Zoe Twin V2 vs Mockingbird Single-to-Double 3.0
A side-by-side against a tandem, $529 against $549. The Zoe Twin V2 is 23 lb, folds to 11.5 x 30 x 28 inches, and takes 60 lb per seat, with add-on seats for a triple or quad. Owners say it clears ordinary doorways despite its width. The Mockingbird starts as a single at 28 lb, adds a second seat with the $175 kit, and weighs 36 lb with both seats on. It folds to 18 x 26 x 34, with a one-hand fold that stands, and a 25 lb basket against the Zoe's 10. The Mockingbird takes 50 lb per child, and its $50 adapter covers ten infant seat models; Zoe's page names no compatible seats and its adapters are extra. So the Mockingbird is the better fit for one child now and another later, and the Zoe suits twins or two toddlers who both need a seat today and must pass through a door. Count the $175 and $50 extras before comparing sticker prices.
Folded, the Zoe Twin V2 makes a 5.59 cu ft box to the Mockingbird Single-to-Double 3.0's 9.21 cu ft. Neither fits a 22 x 14 x 9 in carry-on sizer: the Zoe Twin V2 misses by 14 in and the Mockingbird Single-to-Double 3.0 by 12 in. The Zoe Twin V2 is 5 lb lighter by its maker's figure (23 lb to 28 lb).
