RADIUM TECHNOLOGY
Engineered from scratch.
Every component on a Radium board is purpose-built. No off-the-shelf parts. No shortcuts. This is how it's made.
THE RADIUM DIFFERENCE
Most boards bolt motors to a longboard. We started with a blank sheet.
Chassis. Suspension. Motors. Drivetrain. Firmware. Every major system designed in-house — so every part is built to work with every other part. That's not a feature list. It's a philosophy.
RADIUM TORQUE STEERING — PATENTED
Lean harder.
The board leans with you.
The first torque-vectoring system ever fitted to an electric skateboard. Independent motor control reads your steering input and shifts power to the outside wheel through every carve. Exclusive to Radium.
HOW RTS WORKS
Power that follows your intent.
Each wheel is driven by its own motor. As you lean, the system feeds more torque to the wheel that needs it — sharpening turn-in, killing slip and holding your line at speed. Not a traction-control bolt-on. Engineered in from the first sketch.
SUSPENSION
Like wearing a glove.
We asked a heretical question: why use heavy, expensive shocks when a re-imagined bushing system could ride better? Liam rode the prototype daily for over a year to find out. The answer changed the board.

RIDE FEEL
Isolated from the road.
Connected to it.
Rigid where it counts, compliant where it matters. The suspension soaks up the chatter that wears you down on a long ride, while keeping you locked in and reading every surface beneath the wheels.

PURPOSE-BUILT MOTORS
200 hours of R&D.
On a single motor.
Our 6485 wasn't repurposed from a drone or a scooter — it was designed for the loads an electric skateboard actually sees. It runs cooler, pulls harder and lasts longer. Other brands now run Radium motors in their own boards.
DRIVETRAIN
Built for the way you ride.
Custom stator cores, bevel-shaped magnets and a redesigned shaft mounting system — every detail tuned for torque, heat and longevity under real-world abuse. The power gets to the ground without drama.
CARBON FIBRE MONOCOQUE
One kilogram. Built from nothing.
A 1kg carbon-fibre chassis, laid up in-house with zero prior composites experience. A full year of failed moulds, melted plugs and cracked layups before the first good piece came out of the tool. We learned it because no one would do it for us.
THE LONG WAY
Stiffer. Lighter. Stronger.
Carbon doesn't flex where you don't want it to — so the power you put in goes into the ride, not into the deck. Every layer is oriented by hand for stiffness exactly where the board needs it.
![More volts. [br]Less compromise.](http://radium-performance.com/cdn/shop/files/InShot_20250414_141900228.jpg?v=1785182584&width=1600)
75.6V HIGH-VOLTAGE SYSTEM
More volts.
Less compromise.
An 18S high-voltage architecture delivers power more efficiently — more usable range, a stronger top-end and less heat through the system. The electrical platform was designed around the board, not the other way around.
REMOTE & FIRMWARE
The brain in your hand.
An OLED remote showing live board data, a hall-sensor throttle for precise control, and firmware written in-house so the ride keeps getting better long after you buy. CNC-machined 6061 aluminium, 12 hours of battery — it feels as premium as the board it controls.
SR125 V3 WHEELS
The best of both worlds.
50 grams lighter per wheel, Kegel-compatible out of the box, and three compounds to dial in your ride. Less unsprung mass means sharper handling — urethane feel with rubber grip. The first of their kind.
UNSPRUNG MASS
Lighter where it matters most.
Weight at the wheel is the hardest weight to hide. Shaving it transforms how fast the board reacts, how it holds a line, and how planted it feels when the road turns ugly.

And this is just the surface.
Six years of obsession, distilled into a board you can feel the first time you step on. Every system here exists for one reason — to make the ride better.
