Using your Sunday EX - Julian Arteaga Signature BMX bike is a breeze. Just hop on, hold the handlebars firmly, and start pedaling. You can use the removable braking hardware whenever you need to stop. When riding, make sure to wear proper safety gear like a helmet and knee pads.
For maintenance, regularly check the tires to ensure they are properly inflated. You can use a standard bike pump to do this. The chain should be lubricated every few rides to keep it running smoothly. Use a good quality bike chain lubricant and apply it evenly along the chain.
Keep an eye on the headset and hubs. If you notice any unusual noises or looseness, it might be time to have them tightened or serviced. When not in use, store your bike in a dry place to prevent rust and damage.
