    are 20 in bmx bikes universal?

    hi, im a fairly new member to bmxing, and new to this forum. i jsut got a newer bmx bike yesterday, that was 20 inch because my old one was about to crack in half, and i was wondering something. after a day of doing some bunny hops, and some flatland, i realsized then when not standing on the pedals, and sitting, the bike was small. are all bmx bikes size 20 universal? like, is that what most people use even if there taller than me? im 5.7-5.8 . thanks.

    That chart seems more for racing than anything else - a 21.5" toptube for someone that's 5'10" is way too long for anything but.

    You'd probably be fine on a frame with a 20.75"-21" toptube - it all really depends on how your bars are setup and how far back you've got your rear wheel, really.

    I'd say anything between 20" and 21" would be fine. Then again it's whatever you like
