Christmas STEM toys for 5-year-old boy

Christmas STEM toys for a 5-year-old boy spark his curiosity indoors — a bicycle sparks his whole body outdoors. A 16 inch pedal bike is just the right size for a five-year-old, with a low frame, a simple coaster brake and training wheels that keep him steady as he learns to pedal and steer. As his balance sharpens, the training wheels lift off, so one thoughtful gift carries him from wobbly first rides to confident solo cruising. Along the way he builds leg strength, coordination and the kind of independence STEM kits cannot quite deliver, plus plenty of fresh-air, screen-free fun. Tie a bow on the handlebars and let him roll into Christmas morning with a grin. Explore these five-year-old boys' bikes and give a gift that moves.
