Keenz vs Wonderfold Stroller Wagon Comparison

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.

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.

CriticismOur Experience
Pushing and steering are difficultIt’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 offWe 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 upWe 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 onYes, 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 rideBumps 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.

CriticismOur Experience
Brake or axel get bumped when pushingMany 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 heightAlthough some Wonderfolds have been sold with non-adjustable push bars the W4 Elite has an adjustable handle.
Customer service slow to respondWe received a fast and courteous response from customer service.
Big and hard to liftThe 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 pushingWe 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.

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 Wonderfold handle is slightly higher than the Keenz 7S.

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.

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 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.

break pedals of the keenz and wonderfold
Rear brake pedals of the Keenz and Wonderfold

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:

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.

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.

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.

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.

Kid Comfort and Usability

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.

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.

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.

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.
