To use these pedals, simply step on them and start pedaling. They're designed to give you a good grip without pins, so you can ride comfortably. When riding, make sure your feet are centered on the pedals for better control. As for maintenance, regularly clean the pedals with a mild soap and water to keep them in good condition. Check for any signs of wear and tear, like loose parts or excessive friction. If you notice any issues, it's best to get them fixed right away. Also, store the pedals in a dry place when not in use to prevent rusting.
