(6) Electric bicycles must have an instruction manual with the following content
(1) Before reading the instruction manual carefully and understanding the performance of the electric bicycle, do not use the electric bicycle or lend it to anyone else. A person who knows how to operate an electric bicycle rides it.
(2) The tightening torque should be recommended for the fasteners of the handlebar cross tube, handlebar riser, saddle, saddle tube and wheel: attention should be paid to the safety lines of the handlebar riser and saddle tube.
(3) Lubricating parts, lubrication cycle and recommended lubricating oil.
(4) Correct chain tension and adjustment method.
(5) Brake adjustment and brake pad replacement suggestions. Pay attention to increasing the braking distance when riding in rain or snow.
(6) Correct use and maintenance methods of motors, controllers and batteries.
(7) How to use the charger correctly and safely.
(8) Technical parameters and performance indicators of Appendix A of GB/17761-1999 standard (standard appendix).
2. Precautions for the use of electric bicycles
(1) The operating requirements of electric bicycles must be followed.
(2) The standard design load of electric vehicles is 75kg. When the load exceeds 90kg, the battery and motor will be damaged.
(3) The battery cannot be left alone for a long time and should be charged at least once a month. After the cycling battery is discharged, it must be fully charged and stored. Otherwise, the service life of the battery will be greatly affected, and in severe cases, the battery may be scrapped.
(4) When the power is used up, the system will automatically power off. However, after the power is turned off, the battery will have a rebound "virtual" voltage (reactive voltage). At this time, it must be charged before use, otherwise the battery will be over-discharged, and the damage to the battery will be irreparable.
(5) The driving range of electric bicycles is 40-50km. In actual use, the driving range will be affected by many factors (such as frequent braking and starting, uneven road surface, low temperature, going up steep slopes, driving against the wind, under-inflated tires, and excessive load capacity).
(6) Pay attention to the display of the front instrument. After the power is turned on, the vehicle is in an electric riding state, with the red power indicator light glowing, and the green and yellow battery indicator lights glowing at the same time. As the power is consumed while riding, when the green light and yellow light go out, it means that the battery power is about to be exhausted. At this moment Electric riding should be stopped and the battery recharged as soon as possible.
(7) All preparations must be made before riding to ensure riding safety.
(1) It is strictly prohibited to get on and off the bus while in place. To ensure the safety of users, it is strictly prohibited to get on and off the bus by sliding.
(2) The power lock switch can be turned on after getting in the car. The power lock switch must be turned off before getting off the car.
(3) When adjusting the height of the saddle and handlebars, be careful not to expose the safety lines on the saddle tube and seat tube.
(4) Accelerate slowly when riding. From 0-20km/h, the acceleration time is no less than 10 seconds to maintain smooth driving.
(5) Try to reduce the number of starts. The economic speed of this vehicle (the most energy-saving driving speed) is generally 16-18km/h.
(6) When riding, please note that the braking distance is generally 4m, and double the braking distance in rainy days.
(8) The tightening torque of the handlebar horizontal tube and handlebar riser is 16-18N.m.
(9) The tightening torque of saddle and saddle tube fasteners is 18-20N.m.
(10) The tightening torque of the rear wheel is 40-45N.m; the tightening torque of the front wheel is 18-20N.m.
(11) The front brake skin should be parallel to the pressure surface of the wheel hub and the height should be consistent. The gap between the brake skin and the wheel hub should not be greater than 3mm; the brake tightness should be such that it can brake when the brake lever is held 10mm away from the handle. When not braking, the brake pads must not come into contact with any part of the wheel. When the brake pads are obviously worn, they should be replaced in time to avoid damaging the rim.
(12) The spokes should be tight and the chain should not collide with the car body. When adjusting, the distance between the rear wheel and the central axis can be adjusted, and the chain tension is controlled to 10-15mm.
(13) It is prohibited to add lubricating oil to the rear wheels.
(14) The tire pressure should be appropriate. If it is too high, it will cause the aluminum ring to deform; if it is too low, it will cause the outer tire to crack and bite the inner tube; it will cause the inner tube to leak.
(15) Pay attention when charging:
(1) First insert the output end of the charger into the charging socket of the battery, and then connect the input end to the power supply AC 220V .
(2) When charging, the red indicator light on the charger lights up, indicating that charging is normal. Before full charging, the green indicator light will be on. It is best to charge for 1-3 hours after the green light is on.
(3) After charging, unplug the AC power supply first, and then unplug the plug connected to the battery.
