Frequently asked questions

Yes, it arrives fully preassembled. Simply unbox, unfold, and you're ready to roll.

The luggage shell is crafted from recycled German polycarbonate. The stroller frame is made from aerospace aluminum.

Product weight: 17 lbs (7.8 kg), excluding sun canopy.

22" x 14" x 9" (55cm x 35.5cm x 23cm) — designed to meet IATA carry-on standards for most major airlines. Carry-on size and weight restrictions vary by airline and are subject to change without notice; it's the traveler's responsibility to verify current limits with their airline prior to travel.

18 L (4.8 gal), plus a convenient under-seat basket with a 4.5 lbs (2 kg) capacity.

Yes, the compartment is easily accessible in both luggage (folded) and stroller (unfolded) mode.

It functions as a 2-wheeled suitcase. This design allows the wheels to be recessed for a better overhead bin fit. Attempting to roll the luggage while it is standing upright or on its stopper stand side can put undue stress on the stand and may cause permanent damage.

Yes, the handle adjusts to three settings: 105 cm, 114 cm, and 123 cm.

Fully extend first: press the release button and pull the handle all the way up. Adjust downward: press the button again to lower it into your desired position (Short, Medium, or Tall). You'll hear a firm click when it's locked in place.

Please note the left and right side of the telescopic handle are not designed to move in parallel. A small amount of play or wobble in the handle is an intentional engineering requirement for smooth sliding.

No, you don't have to unpack the luggage. The integrated luggage and our “loaded fold” system is designed not to interfere with the folding/unfolding mechanism.

No, we're not a one-second fold stroller. Our focus is on safety, stability, and convenience — while our unfolding might take seconds instead of “one second,” it's all for good reason. We're offering a one-of-a-kind solution that combines the best of both worlds: a suitcase and stroller in one.

From 6 months (around the age when the child can hold their head up independently) up to a 4-year-old toddler, depending on size and weight.

The TernX Carry On Luggage Stroller is certified to international standards for a child weighing up to 48.5 lbs (22 kg).

Yes, it's equipped with an adjustable 5-point safety harness.

The seat reclines into two positions (99° and 126°). The backrest height is also adjustable, extending from 15" (38cm) to 20" (50cm).

Yes, the stroller is equipped with a fixed footrest.

The canopy can be stored inside the luggage compartment when not in use. It also comes with its own storage bag that can be attached to the handle.

Thanks to its independent front wheel suspension and smart design, it handles various surfaces well. That said, due to their compact size, the wheels of a travel stroller will never be as big or as smooth as a standard stroller's on uneven surfaces.

Yes. The TernX Carry On is rigorously tested and holds major international safety certifications for a weight capacity of up to 48.5 lbs (22 kg): United States (ASTM F833-21), Europe (EN1888-2:2018+A1:2022), Australia & New Zealand (AS 2088:2022+A1:2024 and AS/NZS 2088:2013), Canada (SOR/2023-101), and South Korea (KC Safety Confirmation).

The TernX needs to be inverted (flipped) so it can be tilted and pulled behind you at an angle using the telescopic handle — it's not designed to be rolled vertically like a four-wheeled “spinner” suitcase. Attempting to roll the luggage while it is standing upright or on its integrated stand can put undue stress on the components. Damage resulting from upright rolling is considered misuse and is not covered under our warranty.

The transition is simple and takes seconds. Check out our conversion video for a walkthrough.

The stroller frame and seat are permanently integrated for safety. However, the soft goods (textiles) are removable for cleaning — please follow the care label instructions for best results.

Yes — the Sun Canopy and Luggage Stroller Cover are both available in our Accessories collection.

Unfortunately, the stroller is not compatible with car seats.

This model is designed for a single child and is not currently rated for twin or double use.

While the TernX is the ultimate travel companion, it is also engineered for daily use. With its aerospace aluminum frame and independent suspension, it's built to handle city sidewalks, shopping trips, and daily commutes just as well as airport terminals.

Yes! It's designed to fit in standard airline overhead bins and complies with IATA carry-on size requirements. Carry-on size and weight restrictions vary by airline and are subject to change without notice — it's the traveler's responsibility to verify current limits with their airline prior to travel.

Most airlines will classify the TernX as a stroller due to its design and functionality (it’s a certified stroller). Please note, you may need to fold it at the aircraft door or check it at the gate if space is limited — each airline has its own requirements, so it's best to check with your specific airline before traveling.

