§ 01 / Philosophy

The cell-chemistry refresh.

The latest revision of the S18 platform.

The S18 PRO+ is the cell-chemistry refresh of the S-platform. The chassis stays familiar — 18″ tire, variable air suspension, telescopic trolley, ~25 kg curb weight — but the Samsung INR21700-50S cells deliver more current under hard acceleration and hold voltage better when the pack is below 30% state of charge.

Three named generations live under the S18 family. This is the latest, and the one OneRide stocks.

Charging takes around 5 hours with the 84 V / 2.5 A standard charger. UL 2272 certified pack — meaningful for indoor charging permission and shipping insurance routing. 25 kg curb weight, 120 kg max rider load, 35° max grade.

§ 02 / Systems

Four choices that define the S18 PRO+.

KingSong S-platform
Pro+ revision · 2025
01

Samsung 50S cells

High-discharge variant in Samsung's 21700 line. Less voltage sag at low state of charge.

02

Air suspension

Variable air suspension with adjustable travel. The S-platform comfort signature since 2019.

03

2200 W / 5000 W peak

Calibrated for 50 km/h sustained cruise on the 18″ wheel. Headroom for steep climbs.

04

UL 2272 certified

Pack-level certification — meaningful for indoor charging permission and insurance.

§ 03 / EnergyBattery

1110 Wh · 84 V.

Samsung 50S · UL-certified

The 50S is the high-discharge variant in Samsung's 21700 line. Practical effect: smoother acceleration when the battery is mostly empty, less alarm-cutoff drama on long climbs.

50 km/h · 35° grade

The motor and its 5000 W peak handle the spike on steep climbs. The air suspension keeps the contact patch loaded.

§ 05 / ChassisBuild & sealing

25 kg · 18″ · UL 2272.

Air suspension · telescopic trolley

KingSong does not publish a single IP class for the S18 PRO+. Treat the wheel as weather-resistant within normal urban use. UL 2272 certification on the pack is the relevant credential.

§ 06 / Who rides it

The S18 PRO+ rewards riders who value the S-platform comfort tradeoff.

A

Returning S-platform riders

Returning S-platform riders who want the latest cell chemistry without changing chassis. Same feel, smoother delivery at low state of charge.

B

The air-suspension rider

Riders who value air suspension and the 18″ comfort tradeoff over off-road specs.

C

The indoor-charge rider

Riders charging indoors who need UL 2272 certification for building rules.

×

Off-road riders

The 18″ street suspension is not a trail tire.

×

Spec-sheet shoppers

The V13 or F18 deliver bigger numbers on paper.

×

Suspension dial-in averse

Initial pressure setup matters with air suspension.

§ 07 / Technical reference

Every number that matters.

Q-01S18 vs S18 Pro vs S18 PRO+ — which is which?

S18 (2019): original LG M50LT cells. S18 Pro: Molicel P42A intermediate revision. S18 PRO+ (this page): Samsung INR21700-50S high-discharge cells. Same chassis across generations — the difference is in the pack.

Q-02Why does the cell chemistry matter?

At full throttle and below 30% state of charge, 50S cells deliver more current with less voltage sag. Practical effect: smoother acceleration when the battery is mostly empty, less alarm-cutoff drama on long climbs.

Q-03Is the 18″ tire tubeless?

Tubeless options exist; regional stock varies. Confirm your specific shipment with us before ordering if tubeless is a hard requirement.

Q-04Can I ride in rain?

KingSong does not publish a single IP rating. Treat the wheel as weather-resistant within normal urban use — splash and brief light rain are fine. Don't pressure-wash, don't ride through standing water.

Q-05Will it climb 35°?

Yes — the air suspension keeps the contact patch loaded and the 5000 W peak handles the spike. Grade rating is rated, not theoretical.

Q-06EU warranty?

Two years through OneRide with home pick-up service.

Free EU delivery
