Should beginners start with clipless or flat pedals?

Most coaches recommend starting mountain biking with flat pedals to develop fundamental bike handling skills—weight distribution, cornering technique, and the ability to quickly dab a foot. Once these basics are solid (typically 3-6 months of regular riding), transitioning to clipless adds efficiency and security. Starting clipless too early can create dependency and slow skill development. There's no shame in riding flats, and many expert riders still prefer them for certain disciplines.
