Bike troubleshooting method

If you find that the mountain electric bicycle is broken should be repaired, and that the first thing is to first find out the fault can be repaired. That general professional repair personnel in a short time how quickly determine the fault lies in where?
1, the electric car did not turn up
In the case of electric, open the electric door lock. Measured with a multimeter whether the voltage motor leads can immediately determine the fault lines and control lines. Bike specific measurement method is measured with a multimeter DC gear controller or motor leads, turn to the governor whether the voltage measured can find fault.
Measurement results are voltage, it is determined that: bad motor or controller circuit failure of the motor to the lead, should be excluded. No voltage measurements, it is determined that: control line failure, should the next check.
The controller brake power plug is disconnected, and then turn the power switch. Car rotating, it is determined that: the brake switch is bad, has been causing a short circuit fault, the brake switch should be renewed. If the car does not turn, then again a good to the governor, to replace the original turn to. Such as the car rotates, it is determined that: the original to the governor is bad, causing the foldable bike electric does not turn, should get a new controller.
Measuring the battery compartment contacts, the power supply section can be determined immediately because the car does not turn cause failure. It is to measure the battery contacts with a multimeter DC gear box, to see whether the voltage display. If no voltage display, find open power locks, dashboard does not light up, it is determined that: Fuse Fuse off, should be replaced by fuses, wires off, welding wire breakage or should be renewed. If voltage display, turn the power locks, dashboard light is off, it is determined that: power locks broken, no power to get a new lock.
2, the electric car stop switch
The speed controller regulator turn the plug off, it can be determined to the governor or controller failure immediately. If the plug is disconnected to the governor to open the electric door lock car does not turn, determine: the governor is bad, re-installed, repaired. If the plug is disconnected to the governor, open the electric door lock, the car still turn, determine: the controller is bad and should be replaced.
I know these things and then, in the face of a similar failure, if the situation is more urgent, then you can do it yourself repaired.

electric trike bikes which tips

electric trike bikes design standard load of 75kg, when the load exceeds 90kg, the battery and the motor will be damaged. Battery not long hold, hold charge at least once a month. After riding the battery discharge must be fully charged storage, otherwise it will greatly affect battery life, severe cases can cause the battery scrap.
When the power runs out, the system will automatically power off. But after the power is turned off, the electric bicycle battery appears bounce "virtual" voltage (reactive power and voltage), then it must be charged before using it, otherwise it will cause the battery discharge, which would damage the battery can not be repaired . Actual mileage continued line of cargo electric bicycles will be affected by many factors (such as frequent braking, starting, uneven pavement, the temperature is too low, on the steep slopes, wind speed, tires inflated, excessive load) effects.
When riding slow acceleration. From 0-20km / h, acceleration time is not less than 10S, in order to maintain a smooth ride. Minimize the number of starts. Electric vehicle economic speed (most power can travel speed) is generally 16-18km / h. Note that the braking distance riding is generally 4m, rain increases the braking distance doubled.

How to improve the electric vehicle battery capacity

In the electric vehicle battery case permit, try to increase the battery size. Increasing the plate thickness of the gate, the main positive plate thickness. Use this method to increase the amount of active substance, so as to achieve the purpose of increasing capacity. Thinning the plate thickness, to improve the utilization of the active material, increasing the number of plate sheet, plate area increase, so as to achieve the purpose of increasing the capacity.
Thinning the plate is more conducive to increase capacity, but because of an increase in the plate, positive and negative cargo electric bicycles increased interval, it will inevitably lead to thinning of the membrane, thereby increasing the risk of dendrite membrane penetration, while increasing the cast plate, coated plate, workload assembly. Both methods improve the capacity, we must increase the density of acid in order to ensure there is enough acid involved in the reaction.
Both methods currently made battery open circuit voltage is between 13.7V-14V (which is far beyond what we customarily acceptable value), 5A discharge all of 140 minutes or more.

Development of China's electric bicycle technology

China electric bike on the application of the torque sensor technology and integrated circuit controller technology has been a world leader, the integrated electronics and digital technology in the controller, the motor valve-regulated charge control other components, intelligent electric bicycles will be the future the commanding heights of development.
The high-tech composite materials and high-strength light alloy material will be more used in electric bicycles manufacturing. While the successful application of aluminum alloy material, the use of titanium, chromium molybdenum steel and other lightweight, high strength carbon fiber and other materials and polymer composites. Increase the intensity of electric adult tricycles, electric bicycles to reduce the weight. The bicycle's performance and manufacturing process revolutionary change.
Wider application of computer and microelectronics technology in electric bicycle product design, mold processing and production process, continue to improve production automation and improvement of production technology. Accelerate international new technology, new materials, the use of tires, batteries and accessories manufacturing nano materials, so 3 wheel electric bicycles are lighter, faster and travel farther.
China's nickel-metal hydride battery technology has gradually matured applications, lithium battery safety issues once solved, it can be spread. Technology leading electric bicycle manufacturing enterprises to increase research on new energy, reduce the cost of the new battery to the electric bike more "source of life."

Electric bicycle motor controller principle

Car fast motor controller pace of development in recent years, is hard to imagine, operating on increasingly "fool", and the display is more complicated. Drive connection, it also has an electric mountain bicycles performance and help functions, if the conversion to boosting state, with the chain tension dynamometer, or axis torque sensor, tandem electric bicycle pedal motion as long as the pedal, you can perform or help determine the booster's size.
The controller is a peripheral device and the main chip (or single-chip) components. SCM also called microcontrollers, are integrated on a single chip to memory, language has transformed signal decoder, sawtooth generator and pulse width modulation function circuit and make the power MOSFET switching circuits on or off, by side wave conduction time of the power control tube drive circuit to control the motor speed, integrated input and output ports, and the computer chip composition.
Design quality control, features, functions used in microprocessor, power switching devices and peripheral devices circuit layout is directly related to vehicle performance and operational status, also affect the performance and efficiency of the controller itself. Different quality controllers, used in the same car with the same state with the same set of battery charge and discharge, and sometimes show large differences in driving ability.

Electric folding Bikes

One of the issues with a standard electric trike is that they are rather large for storing and transport. Many seniors have downsized their housing which sometimes means less storage space. A trike that folds, and is Flyhorse Three wheel bikes  addresses this issue and opens the door to riding fun to even more people.
The addition of the electric motor means that your tryke is pedal optional. You can pedal for exercise or relax and let the motor do the work.
Battery operated bicycles all use a step through design making boarding much easier than a traditional bike. They also address the balance issue. The rider can go as slow as they like, without losing balance, and put both feet on the ground while seated. And now, with electric power bikes  you can pedal for some exercise, or sit back and let the trike do the work. How’s that for versatility?
Many retirement communities have limited car parking at strategic centers and will only allow golf cars. The down side of golf cars is you can’t take them on the street. There are few, if any, restrictions on electric bikes or trikes in most municipalities.

Battery powered bikes

The electric bike is a new kind of two wheeler: Our customers talk—above all—about the sense of joy, excitement and fun the actual riding offers, about their fascination with the foldable electric bikes unique ability to blend human and motor power, and that it offers most of the advantages of the Battery powered bikes and fewer of its shortcomings. The eBike—what is it uniquely?
Electric bikes are ridden by adults of just about all ages and proficiency, on differing rides and for varying purposes. More about who rides.
By law the electric bike is a 'bicycle', not a motor vehicle,battery operated bicycles if incorporating pedals and restricted to a 20 mph top speed and up to 750 Watts of power. More about the law.
