The use and maintenance of electric bicycles

1.Before using an electric bicycle, the height of the saddle and handlebars should be adjusted to ensure riding comfort and reduce fatigue. The height of the saddle and handlebars should vary from person to person. Generally, the height of the saddle is suitable for the rider to reliably land on one foot (the entire vehicle should be kept upright), while the height of the handlebars is suitable for the rider to have their forearm flat and their shoulders and arms relaxed. But the adjustment of the saddle and handlebar should first ensure that the insertion depth of the pipe and the riser must be higher than the safety sign line.
2. Before using an electric bicycle, check and adjust the front and rear brakes. The front brake is controlled by the right brake lever, and the rear brake is controlled by the left brake lever. The adjustment of front and rear brakes should be suitable when the left and right brake lever reaches half of the stroke to reliably brake; The brake pads are excessively worn and should be replaced in a timely manner.
Before using an electric bicycle, the tightness of the chain should be checked. When the chain is too tight and pedaling is difficult, it is easy to shake and rub against other components if it is too loose. A sag of 1-2mm is more suitable for the chain, and it can be adjusted appropriately when riding without pedaling. When adjusting the chain, first loosen the rear wheel nut, screw in and out the left and right chain adjustment screws evenly, adjust the tightness of the chain, and then tighten the rear wheel nut again.
Before using an electric bicycle, the lubrication condition of the chain should be checked. Feel and observe whether the chain shaft rotates flexibly and whether the chain links are severely corroded. If there is rust or the rotation is not flexible, an appropriate amount of lubricating oil should be added, and in severe cases, the chain should be replaced.
Before riding an electric bicycle, it is necessary to check the tire pressure, handlebar steering flexibility, front and rear wheel rotation flexibility, circuit, battery level, motor working condition, and whether the lights, horns, fasteners, etc. meet the usage requirements.
