After being braked, the gap between the brake handle and the grip cover should be a finger distance. Parallel to the brake part of the wheel rim, the deviation of the up and down, left and right is the same. 11. How to checkbrakeIs the power-off device intact? Hold up the bracket, open the switch, turn the right turn handle, start the motor, and then gently hold the left brake handle. The motor should be able to power off immediately and gradually stop rotating. If the motor cannot be powered off at this time, stop the drive and ask a professional to repair it before using it. 12. What aspects should be paid attention to when inflating the front and rear wheels? l) Inflation method: After inflating to a certain air pressure, turn the rim to knock the tire evenly with your hand, and then continue to inflate the tire to match the rim to avoid slipping during riding. 2) Inflate properly, too much will cause violent turbulence when driving, too little will affect the speed and load of the car, and will cause the tire wall to crack,Inner tubePierced. 13. What is the recommended torque of the key component fasteners? The recommended torque of the cross tube, the stem, the saddle, the saddle tube, and the front wheel is 18N.m, and the recommended torque of the rear wheel is 3ON.m. 14. How to judge the battery Electricity? Each electric bicycle is connected with a battery power indicator. According to the indicator, the battery power can be judged. Note: The smaller the depth of discharge of the battery each time, the longer the battery life, so no matter how large the capacity of the battery pack, you must develop a good habit of charging as you use it. 15. Which parts of the circuit and connectors need to be checked? Before leaving the car, check the electrical plug of the battery box, whether the polarity seat is shaken, whether the electric door lock is flexible, whether the battery box is locked, whether the horn and light buttons are effective, and whether the light bulb good. 16. What is the height adjustment of the saddle? The height adjustment of the saddle of the electric bicycle is based on the fact that the rider's feet can touch the ground to ensure safety. 17. Can electric bicycles carry loads? The design load of electric bicycles is 75kg, so if you remove the weight of the rider, you should avoid carrying too heavy objects. When carrying a heavy load, use pedal assistance. 18. When should the electric bicycle's electric door be opened? To ensure safety, please open the electric bicycle's electric door when getting in the car. When parking or driving, the electric door should be closed in time to prevent unintentional rotation of the handle and cause the vehicle Suddenly start up and an accident occurs. 19. Why do electric bicycles with zero-start function need to pedal when starting? Electric bicycles with zero-start function consume more energy due to the larger current when starting at a standstill, and are easy to damage the battery. In order to extend the battery life after a single charge For mileage and battery life, it is better to use the pedal first when starting. 20. Why use pedals to assist when going uphill? Electric bicycles consume the most energy when going uphill, so pedals are recommended when going uphill. 21. What are the hazards of using the motor to start the handlebar and the brake handle at the same time during driving? Although the electric bicycle has a brake power-off interlocking device, it is still necessary to avoid the use of the motor starter handle and the brake handle at the same time to prevent the motor from overloading and damaging other parts. 22. What should I do if I encounter uneven or steep roads? Electric bicycles are not suitable for driving on the above roads. If the vibration is too large, it will cause poor contact of electrical devices. In this kind of road, please slow down or get off the car as much as possible. 23. Why use pedal power when riding in winter? When riding in winter, the capacity of the battery pack is reduced due to low temperature. The same riding distance will increase the depth of discharge. Using pedal power will help extend the battery. Service life. 24. What to do if the vehicle is still powered on when the motor is turned on and the handle is loosened? In this case, turn off the switch immediately and use the pedal riding function. The vehicle should be sent to a professional maintenance department for repair. 25. What range of electric bicycle speed (Tempo) should be controlled? The maximum speed of electric bicycle is 20km/h, but the wind resistance consumes a lot of energy when driving for a long time, which affects the continuous mileage of one charge, so it is recommended that the speed should be controlled at 15 --18km/h is better. 26. How to maintain the battery? 1) Keep the battery away from flames, heat sources and alkaline materials, and avoid direct sunlight (Sunbeam), otherwise it will shorten the battery life. 2) A special charger must be used to charge the battery to avoid damage to the battery. 3) Charging time: 6 hours in summer and 8 hours in winter. 4) After driving in summer, due to the high temperature of the battery, it is not advisable to charge it immediately. It is in Celsius in winter. Below 0°C, the battery is in a low temperature state, and charging should be done indoors. 5) The used battery, if left unused, must be fully charged and stored, and recharged every month or so to ensure the service life of the battery. 27. What aspects should be paid attention to when charging? 1) When charging the battery, insert the charger output (low voltage) plug into the socket of the battery box, and then insert the charger power supply and plug into the 200V/5OHZ AC power supply, and charge at this time The charging indicator on the panel of the charger will light up. After the charging is completed, the charging indicator will turn to a floating charging indicator, and the charger will automatically switch to low current charging. If the plug is not unplugged in time, it will not cause harm. 2) Do not wash the car body with battery box with water when charging. 3) The charger should maintain good ventilation and heat dissipation conditions. 4) When the battery needs to be charged, it can be charged on the body of the car, or the lock of the battery box on the car can be opened, removed from the bicycle rack, and taken to a place with a power source for charging. 5) Turn off the switch when chargingswitch. 28. How to replace the fuse? If the motor does not rotate, please check if the fuse is blown first. If it is blown, just replace the fuse with a new one. The fuse must be replaced with a fuse core of the same specification. It is strictly forbidden to replace it with a copper wire or iron wire conductor to avoid unnecessary losses. 29. Why should electric bicycles avoid sunlight and rain? Although electric bicycles have good rainproof performance, in order to prevent short circuit of electrical devices, they should still avoid direct sunlight and rain.
