If you’ve spent any time in the baby gear rabbit hole, you’ve probably landed on Doona’s website twice: once for the car seat that folds into a stroller, and once for the Liki Trike that somehow turns into four different vehicles as your toddler grows. Both are from the same brand, both promise to replace a pile of other gear, and both are genuinely expensive enough that you want to get the decision right the first time.
So here’s the question that actually matters: are these two products solving the same problem twice, or are they built for two completely different phases of your child’s life? Short answer, they’re not competitors. Long answer, below, because the “do I need both” decision depends a lot on your specific baby, your car situation, and how you actually move through your day.
Quick answer: The Doona Car Seat Stroller is a certified infant car seat that becomes a stroller, built for roughly birth to 12–18 months. The Liki Trike is a ride-on toddler trike that isn’t a car seat at all, built for 10 months to 3 years. They overlap for a short window in the middle, but they’re doing different jobs. Most families end up wanting the Doona first and the Liki Trike second, not both at once.
What the Doona Car Seat Stroller Actually Is
The Doona is, at its core, one seat shell doing two mechanical jobs. Underneath the fabric, the shell has a set of wheels tucked into its base. In car seat mode, those wheels are folded flush against the frame and the shell clicks into a LATCH base or gets belted in like any rear-facing infant seat. When you’re ready to walk, you press a release handle on the back of the seat, the wheels swing down and lock into place, and the whole thing becomes a lightweight stroller in a matter of seconds, no separate stroller frame required.
That single-shell design is the entire point of the product. You’re not transferring a sleeping baby between two pieces of gear, and you’re not hauling a stroller frame and a car seat as two separate objects through a parking lot. The current lineup includes the Doona+ (around $650) and the newer Doona X (around $850, released in 2026), which adds a taller handlebar, a no-rethread harness, and additional recline positions. Either version is certified as an actual car seat, meeting FMVSS crash standards in the US, which is the detail that matters most: this is safety equipment first and a stroller second.
The tradeoff is that it’s built around infant proportions. Doona rates the seat for children from about 4 to 35 pounds and up to 32 inches tall, which in practice tends to land somewhere between 12 and 18 months, though smaller babies stretch that timeline out further. Once your child outgrows the height or weight limit, the Doona’s job is finished, regardless of what “mode” it’s in.
What the Doona Liki Trike Actually Is
The Liki Trike works on a completely different mechanism. It isn’t a shell that transforms itself; it’s a fixed frame with modular components that get added or removed as your child develops. The “stages” aren’t really modes so much as a sequence of hardware changes: you start with everything attached (backrest, control bar, footrest, armrest, canopy) and progressively strip parts away as your toddler gains the strength and coordination to need less support.
| Stage | Age Range | What’s Attached |
|---|---|---|
| Parent Mode | 10–18 months | Backrest, parent control bar, footrest, armrest, canopy |
| Push Mode | 18–24 months | Backrest, parent control bar, footrest |
| Tricycle Mode | 24–30 months | Backrest, parent control bar, pedals |
| Bike Mode | 30–36 months | Lower backrest, pedals only |
A clutch system connects the parent-facing control bar to the steering and pedals, which is the clever part: you can steer and pedal for your toddler in the early stages, then gradually hand that control over as they’re ready, rather than switching to an entirely new product. The trike itself weighs under 15 pounds, folds down small enough for a car trunk or an overhead bin, and is rated for a maximum load of 37.5 pounds. Doona sells it in a few tiers, with the base S3 model priced around $280. It is not a car seat, has no crash certification, and isn’t designed to go anywhere near a moving vehicle.

The Real Difference: They’re Not Actually Competing
It’s easy to see two products from the same brand and assume you’re choosing between them, the way you’d choose between two stroller brands. But the Doona and the Liki Trike aren’t aimed at the same job. The Doona exists because newborns and small infants need to be in a certified car seat every time they’re in a vehicle, and building the stroller into that same seat removes a transfer step during the hardest, most sleep-deprived stretch of early parenting. The Liki Trike exists for the stage after that, once your child is upright, curious, and wants some version of independence on a walk, but is still too young to control a real bike or scooter.
