Using these pedals is easy. Just install them on your bike following the standard procedure. When riding, make sure your feet are centered on the concave platform for the best stability. For better grip, you can adjust the 10 pins on each side according to your needs. There's no limit to the rider's weight, so anyone can use them. When it comes to maintenance, use the grease port to add grease regularly to keep the bearings working smoothly. Keep the pedals clean after rides to prevent dirt from getting into the bearings. The pedals come with a 5 - year warranty, so if you encounter any problems, you can reach out for support.
