Official sizing guide for 2026
CUBSALA is an Amazon-direct BMX specialist. The lineup tiers riders by skill - Beginner (Echo, Freestyle), Intermediate (Yaphet), Expert (Syzygy), Race (Trident) - and by age (12"/14"/16"/18"/20"/24" wheels). All sizing is done by rider height and age range; no published frame stack/reach, so size by wheel diameter and the age window in each listing.

|---|---|---|
| 12" Wheel (ages 1-4) | 2'10" - 3'5"(86 - 105 cm) | 13.8" - 18.5"(35 - 47 cm) |
| 14" Wheel (ages 3-5) | 3'1" - 3'9"(94 - 115 cm) | 15.7" - 20.9"(40 - 53 cm) |
| 16" Wheel (ages 4-7) | 3'7" - 4'2"(109 - 127 cm) | 18.9" - 23.6"(48 - 60 cm) |
| 18" Wheel (ages 5-9) | 3'9" - 4'8"(114 - 142 cm) | 20.9" - 26.8"(53 - 68 cm) |
| 20" Wheel (ages 7-adult) | 4'2" - 6'2"(127 - 188 cm) | 23.6" - 35.4"(60 - 90 cm) |

Specific sizing recommendations for CUBSALA's most popular bike models. Geometry measurements shown for reference size (typically M or 54cm).

24" beginner BMX with high-tensile steel frame, rear U-brake, and 4 stunt pegs included. Fits riders 4'10"-6'0" - large enough for teens and most adults but lighter and more flickable than a 26" mountain bike. Ships 85% pre-assembled.

Kids freestyle BMX in 18" (ages 5-9, height 3'9"-4'8") and 20" (ages 7-13, height 4'2"-5'2") wheel sizes. Steel frame, rear U-brake, 4 stunt pegs, and a 360° rotating handlebar on some trims. Pick the 18" for first-time freestyle riders, the 20" once they've outgrown a 16" pedal bike.

Intermediate 20" freestyle BMX with hi-ten steel frame, sealed bearings, and 4 stunt pegs. Fits teens and adults 4'10"-6'2" who have outgrown a beginner 20" but aren't ready to spend on a chromoly competition frame. Multiple color options.
