WTB 2 Mtn bikes for kids 5'-2"

[Supermoto]

Looking for 2 Mtn bikes for my nephews. They are about 5'-2" so a small would probably be best. Something name brand, not walmart. Doesn't have to have great component but needs to work well. I'm trying to get them into mtn biking so I need a bike that they won't get frustrated with. Currently they are riding POS from the dump. Looking to spend $100 each

Let me know what you have

Thanks

Splurge a little and buy them a Yeti to share. I know someone who has one for sale.
