Folding bicycles, the choose and buy

Folding bicycles to choose 3: hand weigh. From the electric trike material, mainly include the aluminum and steel. Millet, you often need to carry the car up and down building, it is recommended that you choose the product, aluminum frame, such a car in 10 kilograms, mostly 20-inch generally do not more than 12.5 kg. Is not only light weight, and aluminum frame products also lived longer, not rust. Of course, don't ignore the strength of the frame, some manufacturers are on the weight, in fact they are by reducing the thickness of frame to reduce weight, difficult to Folding electric bikes the frame has enough strength. Best riding around on the spot, not only can feel the frame strength, but also can test the vehicle body mechanics design is reasonable, good design can guarantee the riding position stretching, even long distance will not fatigue. Four: folding bicycles, the choose and buy brand recognition. Folding bicycles, due to the folding part can be activities, therefore requires corresponding parts when riding with solid and reliable performance, the frame should pass special design, has a higher strength than ordinary bicycle. You must by professional manufacturers to design and manufacture. Less known and inferior brand car manufacturers often in pursuit of high profits, in such aspects as, material, spare parts, the design of the lacquer that bake to cut corners, after-sales service is not certain. So consumer is when the choose and buy, should choose well-known enterprise product as far as possible to ensure your safety.

The composition of electric scooters

Electric motorcycle components include: motor, battery, charger, turn to, brake handle, power sensors, lamps and lanterns, display instrument, various work unit to complete the task. Motor used in electric vehicle, the mechanical structure, speed range, and there are many kinds of form of electricity. Common are: brush brush gear hub motor, no gear hub motor, brushless Three wheel bikes hub motor, brushless gear hub motor, side to hang and so on. Now in general use machine has two kinds, one is the rare earth permanent magnet motor, the other is a rare earth permanent magnet Folding electric bikesmotor, these two motor which a better quality, which mainly involves using performance, service life and maintenance cost. The internal structure of the permanent magnet motor it for disc rotor, containing carbon brush, the motor speed is 3000 RPM, must through the matching speed reducer, such as clutch reduced the speed to 180 r/min, to drive vehicles moving.

Charging ways, first time after go home, regardless of age, all want to charge, keep the electricity pool in the condition of sufficient electricity use, if occasionally didn't charge the battery, but often is not full of electricity use, the battery will create a "memory", affect the line continuation mileage, also the service life of the battery. Charge when you plug plug of the battery, and then insert the plug. End of charging, first pull the plug, pull out the battery plug again. Secondly, launch electric vehicles, avoid large current discharge, reduce the manned exercise, climbing the best human implementation or power line, otherwise it is a big damage for the battery. If the vehicle in the open air or cold storage for weeks when not, should remove the battery, stored in a warmer room, to prevent freeze damage to the battery. And try to shorten the use of electric vehicles at low temperature, and should be recharged in a timely manner. If you are not ready to use in winter storage battery, don't keep in the coming year when using rechargeable batteries, and it should be every 1 month to charge one battery, to ensure the storage capacity of lead-acid electric pool, at the same time avoid acid damage to the battery. Maintenance personnel said maintenance charging battery will remember to frequently, more power. In use after six months, the best to do a battery maintenance maintenance station, appropriate complement battery electrolyte, adjust well the proportion of the electrolyte, and check the electricity situation, keep the battery electrolyte proportion, can increase the number of charging when necessary. At the same time, clean the terminal of the battery, and painted with special grease to protect it is also very important, practical and reliable this can ensure that the electric car startup, extend battery life.
