Kingsong S9 Basketball Electric Unicycle

Great toy!

§ 01 / Philosophy

The S9, on purpose small.
10" trainer · basketball-themed shell.

Trainer · kids · short-distance fun
KingSong S9 · Basketball edition
§ battery
155.4
Wh · 50.4 V charging

A small 155.4 Wh pack at 50.4 V — sized for the use case. Short rides, quick recharge, no surprises. Smart BMS with overcharge and short-circuit protection sits on top.

§ motor
250
W · 10 km/h top speed

A 250 W motor capped at 10 km/h. Fast enough to feel like a real wheel for a child or a learner; slow enough to keep the speed envelope honest for a 60 kg load limit.

§ shell
10"
wheel · removable tire

10-inch wheel in an aircraft-grade aluminium frame, finished in the orange-and-black "basketball" livery. Removable tire keeps maintenance trivial — the part most owners actually need to service.

The smallest, slowest, most playful wheel in KingSong's range.

The S9 is not a performance EUC and was never meant to be. It sits at the bottom of KingSong's line-up as the trainer / kids / fun wheel — 155.4 Wh, 250 W, 10 km/h, 60 kg load limit. Everything about it is sized for its job.

A 10-inch wheel for short legs, slow speeds and a basketball-themed paint job that makes it instantly recognisable.

The Basketball edition adds the orange-and-black ball-themed body design that gives the S9 its identity. Aircraft-grade aluminium alloy frame, removable tire, smart BMS, Bluetooth app connectivity (Topfeel) — a small, durable wheel built for owners who want a guest wheel, a parade wheel, or a serious-looking trainer for a child.

§ 02 / Systems

Four engineering choices sized for a 10-inch trainer.

Factory data
KingSong
S9 · Basketball · 155.4 Wh
01

155.4 Wh · 50.4 V

A small pack sized for short, slow rides. 50.4 V on charge. Smart BMS handles per-cell overcharge and short-circuit protection — the same safety architecture KingSong uses on the bigger wheels, scaled down.

02

250 W motor · 10 km/h cap

Motor power and speed envelope are both held low on purpose. 250 W is enough to start cleanly under a 60 kg load; the 10 km/h ceiling keeps the wheel inside the performance class it is designed for.

03

10" wheel · no suspension

A small contact patch on a 10-inch wheel, no suspension, no off-road pretensions. The trade-off is intentional: low weight, easy carry, easy storage, and a footprint that fits anywhere a child or guest will use it.

04

Aircraft-grade aluminium frame

The S9's frame uses an aircraft-grade aluminium alloy — light, stiff, and durable enough for a wheel that will spend its life being carried up stairs and dropped on tile. Removable tire keeps the only consumable part easy to service.

§ 03 / EnergyPack & BMS

Small pack, real BMS.

155.4 Wh · 50.4 V

A 155.4 Wh pack sized for short rides and 50.4 V charging. The BMS is the same smart, per-cell architecture KingSong uses on its larger wheels — overcharge protection, short-circuit cut-off, balanced cell handling. The trainer wheel inherits the safety stack of the rest of the range.

§ 04 / DriveMotor & speed

250 W, 10 km/h cap.

Sized for the load limit

The S9 runs a 250 W motor capped at 10 km/h. Both numbers are held low deliberately — this is a trainer / kids wheel and the speed envelope matches the 60 kg load limit. No tuning, no unlock, no surprises. The motor starts cleanly under load and tilts back well before the limit.

§ 05 / BuildShell & audio

Basketball-themed body.

No speaker · Bluetooth app (Topfeel) · removable tire

The Basketball edition adds the distinctive orange-and-black ball-themed shell that gives the S9 its identity. No built-in speaker — Bluetooth is only for app connectivity (Topfeel) — aircraft-grade aluminium alloy frame underneath, removable tire for easy maintenance. A small wheel that knows what it is and does not pretend to be anything else.

§ 06 / Who rides it

The S9 is built for short legs and short trips — kid-sized, parade-friendly, and small enough to live in a hallway.

A

Children and young learners

The 60 kg load limit and 10 km/h cap make the S9 a real EUC sized for a child. Smart BMS, aluminium frame, and the speed envelope held low so the parent stays in control of the day.

B

Trick / parade riders

The Basketball edition's orange-and-black ball-themed shell makes the S9 the most recognisable small wheel KingSong ships. A wheel that earns its keep at meet-ups, demos, and parades.

C

Big-wheel owners with a guest wheel

Owners of a Falcon, V12S or Sherman who want a small, friendly wheel for a partner, a child, or a curious friend. The S9 is light enough to carry one-handed and forgiving enough to learn on.

×

Adults over 60 kg

The load limit is real, not a soft number. Anyone above 60 kg should look at the KS-16S, KS-18XL or higher — wheels designed for the weight envelope.

×

Commuters and distance riders

155.4 Wh and 10 km/h are not commuting numbers. The S9 is intentionally not the wheel for getting anywhere fast — for that you want a 16- or 18-inch platform with a real touring battery.

×

Riders who want any speed

The 10 km/h cap is the design and there is no setting that removes it. If speed is the priority, the S9 is the wrong wheel — KingSong's KS-S22 / KS-S20 line is the answer.

Q-01 Is this an adult EUC?

No. The 60 kg load limit and 10 km/h top speed make the S9 a trainer / kids wheel. Anyone above 60 kg should look at the KS-16S or larger.

Q-02 Why is it called "Basketball"?

The body design is themed around a basketball — distinctive orange-and-black styling that gives the S9 its identity. Same hardware as the standard S9, different shell.

Q-03 Can the speed cap be unlocked?

No. The 10 km/h cap is the design — it matches the 60 kg load limit and the 250 W motor envelope. It is not a setting that owners can remove.

Q-04 Is the tire serviceable?

Yes — the tire is removable, which makes the S9's one consumable part easy to swap. The frame and shell are not designed for major user disassembly beyond that.

Q-05 EU warranty?

Two years through OneRide with home pick-up service.

Free EU delivery

2–8 working days. Carrier selected by destination and warehouse route.

2 years warranty

Home pick-up service. Battery, motor and chassis faults covered.
