Keenz and Wonderfold are two of the most popular stroller wagon brands offering push-style, box-shaped wagons for multiple children. Both brands offer a breadth of features and accessories not consistently found in the more stroller-like wagons like the Graco Adventure and Evenflo Xplore.

To gather first-hand information and experience with popular stroller wagons, we purchased and tested 11 different versions from a variety of brands. This included the Keenz 7S 2-Seater, the Wonderfold W4 Elite 4-Seater, and the Wonderfold W1 Original 2-Seater.

Keenz 7S Video Review
Common Complaints vs Our Experience: Keenz 7S
Some owners of the Keenz 7S have complained about the stroller wagon’s maneuverability difficulties and how the wheels sometimes fall off while in use. Yikes! We wanted to find out if we would have the same experiences, so we did some comparisons.
Below is only a handful of these comparisons but you can view our FULL criticism and experience table here: Keenz 7S Stroller Wagon Review.
Criticism | Our Experience |
---|---|
Pushing and steering are difficult | It’s easier to push and steer than the Wonderfold wagons but not as easy compared to smaller stroller wagons (e.g. Evenflo Pivot Xplore). |
Wheels tend to fall off | We didn’t have any issues with this when in use but we did notice the wheel release button can accidentally get pushed when the wagon is being folded up |
Too bulky when folded up | We agree. It’s not as bulky as the Wonderfold W4 but it’s much bulkier than the Wonderfold W1. |
Difficult for a child to get in with canopy on | Yes, there’s not much room between the walls of the stroller and the canopy, making it hard to place a child in without pushing against the top. |
Too bumpy of a ride | Bumps feel worse when legs cannot be placed in a footwell, which is the case for the Keenz 7S. |
Wonderfold W4 Elite Video Review
Common Complaints vs Our Experience: Wonderfold W4 Elite
We reviewed all the critical customer reviews of the Wonderfold W4 and compared them with our own experience to help you sort out the good from the bad.
View our ENTIRE criticism and experience table here: Wonderfold W4 Elite Stroller Wagon Review.
Criticism | Our Experience |
---|---|
Brake or axel get bumped when pushing | Many of our testers of various heights did report having their feet bump the brake bar or sometimes the axel bar when pushing the W4 Elite. |
Push bar is fixed height | Although some Wonderfolds have been sold with non-adjustable push bars the W4 Elite has an adjustable handle. |
Customer service slow to respond | We received a fast and courteous response from customer service. |
Big and hard to lift | The 4-passenger wagons of the W series are heavy (50+ lbs) and bulky to lift and maneuver when folded. The W1 Original, W2 and X2 models are lighter. |
Pulls to the side when pushing | We didn’t experience much veering to the side when testing the Wonderfolds |
How We Researched and Tested
We performed 65 tests and used the wagons over the course of a spring, summer, fall season, scoring them in these categories:
- Parent Comfort and Usability
- Steering and Maneuverability
- Kid Comfort and Usability
- Folding and Transport
- Part and Material Quality
We were assisted by several moms and dads and their kids who used the wagons for walking, hiking and events.
Parent Comfort and Usability
We compared customer service, assembly, storage, cleaning and brakes to score the wagons in parent comfort and usability.

Unboxing and Assembling
Wonderfold W1 Original | |
Keenz 7S | |
Wonderfold W4 Elite |
Keenz took 1 hr 40 minutes and Wonderfold 1 hr 2 minutes to provide a human response to our customer service emails. Both are excellent results.
The more accessories a wagon has, the longer it takes to get set up the first time.
Parent Cupholders
The Wonderfold wagons, including the W4 Luxe do not come with parent cupholders. They are sold separately but this is a big miss.
The Keenz 7S has a single adjustable cup holder that mounts to the frame, and a pocket that can be used for a cup holder on the back of the wagon.

Handles
The Keenz 7S has both a pull and push handle. They are vegan leather and adjust to 10 different placements ranging from 28″ to 42.5″.

The Wonderfolds have a single, adjustable handle in the back made from foam rubber handles. They are protected with a zippered fabric cover.
Pull handles can be purchased separately for the Wonderfold wagons.

