I'm assuming the yellow one is some kind of cheap knockoff as it has a kickstand plate and a place for a crank guard. No labeling on it whatsoever.

The blue GT has a 'made in USA' sticker by the rear wheel, GT stamped at the rear hub and "CR-MO 4130" above the crank.

It belongs to my nephew who has passed and I'm looking to restore them for his mother. Need years and models to order parts. Appreciate it.

    Blue one looks like a 99 vertigo and yellow looks to be a early 2000s similar model

    Blue one is for sure a Vertigo, best guess is 97 because in 98 they started using the GT Piston stem

    Blue one looks like as said, early 2000s late 90s gt performer or vertigo. Other looks like a newer Gt or maybe an older mid 90s 2000s Dyno.

    Gt performer and a mongoose. Gt is built in USA gt towards the end. And mongoose is a Walmart special from early 2000
