Hi all,

I'm in the market for a 20" street/ramp/dirt bmx bike for a ten yr old kid who is 4' 9" tall. He's got an 18" DK and is past due for a 20" bike. Size charts are showing him as a junior w/ roughly 17" - 19" TT length... seems a lot of the race bikes run graduated frame sizes but I don't see many street bike frames running graduated sizes. Was thinking of getting a Kink curb or launch but will it be too big? Any recommendations would be appreciated!

My son's nearly 10 and on an 18", I reckon he'll get another couple of years out of it. Bmx's are supposed to be small and going from an 18 to a 20 is a pretty big size difference.
Maybe try some slightly taller bars and slightly longer cranks. Maybe a longer stem too.
My plan is to get some parts for my son's 18" that will get him some more time on it, but also work well on a 20", like 160mm cranks, 8" bars etc
