3.2 About the lubrication of parts
Lubrication part: chains, flywheels, and headsets require regular maintenance.
Our suggestion is to drip a little lubricating oil (such as L-AN46GB443) on the position of the chain and the

You can buy lubricating oil for bicycles and add it yourself, or you can add lubricating oil at a nearby bicycle
shop. This is the most convenient method.
3.3 About chain
The best tightness of the chain: use your fingers to push/pick the position of the lower middle of the chain, the
chain can move up and down 10-15 mm.
The tightness of the chain will directly affect the performance of the Shimano transmission.
3.4 Brake pads
1. The wear of the brake pads in the front and rear brakes should be checked every month. If you find that the
brake pads are severely worn, please replace the brake pads in time to avoid affecting the braking effect of the
