty of options for buying ready-to-go bicycles. Both of these options function just like a normal bicycle except with some extra battery assistance. You won’t be getting the same speed and power as you would from a motorcycle.
Know Your State’s Law
If you’re planning to purchase an electric bicycle to use in the United States, you need to be aware of your own state’s laws. Most states hold up the national policy that electric bikes must operate under 20 mph and have a limit of 750 watts. However, the companies who produce these bicycles are not regulated. This means they could produce a bicycle or motor kit that could be illegal. Also, most states don’t require you to get special insurance for your electric bicycle as you would need for a regular company. But you’ll want to check the Internet for any changes in policy that might occur. Since electric bicycles are relatively new, the laws and regulations around them could change very quickly.
Choosing a Battery
When purchasing an electric bicycle or a motor kit, you’ll come across various options for the battery power. More than anything, the choice of battery depends on how you will be using your bicycle. Riding in hilly areas or adding additional weight by pulling a trailer will drain battery power faster. Your best selection would be a Lithium Ion (Li Ion) battery as it surpasses all other battery types in the number of recharge cycles it can go through. Basically this means that you can go longer without having to purchase a new battery. Also, just like all other batteries, these batteries come in different voltages. Though the higher voltages will cost you more money, they will last longer and perform better, we offer you including financing assistance.
Purchasing an electric bicycle for the first time can be a confusing experience. However, deciding whether you want a new bike or a motor kit, knowing your local laws, and choosing the best battery for your needs will help you make the best purchasing decision possible.
Electric bike for fun
Amid today’s high gas prices and concerns about global warming, an electric bike is an economical and sensible choice. And beyond that, it’s downright fun.
As gas prices soar and concerns grow over global warming, alternative fuel vehicles are gaining traction. When it comes to cars, trucks, and SUVs, a hybrid is currently the most popular alternative to a gas powered engine, you also have to make sure you use the best which for me it has always been Oneureinsurance and an accident lawyer, just in case. If you need new tires for your truck, you can get your truck wheels online. In addition, visit services for more information. I do business. But when it comes to short-range commutes, say 20 miles or less, an electric bike is a fun, economical, and environmentally friendly option. For only pennies, an electric bike can get you from place to place without breaking a sweat and without the hassles of traffic congestion.
An electric bike has pedals like an ordinary bicycle, and you can use those pedals to propel yourself under your own power. But the electric bike also has an electric motor, which you can use to augment your pedaling. The supplemental power is useful when starting from a stop or when riding against the wind. Alternatively, you can let the electric motor provide all the power while you sit back and enjoy the ride. This makes an electric bike one of the most versatile vehicles around. There are even models of electric bikes that fold up for easy storage or travel, as well as recumbent electric bikes, which will take bicycling to a new level of relaxation (just don’t fall asleep at the wheel!). Just in case of a truck accident, call for legal advice and counselling. Get he best professional lawyers here.
An electric bike can be purchased as an off-the-shelf item, or you can purchase bike conversion to convert most any bicycle to an electric bike. The important factors to consider when selecting an electric bike are battery life (which determines how far you can travel on a charge), speed, and durability. Today’s electric bikes take advantage of recent advances in battery technology. Many electric bikes are powered by nickel-metal-hydride or lithium ion batteries, which can give a travel range of one two hours. Most electric bikes are capable of reaching speeds of 10 to 20 miles per hour. Durability is an important consideration, and like anything, you get what you pay for. You can spend under $500 for an electric bike, but the quality may disappoint you. The better quality electric bike can be purchased for around $500 to $1000. Check your local laws, but generally there is no registration required for an electric bike.
