battery operated bicycles disc repair

Determine runout is caused by what . Inspection methods: support from a large front wheel off the ground , light hand turn the wheel, find much resistance areas. That point grinding disc , battery powered bicycles marked with a red marker . And in the three bolts marked 1,2,3, serial number , and remember the original installation location.
1 , remove the front wheel . Then remove the battery powered bikes disc . This is the most troublesome , is a bit difficult , screwing the bolt must be struck with a hammer in front of three hexagonal , or hexagonal plate wring also screwed down.
2, the discs get clean , put on a clean glass , the disc without side down stairs . With a thin piece of paper next to the hard disc plugs, as are stuffed into, explained the disc is not deformed , said Mingrui face runout caused by the wheels .
3 , the Electric Bicycles disc must be relatively flat deformation . This is not difficult , you have friends in the machine shop of the most easy.
4 Wheel Swiss uneven surface will use the compensation method . That method in 1.2.3 plus sheet position among the added sheet , the sheet is cut into the skin of cans ( thickness 0.12MM). Combination of the above grinding disc plus point to determine the location of the sheet , depending on everyone's analyzes .

battery powered bikes several advantages

With the rise in oil prices in recent years, battery operated bicycles industry wells:
The following briefly say the advantage of battery powered bikes:
1 low price, nice
2 operating threshold is low, no driving license, driver's license.
3 high security performance, when speed is not more than 50KM, maximize reduce accidents,
4 battery tricycles closed, convenient travel, the elderly and children to reduce wind and rain
5 green, pollution-free.

How to quickly find faults battery powered bike

  Repair of Flyhorse battery powered bikes in two steps, namely, troubleshooting and repair. The premise and the key is to quickly find fault repair.
 First, the car does not turn (ie, the motor does not rotate)
    1, the use of electric vehicles detector test whether the voltage of the motor leads can immediately determine the fault lines and control lines. Measurement result is voltage, then determine: bad motor or motor controller to the lead circuit fault and should be excluded. No voltage measurements, it is determined: control line failure, the next step should be checked.
     2, the brake controller plug off, and then turn the power switch to. Turn the car, then the judgment: brake switch is bad, has caused a short circuit fault, you should get a new brake switch. If the car does not turn, you then transfer to a good governor, replacing the original transfer. As the car rotates, the judgment: the original to the governor is bad, causing the electric car does not turn, should get a new controller.
     3, measuring the battery compartment contacts can be judged immediately by causing the car does not turn the power section of the fault. If no voltage is displayed, turn the power locks, dashboard lights are not lit, determine: Fuse Fuse broken, should be replaced by fuses, wires off, welded wire breakage or should be renewed. If the voltage is displayed, turn the power locks, dashboard light does not shine, it is judged, power locks broken, the lock can be renewed without electricity.
 Second, turn on the power lock, turn the car stop (surprise car phenomenon), brake car
     Detection method is to control the speed regulator turn off the plug, can be determined to the governor or controller failure immediately.
 If the plug is disconnected to the governor, open the electric door lock car does not turn, determine: the governor to have been bad; If you disconnect the governor put the plug, open the electric door lock, the Flyhorse battery electric bicycle still turn, determine, control is already bad and should be replaced.

"Dehydration" corrupted the battery powered bikes battery

"Dehydration" is one of the basic reasons for reduced battery capacity. The vast majority of Flyhorse battery powered bikes using lead-acid batteries are maintenance-free, many users say that the battery is sealed and maintenance-free, and why there is "water loss" phenomenon? Its reason is simple, the water is an important component to participate in the Flyhorse battery operated tricycle battery electrolytic reaction occurs once the battery overcharge, large current discharge, resistance increases, short circuit, etc., prone to heat and the formation of water vapor, water vapor in the sealed battery compartment would be to retain the majority, but there are very few parts will be lost (due to the battery casing material density determined), the passage of time, the battery will be "dehydration" state. Generally, the electric vehicle battery will exist more than 6 months "dehydration" state, the greater the motor power, "dehydration" state more serious.

After the plug-in battery powered bikes battery design

Design: design concept originated in Japan, due to the original design uses a nickel-metal hydride batteries, so the layout is very lightweight and beautiful.
Advantages: Keep the big bike features traditional curved beam, in line with the rider off the habit, consistent load habits.
Cons: Compared with the general 24 inches wheel diameter models, Flyhorse battery powered bikes size significantly lengthened to 1780mm, 200mm longer generally about the size, it is actually the size of the battery casing together, giving a great sense of bovine high horse, less than one meter tall by 65 feet easily touch the ground; Flyhorse battery power bicycle load is more concentrated in the latter part of the stability somewhat less; while oblique beam height and center of gravity similar to that once propped easily overturned; somewhat troublesome when handling batteries , the highest point of the need to turn off the folded cushion organs, while the battery needs to take place to complete from the ground 1050mm, height less than 160cm women difficult to achieve.

Battery powered bikes lead battery plate curing corrupted

What is the battery powered bikes battery sulfide? A white board in a very hard lead sulfate crystals, while being very difficult to transform the charge of the active material of lead sulfate, which is sulphated, referred to as "curing." The reason generating such long lead sulfate is placed over discharge or discharge, the lead sulfate particles dissolve in the electrolyte, was saturated, the lead sulfate crystals at low temperature again, and is in a crystalline precipitate of lead sulfate. Such particles are deposited on once again and again due to temperature changes in the growth, development, and the crystal grains increases. This lead sulfate poor conductivity, resistance, solubility and dissolution rate is very small, difficult to recover the charge. Thus a reduction in capacity and lifetime becomes shorter reasons. Sulfide is the main crux of the battery capacity decrease, but the current injury is the electric vehicle battery plates larger battery capacity to reduce the crux.

Battery powered bikes mileage is not the greatest long relationship with what ?

Electric cars with mileage is not long should the battery , controller, motor , frame, tire contact area with the ground , tire size , big route.
In fact , brake adjustment , quality bearings , oil is good or bad , good or bad shock , models drag design , aerodynamics, sit -owned angle , the proportion of front and rear wheels , tread , tire type is also a relationship.
What is the continuation mileage, fully charged battery powered bikes can travel many kilometers ?
" Continued mileage " refers to the maximum number of miles after a full charge , the electric car can travel under normal conditions . Under normal load and speed , the electric car to continue the mileage of 50 kilometers, up and down about 5 km away .
Of course , the impact of continuation of many factors Mileage : If the battery Condition: a new set of batteries , the actual " continue the mileage " may be more than 50 km , while using his cell for some time , " continues the course " will declined. This is mainly due to the increased use of battery capacity with time and declined. In addition , the actual load weight , the road is flat , with or without the downhill , wind speed , wind direction, moving the brake , a combination of factors the number of starts , tire adequacy of gas, and the correct charging method , the use of ambient temperature will affect the actual " continued mileage "in length . The faster the car , the faster electric loss , riding the same amount of power to run a little slower to walk farther .
