Ways to repair electric bicycles
Check the tightness of the chain before the electric bicycle is used. If the chain is too tight, the pedal is laborious when riding, and it is easy to tremble and rub against other parts if the chain is too loose. The sag of the chain is preferably 1-2mm, and it can be adjusted properly when riding without pedals.
If the tire pressure of the electric bicycle is insufficient, it will increase the friction between the tire and the road surface, thereby shortening the mileage; it will also reduce the turning flexibility of the handlebar, which will affect the comfort and safety of riding. When the air pressure is insufficient, the air pressure should be supplemented in time.
When the handlebars are not flexible in rotation, there are jams, dead spots or tight spots, they should be lubricated or adjusted in time. Lubrication generally uses butter, calcium-based or lithium-based grease; when adjusting, first loosen the front fork lock nut and rotate the front fork to the upper gear. When the handlebar rotation flexibility meets the requirements, lock the front fork lock nut.
Check the lights, horns, etc. before using electric bicycles, especially at night. The headlights should be bright, and the beam should generally fall in the range of 5-10 meters in front of the front of the car; the flashing frequency of the lights should be 75-80 times per minute; the instrument display should be normal.
Before traveling, check the electric bike battery power of the electric vehicle, and judge whether the battery power is sufficient according to the mileage of the trip. If the electric bike battery is not enough, it should be properly assisted by human riding to avoid under-voltage operation of the battery.
