20” Wheel Bikes
Buying guide
20" wheel bikes, explained.
20" is where bikes get interesting: first gears (usually 6–7 speed), first proper mountain-bike styling, and the size where kids start riding real distances. Suits roughly ages 5 to 8 (115–135cm).
Gears at this size should be simple — a single shifter, no front derailleur — and the bike should stay under 10kg if the budget possibly allows.
Sizing
First gears: look for a simple single twist or trigger shifter. Weight under 10kg makes hills possible.
Who it suits
20" wheels typically suit ages 5–8 — but height beats age every time. When in doubt, measure.
