Kuidas valida BMX jalgratta suurus?

Teile ideaalselt sobiva BMX-ratta või raami valimisel on palju olulisi asju, kuid üks asi, mida peaksite alati arvestama, on raami ülemise toru (top tube) pikkus. Allpool toome välja tähtsamad mõõdud:

0,9–1,1m pikkune sõitja peaks valima 14-tolliste rataste läbimõõduga jalgratta
1,1–1,2m pikkune sõitja peaks valima 16-tolliste rataste läbimõõduga jalgratta
1,2–1,4m pikkune sõitja peaks valima 18-tolliste rataste läbimõõduga jalgratta
1,4–1,6m pikkune sõitja peaks otsima jalgratast, mille rattad on 20 tolli ja raami ülemise toru pikkus on kuni 20,5 tolli
1,6–1,8m pikk sõitja peaks otsima jalgratast, millel on 20 tolli rattad ja raami ülemise toru pikkus umbes 20,5 – 20,75 tolli
1,8 ja + pikkune sõitja peaks otsima jalgratast, mille rattad on 20 tolli ja raami ülemise toru pikkus vähemalt 21,0 tolli
