Babyzen YOYO3 Review

The Babyzen YOYO3 is worth $500–$550 specifically for families who fly frequently and want the most compact, widely recognized premium travel fold. Its 7.1" fold depth is the thinnest in its class, and folded it is small enough to lie flat in the overhead bin on most full-size jets. For families who fly fewer than 6 times per year, the Joolz Aer+ ($449–$499) offers better expert scores (84 vs 76/100), a 10-year warranty, and an easier fold at a lower price. The YOYO3's value is its travel capability, brand recognition, and the exclusive YOYO Connect double conversion, not its daily-driver features like basket size or fold ease. Retired from manufacturer: Babyzen no longer sells the YOYO3, but it may still be available for purchase on third-party websites or secondhand. Its replacement is the Stokke YOYO5.

Yes, in most cases. In the US, a collapsible stroller is a free extra item, not your carry-on bag. American and Frontier allow it in the cabin if it fits in the overhead bin, and Delta doesn't count it toward your bag allowance. Babyzen lists the folded YOYO at 52 x 44 x 18 cm (20.5 x 17.3 x 7.1 in) and says most airlines accept it as cabin luggage, while noting that rules vary by airline. Folded, this stroller is small enough to lie flat in the overhead bin on most full-size jets. Bin space varies by plane, smaller regional jets often can't take it, and the crew has the final say, so have a gate-check bag ready. Some international airlines are stricter: Qantas and Lufthansa count a stroller as part of your carry-on with tighter size limits, and KLM brings it into the cabin only if space allows. Check before you fly. Ryanair and Wizz Air use a 40 cm cabin-bag width limit and the YOYO is 44 cm wide, so plan to gate-check on those carriers. Gate-check is free on US airlines, and strollers come back at the jet bridge. See Velivolo's overhead bin size guide.

The Babyzen YOYO3 is compatible with Nuna PIPA series, Cybex Aton and Cloud series, Maxi-Cosi Mico series, Clek Liing, and BeSafe iZi Go Modular via brand-specific adapters (~$80). The adapter system creates a travel system from birth, bypassing the 6-month minimum age. Confirm current compatibility on babyzen's website or stokke.com, as the list updates with new car seat models. Without a car seat, use the separately purchased 0+ Newborn Pack ($140) for infants from birth to 6 months.

The Babyzen YOYO3 and YOYO2 share the same 20.5×17.3×7.1" fold dimensions and approximately 13.6 lb weight — the physical fold mechanism was not redesigned between generations. The YOYO3 carries updated branding under Stokke's ownership and any minor fabric and component refinements made since the acquisition. Both sell simultaneously through mid-2026 during the brand transition. The YOYO2 typically sells at a slight discount as stock clears. If YOYO2 is $40+ cheaper and new, the performance difference is negligible — buy the YOYO2.

The Babyzen YOYO3 seat is for children aged 6 months and older. For newborn use, Babyzen offers the separately sold 0+ Newborn Pack ($140) — a padded recline insert that supports a newborn's head and body in the YOYO3 frame. Alternatively, the YOYO Bassinet ($399) provides a lie-flat sleep surface suitable for newborns. Compatible infant car seats (Nuna PIPA, Cybex Aton) also enable use from birth without the pack. The 0+ Newborn Pack is the most economical newborn solution at $140 vs. the $399 bassinet.

The YOYO Connect ($499, sold separately) attaches to the YOYO3 frame to create a two-seat side-by-side configuration. Both seats can be positioned forward-facing or one can face the parent. Babyzen lists the folded Connect setup at 52 x 44 x 24 cm (20.5 x 17.3 x 9.5 in): remarkably compact for a double, though at 9.5 in thick it is bulkier than the single YOYO3, so be ready to gate-check it. Each seat supports children from 6 months to 48.5 lbs. The connection mechanism is tool-free and takes approximately 2 minutes to attach.
