To use the Aeffect R pedals, just step on them firmly when you're riding your trail or down - country bike. When stepping on, make sure your feet are centered on the platform for the best balance. As for maintenance, it's a good idea to clean the pedals regularly. You can use a soft brush and some mild soap to remove dirt and grime. Also, check the pedals for any signs of wear and tear often. If you notice any loose parts, get them tightened up right away. Avoid riding through extremely muddy or wet conditions for long periods as this might reduce the pedals' lifespan. With proper care, these pedals will serve you well on your single - track rides.
