Joystar Bike Size Chart

Joystar is Joy Kie’s kids-bike brand (sister line to HILAND), sold for toddlers through youth. The bikes are wheel-size based, not adult centimeters. This page is Joystar’s kids wheel chart. Check inseam, saddle height, and whether the child can reach the brake levers; training-wheel models still need standover clearance. Size by wheel diameter rather than copying an adult S/M/L from another brand.

How to measure

Height filters the chart. Cycling inseam decides which overlapping size to keep. The method is the same for every brand.

Height and inseam

Height

Take shoes off and stand tall, looking straight ahead. A helper should rest a flat object on the crown of your head, then run a tape from the floor to the underside of that object. Save the number in inches and centimeters — charts use both.

Inseam

Stand tall and barefoot with feet slightly apart. Ask a helper to measure vertically from your crotch to the floor. Keep your legs straight and feet flat.
