RADIUM BOARD
Mach One S Electric Skateboard
Six years of in-house engineering — swing-arm suspension, a carbon-fibre monocoque chassis and a bamboo-composite deck. The full story lives on the tech pages; this page is simply where you make it yours.
Please note: RTS torque vectoring is not included on the Mach One S. RTS is only fitted to the original Mach One.
Built in small batches. Orders ship within weeks.
Overview
The Mach One S builds on everything we've learned after more than six years of making high-performance electric skateboards.
It's a ground-up refinement of the original: new F55 Darkstar motors, an 18S high-voltage system and a re-tuned chassis with softer, more precise steering. Faster to charge, easier to live with, and dialled for comfort — without giving up the performance the Mach One was known for.
Features
- New F55 Darkstar motors — our most powerful and efficient yet, exclusive to the Mach One S. Same 6485 footprint, but a 10% larger stator core, custom bevel-shaped magnets, a new shaft mount, unique bearing arrangement and improved cooling.
- New remote — telemetry display, 12-hour battery, hall-sensor throttle, ergonomic design and adjustable power modes.
- Bamboo-core fibreglass deck — reduced width and a re-developed profile tuned for comfort.
- Automotive paint finishes — gloss clear-coated exposed carbon-twill enclosure; deck in Jet Black or Rosso Corsa (Racing Red), with more colours to come.
- New 18S high-voltage system — greater efficiency and headroom for future upgrades.
- New JK ESC — custom current control and smart reverse.
- Refined chassis — improved bushing compounds and gasket design for better isolation from road vibration; a narrower front truck and custom Radium bushing for soft but precise, stable steering.
- New SR125 V3 wheels — Kegel-compatible out of the box and 50 g lighter each for sharper handling.
- 60-grit glass grip tape — keeps you locked into the comfort-focused deck.
- Proven belt-drive system — the reliable drivetrain we've refined over years.
