Using the CRS BMX Bike is straightforward. Just hop on, pedal, and start enjoying your ride across various terrains. When riding, make sure to wear proper safety gear like a helmet and knee pads. For maintenance, regularly check the brakes to ensure they are working well. Clean the chain and apply lubricant every few rides to keep it running smoothly. Also, check the tire pressure before each ride; the recommended tire size is 2.35'. If you notice any loose parts, tighten them immediately. And don't forget to store your bike in a dry place to prevent rusting.
