The Quick Verdict
Get the Bag Boy Quad Pro. It lists at $49.05 less than the Blade Trio, comes with the umbrella holder and drink holder already in the box, and it has four wheels to the Blade Trio's three. The Blade Trio is worth the extra $49.05 if your trunk is tight — it folds to 8.2 inches deep, and that flat profile is genuinely different from what the Quad Pro offers. Check price at TGW →
What They Have in Common
Both are push carts with a two-year warranty and a storage console. The Quad Pro lists maintenance-free tires; the Blade Trio lists detachable wheels and a height-adjustable handle. Neither maker mentions a seat.
Where They Differ
Trunk fit
This is where the Blade Trio makes its case. It folds flat — 27.9 × 23.2 × 8.2 inches. That 8.2-inch depth is the number to measure in your hatchback or SUV before you buy. The Quad Pro folds to 24 × 17 × 15 inches. By volume the Blade Trio is slightly smaller (3.1 cubic feet vs 3.5), but the Quad Pro's longest folded dimension is 24 inches versus 27.9 on the Blade Trio. What that means in practice: the Quad Pro is a more compact brick; the Blade Trio is a longer, wider, thinner slab. Whether one works better in your specific trunk depends entirely on what else is in there and how high your cargo floor sits — measure the 8.2 inches first.
Wheels and braking
The Quad Pro runs four wheels. The Blade Trio runs three, and Big Max publishes that the front wheel does not swivel. The Blade Trio brakes with a single foot brake; the Quad Pro uses a handle-mounted parking brake. One's set by foot, the other from the handle.
Weight
The Blade Trio is 14.77 lbs, 1.23 lbs lighter than the Quad Pro's 16 lbs. That's the kind of gap you'd notice lifting both carts side by side at the tailgate, though you probably wouldn't notice it mid-round.
What's in the box
The Quad Pro includes a detachable umbrella holder, a drink-and-phone holder, a magnetic accessory plate, and a deep scorecard console. The Bag Boy Top-Lok system handles bag attachment. The Blade Trio includes a magnetic storage cover and an adjustable storage net — but Big Max shows beverage and umbrella holders as add-ons, not included. If you want them on the Blade Trio, that's a separate purchase.
Price and warranty
The Quad Pro lists at $299.95; the Blade Trio at $349. The Blade Trio's warranty starts at two years and extends to five if you register online. The Quad Pro is two years, no extension mentioned.
Who Should Buy Which
Get the Bag Boy Quad Pro if:
- You want a fully equipped cart out of the box — umbrella holder, drink holder, and bag attachment all included without a follow-up order.
- You prefer a handle-mounted parking brake to a foot brake.
- $299.95 is the right price point and the $49.05 gap matters to you.
- Your trunk fits a 24-inch long cart without trouble.
Get the Big Max Blade Trio if:
- Your cargo space is height-constrained and 8.2 inches of depth is what makes a push cart fit — measure before you buy.
- You're willing to add drink and umbrella holders separately in exchange for that flat profile.
- A five-year warranty with registration matters to you and you're confident you'll register it.
- 1.23 lbs of weight savings at the tailgate is worth $49 more at list to you.
The Bottom Line
The Blade Trio's flat fold is a real thing — 8.2 inches deep is a legitimately different shape from anything that folds to a 15-inch minimum. If that flat profile solves an actual problem in your car, the $49.05 premium makes sense. For everyone else, the Quad Pro comes in lower, arrives equipped, and does the same basic job. The Top-Lok bag attachment and the included accessory kit mean you're not hunting for add-ons after the fact.