The TernX Carry On folds down to 22" x 14" x 9" (55cm x 35.5cm x 23cm), well within standard carry-on limits for 90+ airlines. We'd still recommend double-checking your specific airline's carry-on policy before you fly, since sizing rules can vary or change.

Strollers are typically considered “special items” and often don't count toward your carry-on luggage. The TernX is designed to fit carry-on dimensions, helping you avoid gate-checking. We'd still recommend double-checking your specific airline's carry-on policy before you fly, since rules can vary or change.

TernX Carry On Luggage Stroller is airline friendly and designed to meet carry-on size guidelines set by IATA, TSA, and FAA. No universal “approved” certification exists from these authorities for strollers as standalone consumer products — “approved” here means the stroller meets common airline carry-on dimensions, not a formal certification by a governing body.

The TernX travel stroller is designed to meet standard carry-on size requirements and is compact enough to fit down the aisle on most airlines. Airline regulations can vary, so we always recommend checking with your carrier prior to travel.

We highly recommend taking it as a carry-on. The TernX was specifically engineered for the cabin, so it stays with you. Checking it into cargo exposes it to rough baggage handling, which can cause cosmetic or structural damage not covered by our warranty.

The TernX Carry On comes with a 24-month limited warranty from the date of purchase (12 months for Indonesia). This covers manufacturing defects. See our full Warranty Policy for details.

Our warranty covers manufacturing defects in materials and workmanship. It does not cover normal wear and tear (e.g., fading fabric, worn wheels), damage from misuse or improper maintenance, accidental damage (dropping, liquid spills), or damage caused by airlines or third-party carriers (claim directly with the carrier for transport damage).

The serial number is located on a black sticker on the frame tube, underneath the seat or basket — or on the original box if you still have it.

Not quite the same thing. A manufacturing defect (discovered during normal use) is handled under warranty. If your item arrived visibly damaged in transit, let us know right away with photos so we can look into it separately — this is handled differently than a standard warranty claim.

If purchased via an authorized retailer, please contact the retailer directly to submit the claim first. If purchased via ternx.com, you can visit our return portal or email hello@ternx.com with your order details, a description of the issue, and a photo or short video of the defect.

For products purchased directly through ternx.com: return shipping costs for inspection are at your own expense. If your claim is verified and covered under warranty, TernX covers the cost of shipping the repaired or replacement product back to you.

No. The warranty period does not reset if your unit is repaired or replaced — any replacement or service is covered for the remaining duration of your original warranty, calculated from your initial purchase date.

No, the TernX warranty is non-transferable. It applies exclusively to the original purchaser and is valid only when the product is purchased directly from our website or an authorized retailer. Proof of purchase is required for any claim.

Keep the luggage and frame clean and dry — dry promptly with a microfiber cloth if it gets wet, and clean off debris as soon as possible. Use a damp microfiber cloth with warm water on the frame (mild soap for a deeper clean), and let it air out fully before storing. Slight oil marks on the telescopic handle are normal manufacturing lubricant residue. Hand wash soft goods and hang to dry per the care label; prolonged sun exposure may cause fading. Regularly check and clean the wheels, and apply silicone spray lubricant to the brake pedal to keep it operating smoothly.

Yes, we currently offer replacements for high-wear parts like wheels, and the canopy. A list of spare parts and accessories can be found on ternx.com. Alternatively, please contact hello@ternx.com for current availability and pricing.

There may be a short break-in period, like all high-precision gear. Practice the fold/unfold a few times indoors. If it feels unusually tight, ensure the luggage compartment isn't overstuffed and no fabric from the seat or harness is caught in the folding joints. Always fully retract the telescopic handle before folding.

Yes. The handle is designed with a small amount of play or tolerance so it can slide smoothly and won't jam from dust or temperature-based expansion. This does not compromise structural integrity.

If you've been traveling through dusty, sandy, or muddy environments, debris may have entered the brake housing. Clear the area with compressed air or a damp cloth and apply a small amount of silicone spray lubricant. Avoid heavy oils like WD-40, which attract more dirt.

This is usually caused by a buildup of hair, lint, or fine grit in the wheel axel. Wipe the axels clean, ensure no debris is wrapped around the wheel pins, and apply a quick spray of silicone lubricant to the swivel joint.

Ensure the two shoulder straps are correctly aligned with the waist tabs before inserting them into the center buckle. If it feels gritty, rinse the buckle under warm running water and air-dry it to restore smooth clicking.
