Cybex Gazelle S Review

At $1,349.90 total-to-double, the Gazelle S is a premium investment — but it covers significantly more ground than a fixed double. The 20+ configurations mean one stroller adapts to an infant plus toddler, two toddlers, or even a baby plus preschooler with the Kid Board. The Kid Board's 44-lb capacity is unique in the market — no competitor offers a ride-along board for a child this heavy. If you have a 2–3+ year age gap or foresee needing three riding positions, the Gazelle S is one of the few strollers that genuinely handles all scenarios. For families who simply need two equal seats, the Mockingbird 3.0 at $724 covers similar ground at nearly half the cost.

The Gazelle S gate-checks free on all major US carriers — Delta, United, American, Southwest, and JetBlue. At 26.9 lbs in single configuration (estimated 34–35 lbs in double), it's well under any carrier's stroller weight limit. The 25.4" width navigates jet bridges more easily than wider doubles. For flying, remove the second seat and travel in single configuration to reduce weight and bulk. Gate check at the jet bridge and request return at the aircraft door. The Gazelle S is too large for overhead bin storage on any commercial aircraft.

Cybex Aton, Aton 2, Cloud Q, and related Cybex infant car seats mount natively to the Gazelle S frame without adapters — they use the same click-in system. For other brands, Cybex sells dedicated adapters for Maxi-Cosi Mico, Nuna PIPA series, and UPPAbaby Mesa series. Cybex notes that "no additional adapters are needed" for the second seat unit itself — the second seat attaches directly to the Gazelle S frame mounting points. Confirm current compatibility at cybex-online.com before purchasing, as adapter compatibility is updated with each new car seat model year.

With the main seat, second seat, and Kid Board all installed, the Gazelle S technically supports three children simultaneously: one in the main seat (up to 50 lbs), one in the second seat (up to 50 lbs), and one standing or sitting on the Kid Board (up to 44 lbs). This is a unique capability — no other convertible double offers a third riding position for a child this heavy. The Kid Board ($149.95) folds up when not in use and doesn't interfere with the stroller's fold. This configuration is particularly effective for a 3–4 year age gap where the oldest child still tires out on longer outings.

The Gazelle S is one of the best convertible doubles for urban environments specifically because of its 25.4" width — 4–5" narrower than comparable side-by-side doubles. Urban parents can navigate standard apartment doors, café entrances, and elevator doors in double configuration without stress. All-wheel suspension handles urban terrain including cracked sidewalks, cobblestones, and curb cuts. The one-hand self-standing fold is fast enough for transit situations where quick collapse is needed. In a survey of convertible double strollers for urban use, the Gazelle S's width and fold mechanism consistently rank among the top choices (Extra Petite, 2024).

The total cost to double with the Cybex Gazelle S is $1,349.90, broken down as: Gazelle S stroller unit $999.95 + Gazelle S Seat Unit $349.95. No additional adapters are required between the two Gazelle S seats — the second seat attaches directly to the frame. If you add the Kid Board for a third child, the total rises to $1,499.85 ($999.95 + $349.95 + $149.95). If you need a bassinet carrycot for newborn use, the Gazelle S Cot is sold separately at approximately $199.95, bringing the newborn-ready double to approximately $1,549.85 without the Kid Board.
