The First Electric Skateboard With Torque Vectoring. Full Stop.
The Radium Mach One is unlike anything else on the market — a Formula 1-inspired electric skateboard built from the ground up by skaters who got tired of off-the-shelf parts holding the category back. At its core is RTS (Radium Torque Steering), a patent-pending torque vectoring system. Most belt-drive e-skateboards split power evenly between the rear wheels with no cross-talk between them. RTS works differently: a turning sensor reads your steering input and lean rate, then the motor controller actively biases torque side-to-side in real time — more power to the outside wheel through a turn, less to the inside one — the same principle performance cars use to rotate through a corner instead of fighting it. The result is power-assisted steering and traction that a fixed-ratio belt drive simply can't replicate. It's a world-first for powered skateboarding.
Power comes from dual Radium-developed 6485 quad-bearing brushless motors (205kv, 16kW rated), putting out 8000W combined through a MakerX DV6s motor controller — a VESC-based ESC, which in the esk8 world means a mature, well-understood platform for current control and motor commutation. The battery is a 48V, 1089Wh pack built from Molicel INR-21700-P42A cells in a 12S6P configuration: 12 cells wired in series to build the 48V nominal voltage, with 6 in parallel per group for capacity and current handling. Each parallel group (P-group) is individually fused at the balance connection, which isolates a fault to a single group instead of taking out the pack, and removes the internal balance wiring that's usually the weak point in hobby-built battery packs. On this build (16T gearing) that's enough for 64km/h (40mph) and 30–50km of range depending on terrain and rider weight.
The carbon fibre enclosure is structural — a monocoque that carries the load and houses the battery and electronics, F1-style, instead of relying on the deck for strength. The hollow carbon fibre deck bolts on as a separate, quick-swap component, so it can be changed out to suit your stance or riding style without touching the drivetrain underneath. Suspension is an adjustable swing-arm setup at each truck, fixed in yaw and roll but free to move vertically and independent of steering input — closer in concept to a single-sided motorcycle swingarm than anything else on an eskateboard. It's paired with Radium's R6 split-angle trucks: a looser 30° angle up front for quick steering response, and a tighter 60° angle at the rear for stability at speed — a deliberate trade-off rather than running matched angles front and rear. Radium's SR125 airless rubber wheels round it out, giving pneumatic-style comfort and grip without the puncture risk or pressure maintenance.

What Riders are Saying
"Wow! Wow! WOW!!! It's my seventh esk8 and definetly my last! This thing is the duck's nuts! Gotta remind myself to breathe!!!"
"Freaking-incredible!!! I own seven boards and this is now the only one I ride. I say it’s underpriced for what you’re getting. Like a high end car, you don’t realise how fast you’re going. It felt like 60km/hr (which is the max on most of my boards, which feels like 80km/hr) but on the Mach I go 70-74km/hr each ride and it is so smooth and well built it feels much slower. You won’t regret buying one."
"It's really hard to describe how breathtakingly responsive the board handles, not to mention it's awesome power in only a few sentences. The Mach One definitely takes Esk8ing & adventure boarding to another level."

Frequently Asked Questions
What is RTS and why does it matter?
RTS (Radium Torque Steering) is a patent-pending torque vectoring system — the first of its kind on a powered skateboard. A turning sensor reads your steering input and independently adjusts power to each motor in real time, giving you power-assisted steering and noticeably more traction through corners than a standard belt-drive board running fixed power split.
Why does the rear truck run a different angle to the front?
The R6 trucks use a split-angle setup — 30° up front, 60° at the rear. The looser front angle gives quicker, more responsive steering, while the tighter rear angle adds stability at speed. It's a deliberate geometry choice to reduce speed wobble without sacrificing carve feel.
Can I change the deck myself?
Yes — the Mach One's hollow carbon fibre deck is a quick-swap system, separate from the structural carbon enclosure that houses the battery and electronics. You can switch decks to suit your stance or riding style without touching the drivetrain.
Is the Mach One suitable for new riders?
It's a genuinely powerful board, and most of that power is on tap from a stop. Riders with some board-sport background tend to adapt quickly, but we'd always recommend starting cautious — light throttle, open space, and working up to faster riding once you're comfortable with the brakes and suspension feel.
How long does it take to charge?
Under 2 hours with the included Radium 12A fast charger, thanks to its resonant LLC charging design — a more compact, efficient charging topology than the standard buck-converter chargers used on most e-skateboards.
What's covered under warranty?
The Mach One carries Radium's 12-month limited warranty, covering manufacturing defects in the deck, trucks, motors, mounts, battery, ESC, and enclosure. Normal wear and tear (bearings, wheels, bushings, grip tape) and damage from water, impact, or modification aren't covered.
About Radium Performance
Radium Performance is an Australian electric skateboard brand designed and engineered in Melbourne. Founded by riders who'd spent years building and repairing their own boards, Radium set out to bring Formula 1-style engineering — structural carbon monocoques, independent suspension, and true torque vectoring — to powered skateboarding. The Mach One is their flagship board and the first production e-skateboard to feature torque vectoring (RTS).