(4) It is prohibited to connect the charger to the AC power supply without charging for a long time without charging.
(5) The battery box can be removed for charging, or it can be charged directly in the car.
(6) If the battery box is taken out for charging, be sure to lock it when putting it back after charging to prevent the battery box from loosening and causing a power outage.
(7) It is strictly forbidden to open the power lock of the electric bicycle when charging directly on the car to prevent the charger from burning.
(8) When charging, the surrounding environment should be ventilated and fire-free. Be sure to use a charger that meets the configuration. It is strictly prohibited to disassemble the battery box without authorization.
(9) When the charger is working, it should be kept out of the reach of children to avoid danger.
(10) Handle it gently to avoid vibration.
(16) Try to prevent the motor from starting at zero. It is best to ride manually before starting the motor to avoid excessive current from zero starting and affecting the life of the battery, motor, etc.
(17) When riding on rainy days, care should be taken to prevent water from entering the controller and motor, causing short circuit damage.
(18) When climbing hills, going on bridges, or driving against the wind, excessive battery power supply current will affect the life of the motor and battery. At this time, it is best to ride with human assistance.
3. Electric bicycle maintenance
(1) Motor maintenance and upkeep
(1) The bicycle has been installed and debugged to the best condition before sale. Please do not disassemble or assemble electrical appliances and related parts at will. If you find that the transmission parts make abnormal noises or do not work when powered on while riding, you should ask a professional maintenance technician to repair it.
(2) The motor does not require adjustment or maintenance during normal use. It only requires some cleaning work such as surface dust removal. Never add lubricating oil to transmission parts at will.
(2) Maintenance and maintenance of the battery
(1) When the red undervoltage indicator light on the instrument panel lights up, it indicates that the battery has entered the starvation zone and should be charged in time. Prompt charging will greatly extend battery life. Fully charge the battery once a day and each charging time should be 8-12 hours. Keeping the battery fully charged at all times is of great benefit to its lifespan. If it is not charged in time after riding, the service life of the battery will be greatly affected. Serious cases may cause the battery to be scrapped.
(2) When starting an electric bicycle, it should accelerate slowly; when driving on a steep slope or against the wind, it is best to use pedal assistance to avoid large current discharge of the battery and extend the life of the battery and motor. . And can avoid burning electrical components.
(3) When the battery is not used for a long time, it should be stored with sufficient charge and should be recharged for no less than 24 hours every three months.
(4) The battery should be charged in an environment with good air circulation. Avoid getting close to fire sources. It is best to remove the battery pack when charging to facilitate heat dissipation.
(5) The optimal working environment temperature of the battery is
15℃-40℃. Outside this temperature range, the normal operation of the battery will be affected.
(6) Do not short-circuit the positive and negative terminals of the battery to avoid danger.
(7) Only the special charger provided by the manufacturer can be used for charging.
(8) The battery is a special battery. Please do not use it as a power source other than for electric bicycles to avoid damage to the battery.
(9) Organic solvents cannot be used to clean the battery casing. In the event of an accidental fire, carbon dioxide cannot be used to extinguish the fire. Instead, fire extinguishers such as carbon tetrachloride should be used.
(10) If the battery pack fails, please send it to the manufacturer's authorized office or relevant organization for proper handling. Please do not throw it away randomly to avoid environmental pollution.
(11) When the ambient temperature is higher than 40℃ or lower than -10℃, the battery life will be shortened. Therefore, when the temperature is high in summer, the battery should be kept away from direct sunlight. During low temperatures in winter, batteries should be stored indoors and charged indoors.
After the battery is fully charged, charging should be extended for another 2 hours.
(12) When the ambient temperature is -10°C, the battery can only discharge 60% of its power. Therefore, the driving range of a full charge in winter is much less than that of a full charge in summer. In winter, it is better to use foot-assisted driving when driving electric.
(13) Batteries are consumables and their lifespan is limited. The end of battery life should be assessed based on the fact that the mileage once fully charged can only reach half of the national regulations (25Km). That is, the battery life ends when the driving range is less than 13Km after a full charge, and the battery should be replaced with a new one.
(14) It is strictly forbidden to expose electric vehicles to the hot sun for a long time in summer.
(3) Maintenance and maintenance of the controller
The controller has been adjusted to the best condition when the electric bicycle leaves the factory. If an electrical failure or loss of control occurs while riding, non-professional maintenance personnel can only check the cables and connectors. If the fault cannot be eliminated, they should contact a professional maintenance point or manufacturer immediately.
