Bmx 20.5 or 20.75?

Question

Whats the difference between a 20.5 then a 20.75 bmx bike? im 14 and i am about 5'5 and i weigh 120? would a 20.5 or 20.75 bmx be better for me?

Answer 1

that is the lengh of the top tube called the tubetop. usually the taller you are the bigger tubetop youre gonna want cuz it will be more comfortable.  20.75 is big for being 5'5. an especially if this is your first bike its better and easier to start off riding on a smaller bike.  i would say deffinitly get the 20.5 and if some friends have a 20.75 incher try it out different people like to ride different sizes depending on whats more comfortable for them.

Answer 2

A 1/4" really doesn't matter at all.

Answer 3

Well if ur really good then top tube should be as long as possible so you have more clearence for tricks but again its all person prefs
