Junior Bikes

Childrens bikes are traditionally measured by wheel size in inches. The sizes are a guide as to what wheel size would be suitable for a particular age group.

Wheel Size Recommended Age
12" 2 - 4 years
14" 4 - 6 years
16" 5 - 8 years
18" 6 - 9 years
20" 8 - 11 years
24" 9 - 12 years
26" Adult

N.B. All BMX bikes come with a 20" wheel and a frame size from 10" to 12" (frames do vary depending on the manufacturer). BMX bikes are suitable for ages from 8 years to mid teens.

Adult Bikes

Adult bikes are measured by the size of the frame (measured in inches from the center of the bottom bracket to the top of the seat tube). The sizes below are a guide as to which frame size would be suitable for the riders height.

Height Measurement Frame Size
5' to 5'4" 17"
5'4" to 5'8" 18"
5'8" to 6' 20"
6' 22"
