1.After riding a bicycle for a period of time, all parts shall be checked and adjusted to prevent parts from loosening and falling off. An appropriate amount of oil shall be injected into the sliding part regularly to maintain its lubrication
2. After the vehicle is wet or damp by rain, the electroplated parts shall be dried and wiped in time, and then coated with a layer of neutral oil (such as domestic sewing oil) to prevent rust
3. The parts coated with varnish shall not be wiped with oil, so as not to damage the paint film and make it lose luster