Car Seat Adapters
Neither of these brands currently sell car seat adapters for their wagons. Here are some car seat adapter hacks for the Wonderfold.
Storage
Both Keenz and Wonderfold W series wagons arrive with excellent storage capacity. The W1 Original has almost none.

Storage ratings:
Keenz 7S | |
Wonderfold W4 Elite | |
Wonderfold W1 Original |
The W4 Elite has a wide and deep basket that stretches across the back. The W1 Original has only a thin zippered compartment.

Our full review of the Wonderfold W1 Original
In addition to the rear storage basket, the W4 has storage compartments in the front and also pockets that hang from each side of the wagon.

The zippered entrance at the back of the W4 Elite can be used to store bulky items underneath the seats. Kids love to be able to crawl in themselves.

Cleaning Rating
Keenz 7S | |
Wonderfold W1 Original | |
Wonderfold W4 Elite |
The fabric on both of these wagons is thick and we were able to clean mud off with a wet rag.
There are inner seams in both wagons that can trap some crumbs. The insides of the Keenz are easy to access the insides. Wonderfolds, with the seats installed, are more difficult, but the opening in the back helps.
Brake Effectiveness
To test how quickly the brakes would stop the wagons we loaded them up, let them roll down a hill, and attempted to stop them with only the brake pedals.

The Keenz brake pedal was easy to access and engage. The Keenz did stop but stuttered and skidded for a few feet before stopping.
The Keenz brake was easy both to set and disengage, even with bare feet.
The Wonderfold brake pedal is also easy to reach from the pushing position. It engages easily but is hard on sandalled feet to release.
The Wonderfold also did some skidding before it stopped in the runaway wagon test.

Steering and Maneuverability
We loaded the wagons up with 80 lbs of dog food and pushed them on all kinds of terrain to assess steering and maneuverability. Steering and Maneuverability Scores:
Keenz 7S | |
Wonderfold W1 Original | |
Wonderfold W4 Elite |
It’s important to note that the 4-passenger quad Wonderfold W4 in the graph above is being compared with the 2-passenger Keenz 7S and 2-passenger W1 Original. The 4-passenger Keenz 7S+is heavier than the 7S and also 7 inches wider. It would likely have a lower maneuverability score than the 2-passenger version.
Pushing and Turning
We found the Keenz to take considerably less force to turn from a dead stop than either of the Wonderfold wagons.
Force to turn each wagon 90-degrees from a stop.
Keenz 7S | |
Wonderfold W1 Original | |
Wonderfold W4 Elite |
The force to get each of these wagons rolling straight forward was remarkably similar.
Maneuverability is definitely impacted by the weight of the wagons:

Terrain Performance

We pushed the wagons over rough terrain, bumps and obstacles to assign a Bump rating:
Wonderfold W4 Elite | |
Wonderfold W1 Original | |
Keenz 7S |
Grass: The Keenz did a little better on grass than the W4 and about the same as the W1.
Hills: Hills are something you want to avoid with the W4 Elite. The Keenz and W1 were comparatively much easier to push on hills though still didn’t perform as well as the Veer, Anthem or Evenflo.
Sand: None of these wagons do well on soft sand.
Wheel Sizes
Larger wheels make it easier to roll over obstacles and smooth out the ride.
I expected that the Wonderfold W4 Elite would have the biggest wheels given that it is the heaviest wagon we tested. It has among the smallest rear and front wheel diameters.
The rear wheel diameter of the W4 Luxe is 11.5 inches, which is 2 inches more than the Elite but still smaller than the Keenz and many other wagons.
The Keenz wheels are sized more appropriately and more comparable to other wagons.
Rear-wheel diameter:

Front-wheels:
The Wonderfold W4 Elite front wheels are 8″ in diameter and 1.9″ in width. The W4 Luxe has 9.5″ diameter front wheels.
Keenz 7S from wheels are a smallish 7 inches in diameter.
Both brands have steel springs incorporated in the wheel mounts.
Folding and Transport
In this category the streamlined W1 Original performed well but both the Keenz and W4 are comparatively difficult to fold and stow.
Folding and transport scores:

Folding Time
Wonderfold W4 Elite | |
Keenz 7S | |
Wonderfold W1 Original |
Sun shades are important features of wagons but add time to the folding process for both the Keenz and Wonderfold.

