My cousin is 12yrs old, 6th grade, 4'7" and 82lbs. I'm trying to determinie if he should ride a 20" or24" bike?What is a good brand (gt, haro, mongoose, giant, schwinn, dk, free agent, mosh, redline)? I doubt he will race the bmx bike and most of his riding will be on trails with his friends. Any advice/suggestions?

20"

24"

20" for tricks, but if he's just going to be tooling around might as well get him a more comfortable 24" bike.

20"

24"


at 4'7" you think he should ride a 24"?

20" is good.
