The Quick Verdict
Get the Bag Boy Quad Pro. It lists at $60 less than the Nitron Swivel and comes in 2.5 lbs lighter. The Nitron Swivel is worth the premium if you want a 360° swivel front wheel that locks and a one-step auto-open that uses a Nitro-Piston to unfold itself. For everyone else, the Quad Pro does the job for less money. Check price at TGW →
What They Have in Common
Both are Bag Boy push carts with Top-Lok bag attachment, a detachable umbrella holder, a cup holder, a deep storage console, and a 2-year limited warranty. Neither lists a seat. Same brand either way — you're choosing between two different designs.
Where They Differ
Weight and folded size
The Quad Pro is lighter at 16 lbs; the Nitron Swivel is 18.5 lbs. That 2.5-lb gap is modest on the fairway but real when you're hoisting it into the trunk twice a round.
The folded sizes tell an interesting story. By volume, the Nitron Swivel folds smaller — 3.1 cubic feet vs. 3.5 — but the numbers worth checking are the individual dimensions. The Nitron Swivel folds to 18.7 × 13 × 22 in. The Quad Pro folds to 24 × 17 × 15 in. The Quad Pro is lower — 15 in high against 22 — but it's wider and longer, with a 24-in longest dimension against the Nitron Swivel's 22 in. Which one fits your trunk depends on your car: if you've got vertical clearance and limited floor space, the Nitron Swivel's taller-but-narrower profile may suit you better. If the hatch is wide but shallow, the Quad Pro's flat shape works in your favor.
Wheels and brakes
The Nitron Swivel has three wheels, with a 360° swiveling front wheel that can be locked. The Quad Pro has four wheels. The Quad Pro's parking brake is mounted on the handle. The Nitron Swivel uses a dual rear brake system that locks both back wheels. They just work differently.
Opening mechanism and accessories
The Nitron Swivel describes its fold as auto-open using a Nitro-Piston, one step. The Quad Pro uses a two-step open and fold.
On accessories, both come with a detachable umbrella holder and an accessory bag included; the Nitron Swivel adds integrated umbrella storage. The Quad Pro also includes a magnetic accessory plate; the Nitron Swivel includes two magnetic plates. Both have a drink holder and a console.
Price
The Quad Pro lists at $299.95. The Nitron Swivel lists at $359.95. That's a $60 gap at list.
Who Should Buy Which
Get the Bag Boy Quad Pro if:
- You want the lower list price and the lighter carry
- Your trunk is short on height — the Quad Pro folds 15 in high against the Nitron Swivel's 22
- You prefer a handle-mounted parking brake
- You'd rather have four wheels under the bag than three
Get the Bag Boy Nitron Swivel if:
- You specifically want a 360° swivel front wheel with a lock
- The auto-open, one-step fold matters to your routine
- Your trunk has more height than floor space, and the Nitron Swivel's folded shape fits better
- You're happy to pay $60 more for those features
The Bottom Line
The Quad Pro lists for less and weighs less. The Nitron Swivel's case rests on the swivel front wheel and the one-step piston open — real features, but $60 worth of real depends on whether you'll actually use them. For most walkers, those aren't make-or-break.
