This stroller-to-suitcase invention turned down every Shark Tank offer and still won big

Is it a stroller or is it a suitcase?

That’s the question you might be asking when you first see the TernX Carry-On Luggage Stroller.

This one-of-a-kind design is the only carry-on bag that transforms into a fully certified stroller. It fits in the overhead bin, so there’s no need to check it at the gate and it folds without having to unpack anything. In other words, it’s the ultimate solution for parents who don’t want to scramble at the airport.

The idea came from Tack and Hoe Ping, the husband-and-wife team who founded TernX. As parents, they knew firsthand how complicated and stressful traveling with young children could be, so they wanted to create a stroller that could carry their own luggage, as well as their little ones’ essentials, without slowing them down.

That’s how TernX was born.

Of course, the Pings also knew they weren’t alone. Millions of families face the same challenge — wanting to travel with their children without the hassle. Bringing the TernX Stroller from concept to reality took years of research, design, testing and refining before it was finally ready to bring to the market.

When the Pings eventually appeared on Shark Tank, they received two offers, and still decided to walk away. The founders later explained that they chose to remain 100% independent because building the product they envisioned required the freedom to stay true to their original mission.

That decision seems to be paying off.

Since appearing on Shark Tank, the TernX Carry-On Luggage Stroller has earned plenty of recognition, including a TIME Magazine Best Invention award, seven international design awards and most recently, the Red Dot: Best of the Best 2026 award, one of the highest honors in the global design industry.

It’s not just the innovative concept that makes the TernX Stroller stand out for traveling families; it’s the thoughtful details built into every part of the design.

With 18 pounds of storage capacity, the TernX provides plenty of room for everything parents want to keep within reach, from diapers and wipes to snacks, toys, and everyday essentials. Of course, there is still plenty of room for parents’ essentials, too.

The stroller also transforms in seconds — simply by pressing the aerospace-grade aluminum frame and extending the handlebar to switch from carry-on luggage to a fully functional stroller.

Despite the fact that it turns into a suitcase, TernX still has little ones’ comfort top of mind. An adjustable backrest and reclining seat help keep kiddos comfortable throughout their travels, while the oversized UPF 50+ canopy provides protection from the sun.

Thousands of parents have praised the TernX as a true “game changer” and “lifesaver,” with some calling it the best travel stroller they have ever used. For families navigating airports and everyday adventures, it offers a simple solution designed to make parenting a little bit easier.
