The 26” bike frame has been a great for our 8 year old (Around 4’4”). I purchased it after seeing the 27.5” Trek was really just too big and heavy for him on the trails. Fortunately, like many people, I had a box of old 26” sized bike parts that could be used, and found a few more parts and got it together. It’s not built super light at the minute, but it’s a MUCH better bike for our 8 year old on the trails and he was much more able to go out and ride for an hour or more on the trails with me. Probably lost 8-10 lbs. It’s built with a 27.5” sized fork, some older 8 speed drivetrain parts (to be upgraded at Christmas), 26” wheels and 2.3” Conti tires (I know the tires are backwards… I’ll fix it later, along w/ the steerer length, etc). It’s a little snug to drop out the rear wheel from the frame when removing it unless you back off the axle nut quite a bit more than “just loose” to clear the rear derailleur and the frame to pull the wheel out. Not a big deal, and may be fine with another rear der. You can run either a front derallier or an external dropper post with the internal routing. The routing pops out at the bottom bracket, so you’d need a cable housing stop for a cable actuated dropper. I’ve done this on another carbon frame.
