KingSong F18 review

The F18 is the best big wheel on our list, and it is No. 2 of 15 overall. KingSong pairs a 5,000 W motor with a 2,664 Wh Samsung 50S battery and the longest suspension travel we list, 100 mm, on a magnesium chassis. The included 10 A charger fills it in two to three hours, which changes how you use a wheel this size. At $3,049 on KingSong's US store on November 13, 2026 it was $150 cheaper than at eWheels. It scores 9.2/10. The catch is 90 lb, and a return policy you should read twice.

Travel and adjustment. KingSong calls it a four-point DNM suspension with 100 mm of travel, and lets you set compression damping, rebound damping and spring preload. eWheels, which also sells the F18, counts 25 damping levels and says the tuning needs no tools.

In practice that means one wheel with two characters. Soft and slow-rebounding for a rooty trail, where the tire needs to stay on the ground. Firm for the road, so the wheel doesn't wallow when you brake hard. A hundred millimeters is also what keeps a landing from bottoming out. It is why the F18 leads our off-road electric unicycle ranking.

Most big wheels ship with a 5 A charger and a battery that takes most of a night to fill. KingSong puts a 10 A charger in the F18's box and quotes about 2 to 3 hours for 2,664 Wh. With two chargers on the dual ports, the wheel accepts 20 A, and KingSong quotes 1 to 2 hours.

That turns a long ride into two rides with lunch in between. Ride 40 miles out, eat, plug in, ride home on a nearly full pack. For group rides and touring, charging speed is worth as much as raw capacity. The F18 ranks No. 2 of 10 in our long-range list on capacity alone; the fast charger is a bonus our formula doesn't even count.

eWheels itself describes the F18 as "a worthy competitor to the bestselling Lynx". On the pages we read, the F18 has the stronger motor (5,000 W against 3,800 W for the Lynx-S), more travel (100 mm against 90), a published IPX6 line, and a lower price: $3,049 against $3,699.

The Lynx-S answers with a 330 lb load limit and a seat kit in the box. Against the cheaper Patton-S, the question is whether you need the bigger wheel at all: see KingSong F18 vs Leaperkim Patton-S. And if you are moving up from KingSong's older trail wheel, F18 vs S22 Pro is the one to read.

KingSong's page doesn't publish a box list, but its battery section says the 10 A charger is included. The page also mentions adjustable pedals and an integrated trolley handle as standard. Ask about power pads and tire choice (eWheels offers street or knobby) before ordering.

Unbox with a second person. Charge fully, pair the KingSong app and run the firmware updates: KingSong says the mainboard, display board and BMS all update over the air. Set preload for your weight first, then compression and rebound. Pick one of the pedal heights and angles, then leave it alone for a week before you judge it.

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 free from a US warehouse, per KingSong. A second 10 A charger is the upgrade for 20 A charging. Returns are the cost to respect: 14 days, unopened and unused, with a handling fee of $250, or $350 on heavy wheels. At this power, gear means a full-face helmet, wrist, knee and elbow protection.

Per watt-hour of battery, that is $1.14: the figure our tie-break uses when two wheels land on the same score.

Each criterion is marked from the figure KingSong 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. The scales and the weights are on our methodology page.

$3,049 at KingSong on November 13, 2026. Sale price on KingSong's US store on November 13, 2026; KingSong lists $3,499 as the regular price. eWheels sold it for $3,199 that day.

If that is more than you planned, the Leaperkim Patton-S costs $2,899 and scores 8.3/10. We link to KingSong because that is where we read the price and the stock.

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

Head-to-heads: KingSong F18 vs KingSong S22 Pro, KingSong F18 vs Leaperkim Patton-S.
