Using these pedals is easy. First, adjust the spring tension according to your preference. When getting on the bike, align your shoe cleat with the larger entry target on the pedal and gently step down to clip in. When you want to get off, just twist your foot out. As for maintenance, regularly clean the pedals to remove dirt and debris. Check the spring tension from time to time to make sure it's still at your desired level. If you notice any unusual noises or a decrease in performance, it might be time to have them checked by a professional. And always remember to be careful when walking with the cleats on hard surfaces to avoid excessive wear.
