KingSong S22 Pro review

The S22 Pro is the old trail favorite, sold today with its known weak points fixed in advance. eWheels says its red and black units ship with the fourth-generation 4 kW motor, an upgraded slider kit and stronger suspension bolts. For $2,499 on November 13, 2026 you get that, a 1,776 Wh battery of high-discharge Samsung 40T cells and 75 mm of coil-sprung travel at 77 lb. It scores 8.0/10. The reason it isn't higher: the newer V14 Pro costs the same and brings 2,400 Wh and a published IPX6.

Its product page is specific. The red and black S22 Pro units get the Gen 4 4 kW PRO motor, "premium Hou Ningning Slider Kits", and upgraded suspension linkages and motor bolts. The Anniversary Edition in gold ships as it leaves the factory, with the 4 kW motor and KingSong's own sliders.

Why it matters: the sliders are the rails the suspension travels on, and a suspension wheel is only as good as those rails. A reseller that swaps them before you ride is selling you fewer evenings with a hex key. The cost is time. eWheels says the custom work can delay shipping by up to a week.

The recipe is classic: a tall 20-inch tire to roll over roots, a DNM Burner coil shock with 75 mm of usable travel, and high-discharge cells that deliver current in bursts, which is what climbing and jumping ask for. You choose a street or a knobby tire at checkout. Take the knobby if dirt is the plan.

Seventy-five millimeters is the shortest travel in our off-road electric unicycle ranking, where the S22 Pro sits No. 10 of 10. Newer wheels reach 90 to 100 mm. If you are choosing between KingSong's two trail wheels, KingSong F18 vs S22 Pro shows what the extra $550 buys.

On November 13, 2026 both cost $2,499. The V14 Pro gives you 2,400 Wh against 1,776, a 309 lb load limit against 265, IPX6 in writing, free shipping, and on that day a free helmet. On paper it is the better buy, and our formula says the same: 8.9/10 against 8.0/10.

The S22 Pro's case is format: 9 lb lighter, a bigger 20-inch wheel, a DNM coil shock and a reseller's inspection before it ships. Read InMotion V14 Pro vs KingSong S22 Pro before you decide.

eWheels' page doesn't list the box contents. It does say a 5 A charger is included and that the wheel comes with spiked pedals, integrated adjustable power pads and a built-in kickstand. You pick the color and the tire, street or knobby, at checkout.

Check bolts and tire pressure after shipping, charge fully (4 to 6 hours on the 5 A charger) and update the firmware in the KingSong app. Set the shock's preload for your weight before the first trail. Adjust the power pads so your shins sit comfortably against them; they change how the wheel accelerates and brakes.

Before the first ride, a helmet and wrist guards at the very least: our electric unicycle safety gear guide lists what riders wear at each speed. Rules change by state and by city, so check where an electric unicycle is legal to ride before you plan a commute around it.

Shipping is calculated at checkout: eWheels ships by FedEx and doesn't offer free delivery on wheels. A 10 A charger halves charging time and is sold separately. Suspension sliders and bushings are wear parts on any wheel of this type. Returns are for unopened boxes within 14 days, and you pay shipping both ways.

Per watt-hour of battery, that is $1.41: the figure our tie-break uses when two wheels land on the same score.

Each criterion is marked from the figure eWheels publishes; anything the page doesn't publish gets the lowest mark. Claimed top speed is not a criterion. The weighted result is placed on our 7.5 to 9.6 scale. This wheel rounded to the same figure as the one ranked just above it; the published tie-break (price per watt-hour, then weight) places it one step below, so that no two wheels show the same score. The scales and the weights are on our methodology page.

$2,499 at eWheels on November 13, 2026. Sale price at eWheels on November 13, 2026; eWheels lists $3,200 as the regular price.

One step up, the Leaperkim Patton-S is $2,899 for 8.3/10. We link to eWheels because that is where we read the price and the stock.

The two closest in price: InMotion V14 Pro ($2,499, 8.9/10) and Leaperkim Patton-S ($2,899, 8.3/10). Put all three side by side.

Head-to-heads: InMotion V14 Pro vs KingSong S22 Pro, KingSong F18 vs KingSong S22 Pro.
