Bike Size for 5 Year Old — Sizing Guide & Chart 2026

Five-year-olds are typically ready for a 16" wheel bike, though smaller children (under 107 cm) may still fit a 14" bike better. At this age, the majority of children have the coordination to ride without training wheels, and many can begin using hand brakes alongside or instead of a coaster brake. The correct fit means your child can sit on the saddle and touch the ground with the balls of their feet — flat-footed contact is no longer necessary. Look for bikes with a simple single-speed drivetrain; gears are unnecessary and add weight and complexity. A quality 16" bike typically weighs 6–8 kg; avoid anything over 9 kg, as heavier bikes are a serious barrier to enjoyment and skill progression.
