What is the best bicycle Electric Bicycles

Simply speaking is both light and strong , and the performance is better . With these conditions because it folding bicycle was easy bike ride , safe and convenient . But to achieve all of the above conditions , you need good material . So, bicycle parts is often a specific factor about bike prices. The best is to be able to participate in the Olympic Electric Bicycles race bike parts . Regardless of the strength properties of the weight or the best materials are used .

Transmission What are the Electric Bikes

General use of bicycles in the city , in fact, there are many slopes in the city. For example, you can Electric folding Bikes sometimes feel the pedal cyclist suddenly sink , with your eyes can not determine the slope often more. At this point , the role of transmission can be fully reflected, if there is transmission , it can be replaced at this time as long as the lighter gear to ease the ride. Of course , the same can be used when the wind . Advantage lies in the transmission , which can help you in case of physical prowess , effectively reducing your physical exertion . For Cargo trikes example, when the cold , physical exertion is not too large, so I chose lighter than the number of teeth will be very easy if you ride when riding . When the female body as well as the poor , tired student exam , older persons can flexibly use speed bike . Therefore, the benefits of shifting the car really is too much.

Trends Electric Bikes

Due to differences in national living standards, the Electric scooters purpose of using a bike is different, in some countries the rider to travel , exercise and sports for the children's primary purpose , the general use of multi-speed cars, sport utility vehicles and mountain bikes ; bicycle in some countries primarily as a means of transport , more use of light trucks and multi-speed cars. Overall, the bike is moving in the United States , light , fast , new , inexpensive direction. Beauty is beautiful shape, colorful, ornate and impressive ; Light is light weight, riding light ; prison is high cargo bike intensity ; new is new styles, varieties ; Lim is a low cost and competitive. Chinese elderly hobby cycling has hundreds of thousands of people , they set up bike riding around the organization , you need a group for the elderly riding travel , exercise bike, now double bicycles, recumbent -style bike has been developed came out.

What speed electric vehicles and related parts

Maximum speed of the electric car depends on the rated motor speed , you can limit the output voltage to limit the output speed , can be transferred to the output terminal plus two resistor divider in the Hall , if accuracy is not required , you can also signal line plus one to two diodes ( with controller sensitivity related to the Cargo bike experimentally determined ) . How can we know the brush motor brushes changed ? Generally when the brushes wear to 1/ 3 of the time, he should be replaced, the motor does not turn bad brush Fortunately , afraid of bad is good sparks serious damage commutator segments , then more harm than good , so the motor carbon brush should be life management . With a 240 -watt motor, battery is 36V20Ah, but the car Folding electric bikes starts, the power indicator pointer will point to the lowest level , but the car is not enough power, I ask this question about where is not just with a controller on the line of ? What kind of controller like this should be used , there is no good controller is recommended . Common causes of this phenomenon in general , there are two : the line impedance is too large, there may be various circuits joints bad .

What is the lead-acid battery sulfation causes and hazards?

After the formation of lead sulfate high activity over a period of time, if there is no timely charge within this period of time, or charging is not complete, so that it does not translate into timely positive electrode active material, will again lead sulfate crystallization temperature is low, the crystalline precipitate of lead sulfate, this was repeated again and again, increasing the crystalline particles become poor conductivity, it is difficult to dissolve, when charging is difficult to recover lead sulfate crystals, known as irreversible salinization (manual refer to such alleged Electric Tricycle salinization salinization). There are many, such as an electrode grid corrosion fatal, severe deformation of the grid electrode, the electrode active material falling off, the battery internal short circuit or battery failure CAUSE Electric folding Bikes physicochemical, however, statistics show that battery failure majority are by the electrode active material caused irreversible sulfation.

Connect electric normal . Is this why ?

1 phase angle may be wrong. Song is the degree of control is not written above 120 degrees , write degrees is 60 degrees.
2 Santroll matching controller is not very strong , especially rare motors on the market , so for another just fine with .
3 may be a phase when you start wiring wrong, jitter weakness and other phenomena, who rode to put the controller burned , so you do not turn up later then how can you be sure that the Battery powered bikes controller burned. Before wiring , the first to detect motor Hall is good or bad , angle, winding and magnet motor is normal, then use the accompanying controllers, such as voltage , current limiting , angle , phase , etc. The key is to be consistent with the angle of the motor controller , otherwise they might forever . Motor angle detecting very simple , as long as there are three high three Hall signal is low, that is 60 degrees, the controller detects an angle relatively quickly and accurately with the instrument . After the above work , electrical wiring 60 degrees within 10 minutes and 120 degrees within one minute to get the motor . 27 , and the line on the color phase motor problems on the green on the motor , blue, yellow, in the end what is the Three wheel bikes representative of each phase ? Some places to see A, B, C phase , and sometimes see is W, V, U -phase ? Most standard A, B, C phase is represented by what color , with green, blue , yellow, how correspondence ? There are green, blue , yellow, three -phase line controller coarse , sometimes with 3 phase motor is completely linked by color , simply can not be transferred , and why ? Many plant previously used this provision : A- Yellow , B- Blue , C- Green . Latest national standard " electric bicycle motors and controllers" ( draft) 4.6.1 states: motor terminal A- blue , B- Green , C- yellow. Hall outlet color requirements with the motor. A --- U, B --- V, W --- C motor factory in order to do some changes in the electrical outlet different colors, with matching controllers for each manufacturer had to change the way the outlet . 28 , brushless controller detects stall current, battery cathode series digital multimeters, clamp meter Cece any other motor with a thread , both the current reading is inconsistent, digital clamp meter multimeter relatively large in terms of many , why ? Power input current to prevail . Motor current is pulsating , not easy to measure accurately , in addition to

Electric Bicycle (electricbicycle)

To the battery as an auxiliary energy, with two wheels, to achieve human riding, electric or electric-assisted bicycles special features. Technical requirements:
1. Maximum speed: should not electric trike exceed 20km / h; ("Exchange Act" 58 stipulates that the maximum speed of the electric car is not more than 15 km)
2. Vehicle Quality: not more than 40kg (including battery);
3. Foot traffic capability: You must have a good ride pedal function, 30min foot travel distance should not be less than 7km;
4. Continued mileage: After a charge to continue the mileage should not be less than 25km;
5. Maximum Ride noise: the maximum speed for electric uniform riding (electric assisted to 15km / h ~ 18km / h speed electric Three wheel bikes assisted riding) noise should not exceed 62dB (A); 100km energy consumption should not exceed 1.2kW · h;
6. 100 km power consumption: with electric ride (electric power to electrically assisted cycling), the power consumption of 100km.
