The Quick Verdict
Get the Sun Mountain PX4. At $330 list — $31 more than the Alphard — you get a cart that weighs 5.8 lbs less, comes with dual umbrella holders and a valuables pouch in the box, and carries a three-year frame warranty. The Alphard Cybercart Push+ is worth a look if you want a path to a powered cart later: Alphard sells a Motor Upgrade Kit that converts it into a remote-controlled caddy, and no equivalent upgrade exists for the PX4.

What They Have in Common
Both include a cup holder, a storage console and an umbrella holder, and both hold the bag with bungees: adjustable-length cords on the PX4, a strap for the bottom of the bag on the Alphard. Both list under $350.
Where They Differ
Weight and portability
The PX4 weighs 17.2 lbs. The Alphard weighs 23 lbs. That 5.8-lb gap is noticeable when you're lifting either cart in or out of the trunk twice a round — the kind of thing you don't notice on the third hole but remember at the end of October when you've done it fifty times. Five-plus pounds is also real if you're traveling with the cart.
The Alphard folds to 20 × 15.5 × 22 inches — 3.9 cubic feet — and Alphard says the longest dimension is 22 inches. Sun Mountain doesn't publish folded dimensions for the PX4, so there's no volume comparison to make. If trunk space is a real constraint, you'd want to measure against the Alphard's published dims; the PX4 is an unknown quantity on that front.
What's in the box
Both come with a drink holder, storage console and umbrella holder. The PX4 goes further: dual umbrella holders, a mesh basket and a valuables pouch are all included. The Alphard adds a sand-bottle holder and dual magnetic accessory mounts — a different set of extras, not a lesser one. The Alphard also includes a scorecard holder and storage net; the PX4 has a mesh basket that covers similar ground.
The seat is a different story. The Alphard lists it as an optional accessory, not included. Sun Mountain doesn't say either way on the PX4.
Brake and wheel configuration
The Alphard has dual rear brakes. Sun Mountain's copy for the PX4 doesn't describe a brake. Whether that's a genuine absence or an omission from their product page, the Alphard is the only one of the two with a published braking system. The PX4 has four wheels with extendable front axles; Alphard doesn't print a wheel count for the Push+, only a swivel front wheel.
The upgrade path
This is where the Alphard separates itself from the PX4. Alphard sells a Motor Upgrade Kit that converts the Cybercart Push+ into a remote-controlled electric caddy. If you think you might want that option in a year or two, paying $299 now — and $31 less than the PX4 — for a cart that can be motorized later is a real argument. Note that Alphard is explicit: this kit is not the Club Booster V2Pro, and the Push+ is not compatible with that one.
Warranty
The PX4 carries a three-year frame warranty with a one-year term on other parts. The Alphard covers everything under a two-year warranty.
Who Should Buy Which
Get the Sun Mountain PX4 if:
- You want the lightest cart here — 17.2 lbs makes a difference over a season of trunk-loading.
- You want dual umbrella holders and a valuables pouch without a separate order.
- A three-year frame warranty matters to you and the Alphard's two-year term doesn't cut it.
- You want a four-wheel cart.
Get the Alphard Cybercart Push+ if:
- You're curious about going electric eventually. The Motor Upgrade Kit makes the Push+ the only cart here with a credible upgrade path.
- You want a published braking system — dual rear brakes are described; the PX4's page is silent on this.
- You want the sand-bottle holder and magnetic accessory mounts in the box.
- Saving $31 at list, and keeping the upgrade option, outweighs the weight difference for you.
The Bottom Line
The PX4 is lighter, warrantied longer on the frame, and ships with dual umbrella holders and a valuables pouch. For most golfers who want a push cart and nothing else, it wins the comparison. The Alphard Cybercart Push+ is the one to buy if you might want to go motorized at some point — that upgrade path is real, it's Alphard's own kit, and you'd be paying $299 now instead of buying a whole new electric cart later.
