FLAGSHIP MODEL
The Mach One S.
Everything we learned from a hundred numbered Mach Ones, refined into our new flagship. 6,000 watts, 70km/h, 50km of real-world range — in stock and built to be ridden hard.
SIX YEARS OF OBSESSION
We didn't build the fastest board. We built the one we'd never get off.
Every part earned its place — or got cut. The Mach One S is what's left when you refuse to compromise: relentless power, a ride that disappears beneath you, and the kind of build quality you feel the first time you step on.
Stand still. Move fast.

THE MACH ONE S
All the thrill.
None of the baggage.
The Mach One S was made for risk takers. For rebels. For people who challenge ordinary. Six years of refinement — engineered for riders who won't compromise. A board that does it all, built by skaters who ride their own gear.
Effortless power. Brutal when you want it.
The Ultimate Control
Carves like it's reading your mind.
The combination of a rigid deck and soft suspension makes for a ride that feels like you're completely isolated from the ground — yet you can feel exactly what the wheels are doing. An experience unlike anything else.
Daily ride or weekend escape.

ENGINEERING
Over-engineered. On purpose.
Over 90% designed and developed in-house. Custom motors. Suspension swing arms. Carbon fibre monocoque chassis under a bamboo-composite deck. Every component stress-tested until something breaks — then redesigned so it never breaks that way again.

F55 DARKSTAR MOTORS
Because good enough
never is.
Redesigned from the ground up — improved cooling, a larger stator core, custom bevel-shaped magnets, and a new shaft mounting system. More than 10% increase in power output over a motor that was already the best in the category. It also runs cooler and more efficiently.
NEW DECK
Designed to be yours.
The bamboo core fibreglass composite addresses the original's cost without sacrificing rigidity or ride quality. Affordable enough to own a spare, easy enough to modify to suit your riding style. Gloss clear-coated enclosure with exposed carbon twill. Available in Jet Black and Rosso Corsa.
REFINED CHASSIS
Six years. Still getting better.
Derived directly from the original Mach One and further enhanced. New bushing compounds for superior isolation from road vibration, improved water sealing, new forged 10mm axles, and a narrowed front truck for sharper steering response.
SR125 V3 WHEELS
The best of both worlds.
50g lighter per wheel. Kegel compatible straight out of the box. Less unsprung mass means better handling — and now three different compounds to play with. Urethane feel, rubber grip. The first of their kind.
NEW REMOTE
You asked. We listened.
OLED display showing live board data. Hall-sensor throttle for precise control. Adjustable power modes. 12 hours of battery life. CNC machined 6061 aluminium frame. It feels as premium as the board it controls.
