A stable fold mechanism and a secure bag strap system matter more day-to-day than extra accessory mounts.
A push cart is one of the best fatigue-saving purchases available to golfers who walk most of their rounds, letting you carry a full bag's worth of gear without carrying its weight on your shoulders.
Fold mechanism and stability
A one-button or single-action fold mechanism is a genuine daily convenience versus a fussier multi-step fold — you'll notice the difference every single time you load and unload from a car trunk. Check that the cart stands stably on its own once folded, not just when open.
Bag strap security
The strap or cradle system needs to hold your bag securely on uneven terrain and hills without shifting — a bag that tips or slides on a slope is more than an annoyance, it can damage clubs or the cart itself over time.
Accessory mounts
Umbrella holders, cooler bag mounts, and phone/scorecard holders are genuinely useful if you'll actually use them, but shouldn't be the deciding factor over fold mechanism and strap security, which affect every single round.
3-wheel vs. 4-wheel
3-wheel carts are generally lighter and easier to store; 4-wheel carts tend to be more stable on hilly terrain and some fold flatter for trunk storage. Either is a reasonable choice — prioritize the fold mechanism and strap quality within whichever format you choose.
