Picked up one of those Rangers for nearly free, when Twelve (now Fifteen) decided he wanted to learn to ride a "real" two -wheeler when he outgrew his adaptive bike..
For a $250 retail (until recently) bike for a teen/ tween to toss around the neighborhood it does the job.
"Universal 26 MTB" tough enough to take some abuse and V-brake 3x7 is . pretty easy to keep working happily. Also fairly simple/ standard enough for teaching said teen/tweens about how to look after their own bikes.
Also inexpensive enough that you don't have to worry so much about it on the bike rack when they want to ride it to class.

I had a Murray BAJA when I was his age. That bike should never have been built.