The Keenz has strap to clip on the bottom that is part of the recommended unfolding process.

Folded Size in Cubic Feet
Keenz 7S | |
Wonderfold W1 Original | |
Wonderfold W4 Elite |
The Keenz 7S has a reasonably small folded size at 8.9 cu ft and the W4 Elite Quad is much larger.


In the Trunk of a Car or Back of a Minivan
The W1 Original fits fine in the back of our Honda Civic. The Keenz 7S did not fit in the Civic and we didn’t even try the W4 Elite.

All the stroller wagons fit fine in the back of our minivan even with the rear seats of the vehicle in the upright position.

Kid Comfort and Usability
In this category we evaluated how well each wagon addresses things that affect children like the comfort of the seats and harnesses, being able to get in and out of the wagon, canopy coverage and more. Scores in Kid comfort and usability:
Wonderfold W4 Elite | |
Wonderfold W1 Original | |
Keenz 7S |
Seat Comfort
The Wonderfold Elite and Luxe models include seats that raise children off the floor of the wagon. The recline can be adjusted by selecting where to hang them on the frame.
The lifted seats provide a footwell which does not exist for the Keenz 7S Original and W1 Original wagons. In those wagons, kids sit with their backs against the end of the wagon and their feet stretched out in front.

Like the Keenz, kids sit on the floor in the W1 Original.

Seat comfort ratings:
Wonderfold W4 Elite | |
Keenz 7S | |
Wonderfold W1 Original |
Harness Comfort
Both the Keenz 7S and Wonderfold harnesses are padded. Harness comfort ratings:
Wonderfold W4 Elite | |
Keenz 7S | |
Wonderfold W1 Original |
We found the W1 harness to be challenging to buckle.
Snack Tray
The Wonderfold Original and Elite models do not come with a snack tray. Neither does the Keenz 7S.
The Keenz XC series and Wonderfold Luxes do have a fabric snack tray that stretches across the center.
Inner Wagon Space
Keenz 7S | |
Wonderfold W1 Original | |
Wonderfold W4 Elite |
The W4 Elite is a quad stroller but is only 21″ across on the inside. The new Keenz quad wagons are 33″ across.
The Keenz 7S is an inch or so shorter in each direction than the W4 Elite.
An advantage of not having hanging seats is that kids can use the inner surface of the wagon as a play area. It also makes a passable nap station, like a pack n’ play on wheels.
Getting In and Out
The Wonderfold has high sides to accommodate the seats but the “back door” lets kids climb in and out by themselves.

The Keenz 7S canopy posts are not very high. Some parents complain that it is difficult to slide kids in over the side and under the canopy. Others say the canopy blocks their view of children while pushing.

Canopy
The fabric canopy on Wonderfold wagons slides from side to side to block the sun. The Keenz 7S canopy features drop-down sun shades. The Keenz also has see-thru mesh netting that drops down from each end.
The top of the Keenz 7S canopy can be zipped back to allow for more airflow.

Although neither of these canopies provides 100% full sun coverage, they are adequate for most situations.
Part and Material Quality
TPart and material quality scores:
Keenz 7S | |
Wonderfold W4 Elite | |
Wonderfold W1 Original |
Keenz 7S Part Quality
The Keenz 7S is solidly built.
The important moving parts including the handles, folding mechanism, wheels and brakes operate smoothly and feel robust.
The Keenz has quite a few zippers, velcro, snaps and buckle clips. We haven’t had any problems with it operationally.
Wonderfold Part Quality
The Wonderfolds are made of high-quality, durable materials.
Some of the design elements like small wheels and positioning of the brake pedal where your feet bump into it while walking are undesirable. But we don’t have any concerns with the longevity of the wagon and haven’t experienced any quality problems.