Where the confusion usually comes from is the age overlap. Doona rates its seat up to around 12–18 months depending on your child’s size, and the Liki Trike’s earliest stage starts at 10 months. That gives you a real window, roughly 10 to 15 months, where a child could technically use either one. But “could” isn’t “should”: inside a car, only the Doona is legally and functionally appropriate. Outside the car, on a sidewalk or at the park, the Liki Trike gives an almost-walking toddler something the Doona was never designed for, which is a sense of steering and motion they control.

So, Do You Need Both?
It depends less on the products and more on where your child is right now, and what your day-to-day actually looks like.
You have a newborn or young infant
Start with the Doona and stop there for now. The Liki Trike is wasted money at this stage since your baby isn’t sitting up or walking yet, and the earliest Liki stage still expects 10 months of neck and trunk strength. Revisit the trike once your child is approaching their first birthday.
You have a toddler and already own an everyday car seat
If you’re past the infant stage and already have a convertible car seat installed in your vehicle, the Doona isn’t adding much for you anymore. The Liki Trike, on the other hand, is a strong standalone buy for walks, park trips, and travel, and it can do that job on its own for close to two years.
You want one continuous system from birth through preschool
This is the scenario where owning both genuinely makes sense, not because they overlap, but because they hand off to each other. You use the Doona for the newborn-to-toddler stretch, retire it once your child outgrows the height or weight limit, and bring in the Liki Trike right around the same time. Buying both isn’t redundant here, it’s sequencing two products that were built to cover consecutive stages rather than the same one.
You travel often, with a baby or a toddler
For infant travel, the Doona is the standout, since it’s airline-approved and removes the need to pack a separate stroller or check a bulky car seat. For toddler travel, the Liki Trike folds down small enough to fit in a trunk or overhead bin, and gives a toddler who’s done sitting in a stroller somewhere to direct their energy. Frequent travelers are actually the group most likely to get full value out of owning both, just at different points on the calendar.
Bottom line: Don’t buy both at the same time expecting them to compete for the same 10-to-15-month window. Buy the Doona when you’re expecting or have a newborn, and add the Liki Trike closer to your child’s first birthday, once the Doona is aging out anyway. Bought this way, the two products barely overlap in cost or in use, they just pass the baton.
A Few Ways to Save If You’re Buying Both
- Stagger the purchases. Buy the Doona around your due date and hold off on the Liki Trike until closer to the first birthday, so you’re not paying for gear that’s sitting unused.
- Watch for bundle and seasonal pricing. Doona periodically bundles the car seat with accessories like the LATCH base, and the Liki Trike goes on sale around major holidays and back-to-school periods.
- Consider the resale market. Doona car seats and Liki Trikes both hold value reasonably well secondhand, since babies age out of the Doona quickly and toddlers age out of the trike’s earliest stage just as fast, leaving plenty of lightly used units in circulation. Just confirm the Doona has no crash history before buying a used one.
- Skip the trike if you already have a scooter or balance bike on the way. The Liki Trike earns its keep mainly in that 10-to-24-month window before a toddler can manage a balance bike; if you’re planning to jump straight to one, you may not need the full four-stage system.
Frequently Asked Questions
No. The Liki Trike has no crash certification and isn’t designed for vehicle use at all. It’s strictly a ride-on and stroller-alternative for use on foot, on sidewalks, at parks, or indoors.
There’s no hard switch date, but most families find the transition happens naturally somewhere between 12 and 18 months, whenever their child reaches the Doona’s height or weight limit. Since the Liki Trike’s earliest stage starts at 10 months, it’s reasonable to bring it in slightly before the Doona is fully retired.
It depends on how your toddler uses a stroller. If they’re increasingly resistant to sitting still, the Liki Trike’s ability to shift from parent-controlled to toddler-pedaled use tends to solve a problem a standard stroller can’t. If your toddler is still happy in a regular stroller, there’s less urgency to add it.
The Doona+ is the original, more affordable version at around $650. The Doona X, released in 2026 at around $850, adds extra recline positions, a taller handlebar, and a no-rethread harness. Either one covers the same core function; the X is aimed at parents who want the newest comfort features and are willing to pay for them.
At the end of the day, the “vs.” in the title is a bit misleading. These two products were never meant to fight for the same slot in your gear closet, they’re meant to hand off to each other as your baby becomes a toddler. Buy for the stage you’re actually in, and let the next stage wait until you’re closer to it.
