Short answer: KingSong F18 wins this one, 9.2/10 against 8.0/10, mainly on battery capacity and suspension. KingSong S22 Pro answers with price and weight.
What really separates them?
KingSong's new trail flagship against its older one, $550 apart. The F18 moves every number: 5,000 W against 4,000 W, 2,664 Wh against 1,776 Wh, 100 mm of travel against 75 mm, a 309 lb load limit against 265 lb, and a 10 A charger in the box. It also weighs 13 lb more. The S22 Pro's case is price and weight, plus the upgrades eWheels fits before shipping. If you ride hard trails or come close to the S22 Pro's 265 lb limit with gear, the F18 is the one. If you want a 20-inch suspension wheel for less and can live with a smaller battery, the S22 Pro still does the job.

KingSong F18: 5,000 W (9,000 W peak) motor, 2,664 Wh on a 133.2 V system. KingSong S22 Pro: 4,000 W motor, 1,776 Wh on a 126 V system.
The F18 has the stronger motor, by 1,000 W nominal. The F18 has the bigger battery, by 888 Wh. As for speed, the published figures are 67 mph, per KingSong for the F18 and 43.5 mph cruising speed, per eWheels for the S22 Pro. Those are the sellers' figures, not speeds to plan a ride around, and they are not part of our score: motor power is. For range, compare watt-hours; our electric unicycle range guide shows how to turn them into miles.
Which one rides more comfortably?
KingSong F18: four-point DNM suspension, 100 mm of travel, on a 20 in all-terrain (2.75-14) tire. KingSong S22 Pro: DNM coil shock, 75 mm of usable travel, on a 20 in (2.75-14), street or knobby tire.
The F18 has 25 mm more travel, which counts on curbs, roots and broken pavement. Rider load: 309 lb for the F18, 265 lb for the S22 Pro, gear included.
Which one is easier to live with?
F18: 90 lb, trolley handle built in, kickstand; charging: about 2 to 3 hours with the 10 A charger, per KingSong. S22 Pro: 77 lb, trolley handle built in, kickstand; charging: 4 to 6 hours with the included 5 A charger; accepts up to 10 A.
The S22 Pro is 13 lb lighter, which matters every time stairs or a car trunk are involved. Published protections: KingSong F18, IPX6 and a smart BMS; KingSong S22 Pro, a smart BMS. A water rating we can't read on the seller's page is a rating we can't count. Whichever you pick, a helmet and wrist guards go in the same basket: see our electric unicycle safety gear guide.
