Gazelle S 2 Stroller

by Cybex · Babesta Pick — Best Inline Single-to-Double for Older and Mixed-Age Kids

The Cybex Gazelle S by Cybex is a modular stroller that starts as a single and converts to a double inline — one child behind the other — with over 20 configurations of seats, cots, and infant car seats. At 50 lbs per seat, it carries more weight than any comparable inline double in its category, which is the detail that makes it the right answer for families with older kids, bigger kids, or a meaningful age gap between two children. It’s birth-ready with the Gazelle S Cot or a Cybex infant car seat (both sold separately), and the seat unit takes over from 3 months through approximately age 4.

What sets the Gazelle S apart from other modular strollers is the combination of carrying capacity and practicality. The 55 lb total basket (lower basket plus detachable shopper) is the largest in its class. The one-pull harness secures one child in seconds — or two, which anyone who has strapped two kids into a double stroller on a schedule will appreciate. It folds compact with one or two seats attached, which matters when you’re trying to fit a double stroller into a NYC apartment entryway. For families planning ahead or already navigating two kids at different stages, this is the stroller built for the long game.

Specifications

Best For/Not For

Best For

•      Families with mixed-age kids — especially where one child is older or heavier and needs the full 50 lb per seat capacity

•      Parents expecting a second child who want one stroller that grows from single to double without buying a new frame

•      Families with two older or bigger toddlers where per-seat weight limit is the deciding factor

•      NYC families who need a double that folds compact enough to store at home or fit in a car trunk

•      Parents who want 20+ configuration options — cot, car seat, or seat in practically any combination

•      Families who carry a lot — 55 lbs of total basket capacity is the largest in this class

Not Ideal For

•      Families who want a side-by-side double — the Gazelle S is inline only; for side-by-side, the Bugaboo Donkey 6 is the better fit

•      Tight NYC sidewalks and curb cuts where the longer inline length adds extra maneuvering — worth knowing before you buy

•      Families who primarily need a lightweight travel or subway stroller — at 28.4 lbs this is a full-size stroller

•      Jogging or rough off-road terrain

Is It Suitable for My Baby’s Age?

Newborn (0–3 months)

Yes, with the right accessory. The seat unit is suitable from 3 months, but the Gazelle S Cot (sold separately) provides a lie-flat bassinet option from birth. Alternatively, a Cybex infant car seat with the included adapters works as a newborn configuration for the travel system setup. Ask the Babesta team which newborn option best suits your plans.

Infant (3–12 months)

Yes — from 3 months the Gazelle S seat unit is ready to use. The reclining backrest adjusts to provide ergonomic support, the XXL UPF 50+ canopy with mesh ventilation keeps younger babies comfortable, and the one-pull harness makes securing a wriggling infant genuinely faster.

Toddler (1–4 years)

Yes — the 50 lb per seat weight limit carries comfortably through the full toddler phase and beyond. In double mode, both seats support up to 50 lbs each, which means the Gazelle S remains a viable double stroller for older children long after comparable doubles have been outgrown.

Is It Good for NYC / City Use?

For a full-size modular double, the Gazelle S handles city life well. The compact fold — 32.9″ × 25.4″ × 12.2″ with seats attached — fits in most car trunks and can be stored in a city apartment without completely taking over the entryway. The advanced suspension and adjustable handlebar make daily sidewalk use comfortable for both parent and child.

The honest trade-off for NYC use is length. As an inline double, the Gazelle S is longer than the UPPAbaby Vista, which makes navigating tight curb cuts and crowded sidewalks slightly more demanding. It’s manageable — plenty of NYC families run inline doubles every day — but worth knowing before you commit. Compared to the Bugaboo Donkey 6, which is side-by-side and wider rather than longer, the Gazelle S is the better choice when per-seat weight capacity matters most and you have older or bigger kids. If you want a side-by-side double and weight limits are less of a concern, the Donkey 6 is the call. If you have mixed-age kids and need both seats to carry a real-sized child, the Gazelle S wins.

Why Babesta Carries It

We carry both the Gazelle S and the Bugaboo Donkey 6 because they answer different questions. The Donkey 6 is our recommendation for families who know they want a side-by-side double from day one. The Vista is great for twins or mixed age who are closer in age, and the Gazelle S is our recommendation for families where one or both kids are older, bigger, or where the age gap means the per-seat weight limit will genuinely matter for years. At 50 lbs per seat — higher than comparable inline doubles — the Gazelle S doesn’t get outgrown on the weight side before families are ready to move on from a double altogether.

The 20+ configuration system is also genuinely useful rather than just a marketing number. The ability to mix a cot, a car seat, and a toddler seat on the same frame means the Gazelle S can handle twins in different configurations, a newborn and a toddler, or two older children — all on one frame, without buying a new stroller at each stage. For families who are planning ahead or who already have two kids at very different ages, this is the stroller that keeps up.

Frequently Asked Questions

Can I use this as a single stroller and convert to a double later?

Yes — that’s exactly what the Gazelle S is designed for. It starts as a fully capable single and converts to an inline double with the addition of a second seat unit (sold separately). The frame, fold, and basket all work in both configurations without modification.

What do I need to use it as a double?

A second Gazelle S seat unit, sold separately. The frame, adapters, and basket are all included — you just add the second seat when you’re ready. Ask the Babesta team and we’ll walk you through the full double configuration before you buy.

Is it side-by-side or inline?

Inline — one child sits behind the other. If you want a side-by-side double, the Bugaboo Donkey 6 is the better fit. If you have older or bigger kids and per-seat weight capacity is the priority, the Gazelle S is the stronger choice.

Can I use it from birth?

Yes, with the Gazelle S Cot (sold separately) for a lie-flat bassinet setup, or with a compatible Cybex infant car seat and the included adapters. The seat unit itself is suitable from 3 months.

What is the weight limit per seat?

50 lbs per seat, in both single and double mode. This is higher than most comparable inline doubles, which is the key reason the Gazelle S is our recommendation for families with older or bigger children.

How does it compare to the Bugaboo Donkey 6?

They solve different problems. The Donkey 6 is side-by-side and is our pick for families who want a traditional double where both children sit next to each other. The Gazelle S is inline and is our pick when per-seat weight capacity matters — older kids, bigger kids, or a significant age gap. Come into Babesta and we’ll help you work out which one is right for your family.

Does it fit in a NYC apartment?

The fold — 32.9″ × 25.4″ × 12.2″ with seats attached — is compact for a double stroller and fits in most car trunks and apartment storage spaces. It’s a full-size stroller, so measure your entryway, but it’s designed with city storage in mind.

Is it suitable for jogging?

No — the Gazelle S is a city and everyday stroller, not a jogging stroller. Ask the Babesta team about dedicated jogging options.

Can I try it in person?

Yes — come see us at Babesta Tribeca, 56 Warren Street. Our team can demonstrate both single and double configurations, show you the fold, and roll it on the pavement outside so you can feel the ride and the handling for yourself.

Can I add this to my baby registry?

Yes — the Gazelle S is a strong registry choice for families who are planning ahead for a second child or already navigating two kids at different ages. A Babesta registry comes with exclusive perks and services, and our team can help you figure out exactly which configuration and accessories to register for
