Compact folding
Three seconds. Try it.
One motion folds the whole trike into a single piece small enough for a hall cupboard, a car boot or an overhead locker. No parts come off, nothing to lose.
Open and ready.Press and hold the button. Let go early and it stays open.
Patented 360° easy steer
One hand. Any direction. Even backwards.
Steering a trike from behind used to mean wrestling it. A light movement of the parent handle turns the front wheel, so you can push, turn and carry a coffee at once.
- 360Turns on the spotCafe tables, supermarket aisles, the narrow bit of the footpath.
- RReverses without liftingThe only stroller trike that rolls backwards smoothly through a turn.
- 1One hand, alwaysBecause the other one is holding a coffee, a dog lead or a bigger sibling.
The Wonder™ range
Three Wonders. Same fold, same steering, same safety.
Where they differ is how early your child can start, and how comfortable the ride stays over a long day.
Wonder™
The lightestThe lightest way in, and the one that actually leaves the house. Carry-on approved.

Not sure which one?
Find your smarTrike in 30 seconds.
Three questions. The answer changes completely depending on whether your child can sit up on their own yet, so we start there.
01How old is your child?
02How often will you use it?
03What matters most?
Your match appears here
Answer the three questions and we will point you to one trike, and say why.
See itLife with Wonder™
Out the door, up the stairs, into the locker.
The same trike on the school run, at the cafe, on the plane and in the park. Drag to look around.
Stroller-trike vs pram
A pram carries them. This teaches them to ride.
That difference matters most between one and three, the window where toddlers want to move on their own but tire quickly and cannot yet pedal a bike.
With a Wonder™
Parent-pushed on the walk out, child-powered on the way home, folded into the boot when they have had enough.
- ✓Stroller for the walk out, trike for the walk home
- ✓Certified to stroller safety standards
- ✓Under 7 kg and carry-on approved
- ✓Grows through four modes without buying again
With a pram and a separate trike
Two things to store, two things to carry, and a trike that sits in the garage until they can pedal.
- –Pram outgrown around the time they want to ride
- –Most toddler trikes are toy-certified, not stroller-certified
- –Full-size prams rarely go in the cabin
- –Three purchases across the same three years

After the Wonder™ · 12 months to 12 years
Nothing gets outgrown. It just changes shape.
The Xtend range picks up where the Wonder leaves off. A seated ride-on a one year old pushes with their feet, then a three-wheel scooter, then a two-wheel scooter for big kids.

Got this for my 18 month old and he is so obsessed. Love that he can grow into it as well.

Easy to assemble. The walking handle and safety seat make it so much more enjoyable to take my one year old grandson out.
Theresa E. · Verified buyer

See the rangeQuestions parents ask
Before you buy
The full FAQ covers ages, weights, folding, airline travel, safety, delivery and warranty.
Read every answerWhat age is a smarTrike stroller-trike for?
Wonder max™ from 6 months, Wonder™ and Wonder+™ from 10 months, all to around 3 years. Under 10 months the seat needs to recline, and only the Wonder max™ does.
Is the Wonder approved as carry-on luggage?
Yes. Every Wonder™ folds to a single compact piece designed to go in the overhead locker. Check your airline's cabin allowance before you fly, as limits vary by carrier and fare.
Is a stroller-trike as safe as a pram?
The Wonder™ range is tested and certified to stroller safety standards rather than toy standards, with a 5-point harness, a shock-absorbing front wheel and a one-foot rear brake.
Can I steer it with one hand?
Yes. The patented 360° steering system turns the front wheel from the parent handle, on the spot and in reverse, with one hand.
What warranty do I get in Australia?
Two years on every smarTrike sold in Australia, on top of your rights under Australian Consumer Law. Claims are handled by our Melbourne team.
