What matters for small children (ages 3–5)

For small children, bike size is determined by wheel diameter — not frame size. At this age, the priority is confidence and safety over performance. Your child should be able to touch the ground flat-footed when seated at the lowest saddle position. A bike that's too large is dangerous — children cannot control bikes they can't reach the ground from. Consider starting with a balance bike (no pedals) for children under 4, as this teaches balance and steering before adding pedal complexity. For pedal bikes, look for models with coaster brakes (backpedal to stop), which are easier for small hands than hand brakes. Bike weight matters enormously at this age — a bike that weighs more than 30% of the child's body weight will be hard to control. Expect to replace the bike every 1–2 years as your child grows.

Tires sizing guidance

Every bike tire carries two size numbers on the sidewall: the modern ETRTO (ISO 5775) format like 28-622 — width in millimetres, then bead-seat diameter — and an older Imperial label like 700×28c, 26×2.10, or 20×4.0. The first number stays the same regardless of width (700c = 622 mm, 26" MTB = 559 mm, 27.5" = 584 mm, 29"/700c = 622 mm). Width affects everything: a 700×25c rolls fast on smooth roads, 700×32–35c is the modern endurance and gravel default, 2.1–2.4" suits trail MTB, and fat-bike tires run 4.0–4.8" wide for sand and snow. Kids bikes follow wheel diameter — 12", 14", 16", 18", 20", and 24" — and replacement tires must match exactly. Always check your rim's max width and your frame/fork clearance (typically printed on the chainstay or fork) before going wider.

Expert tips

Measure your child's inseam (floor to crotch) standing against a wall — this is more important than height for sizing
At the lowest saddle position, your child should be able to plant both feet flat on the ground
A lighter bike is always better — aim for under 30% of your child's body weight
Balance bikes are the fastest path to riding proficiency — most balance bike kids skip training wheels entirely
