Pay attention to cleaning first, especially when encountering water, especially when it comes to salt water in winter (many cities spray salt water to avoid freezing after heavy snow in winter). It is even more important to clean it in a timely manner, otherwise it can easily cause metal parts to rust and paint film to age and fall off. The second is to pay attention to the maximum adjustment height. After riding a new car for a period of time, check and adjust the whole car according to the requirements of the manual. Tightening and lubrication are essential at this time. Check if all fasteners are loose and if the transmission components are flexible. After lubricating the chain with oil, wipe off the floating oil and apply a little oil to the flywheel. Tire inflation should be appropriate, otherwise it will affect the comfort and service life of cycling. The brake is a basic guarantee of safety and should be checked at any time. Any problems found should be immediately adjusted or repaired.
1. Before using an electric bicycle, the height of the saddle and handlebar should be adjusted to ensure comfort and reduce fatigue. The height of the saddle and handlebar should vary from person to person. Generally, the height of the saddle is suitable for the rider to be able to reliably land on one foot (the entire vehicle should be basically upright), and the height of the handlebar is suitable for the rider to have their forearms flat and their shoulders and arms relaxed. However, the adjustment of the saddle and handlebar should first ensure that the insertion depth of the pipe and the vertical pipe 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 the front and rear brakes is suitable for reliable braking when the left and right brake handle handles reach half the stroke; The brake shoe is excessively worn and needs to be replaced in a timely manner.
3. Before using an electric bicycle, the tightness of the chain should be checked. When the chain is too tight and pedaling is laborious, if it is too loose, it is easy to vibrate and rub against other components. The sag of the chain is 1-2mm, which is more suitable. Generally, it can be adjusted appropriately when riding without pedals. When adjusting the chain, first loosen the rear wheel nuts, evenly screw in and out the left and right chain adjustment screws, adjust the chain tightness, and then retighten the rear wheel nuts.
4. Before using an electric bicycle, the lubrication of the chain should be checked. Feel and observe whether the chain shaft rotates flexibly and whether the chain links are severely rusted. If there is rust or inflexibility in rotation, an appropriate amount of lubricating oil should be added, and in severe cases, the chain should be replaced.
