At Radium, we're not trying to reinvent the industry—we're just making something that handles properly. One of our recent innovations, the R6 Trucks, represent the culmination of prototype truck designs, engineered to push the boundaries of powered, modern skate technology.

Built to provide superior control, stability, and precision, the R6 Trucks are the heart of the Mach One electric skateboard, giving it a level of performance unmatched by anything in its class.

Here’s why we chose to go with Reverse Kingpin (RKP) trucks for the Mach One—and why we know our R6 Trucks deliver a safer, more exhilarating ride than Double Kingpin (DKP) setups found on many popular boards.

R6 Trucks: Mastering High-Speed Stability

Radium’s R6 Trucks were born out of a relentless pursuit of stability, especially at high speeds. The Mach One is a board built for serious riders who want to push their limits, and with top speeds that rival some of the fastest electric skateboards on the market, stability becomes essential. That’s why the R6 Trucks feature a 30 degree angle in the rear truck, providing rock-solid stability even when pushing the limits of speed. This setup ensures that the board remains planted, allowing riders to accelerate confidently without worrying about speed wobble or twitchy handling.

While other boards may use DKP setups to compensate for sluggish manoeuvrability, they are inherently unstable and can become dangerous at higher speeds. DKP trucks, with their exaggerated lean and aggressive turning angles, may offer deep carving at low speeds, but that same design makes them unpredictable and unsafe when you're going fast.

In contrast, the RKP design of our R6 Trucks focuses on maximising control and stability, giving the rider the confidence to push harder—with way less risk.

Precision Steering and Ultra-Responsive Handling

Radium’s R6 Trucks aren't just stable—they’re incredibly responsive. We engineered the front truck with a 60 degree angle, giving it twice as much steer as the rear. This geometry shifts the handling to the lightest end of the board, which disguises the weight of the heavy motors and results in a more agile ride. Whether you're carving hard through city streets or weaving around tight obstacles, the Mach One responds like an extension of your body.

But it’s not just about angles—our R6 Trucks feature narrow 237mm hangars. This setup makes the Mach One feel even more nimble and agile, allowing you to carve effortlessly while maintaining complete control. When combined with Radium’s advanced engineering, this responsiveness sets the Mach One apart from other electric skateboards, giving it a dynamic and thrilling feel that’s impossible to replicate with DKP trucks.

Offset Bushing System: Cornering Redefined

One of the most advanced features of the R6 Trucks is our unique offset bushing system. Unlike traditional bushing setups, the R6 uses two kingpins for significantly improved stability and feel throughout a corner. As you lean into a turn, the offset bushing design delivers smoother transitions and more consistent feedback, making every carve feel precise and controlled.

We didn’t stop there. We’ve paired the R6 Trucks with Riptide bushings, a high-performance bushing brand renowned for their responsiveness and durability. Together, this combination results in a ride that feels rock solid at speed, giving riders the confidence to push their limits without worrying about instability or unpredictable turns.

Engineering Precision: Built to Perform

We focused on getting the details right so the trucks ride the way they should. Here’s what makes them stand out:

• Custom pivot tubes ensure smooth, consistent turning.
• Super rigid 11mm hardened kingpins give unmatched strength and stability.
• Anti-slop set screws eliminate any play in the truck, providing an incredibly precise and solid feel.
• Precision bushing washers and tightly machined tolerances throughout ensure that every component fits perfectly together, contributing to the overall performance of the board.

Every aspect of the R6 Trucks was designed with one goal: to provide the ultimate ride experience. From the moment you step on the Mach One, you’ll feel the difference—whether it’s the way the trucks respond to your slightest input or how they maintain stability at high speeds. This level of engineering precision is simply not possible with the loose, wobbly feel of DKP setups.

Why RKP Beats DKP Every Time

Some electric skateboards, particularly those we like to call “toy boards,” use Double Kingpin (DKP) trucks as a crutch to deliver an illusion of carving ability. However, this deep lean comes at the cost of stability, especially at higher speeds. DKP setups may feel like they carve better, but in reality, they’re prone to instability, and their exaggerated lean can lead to unpredictable, even dangerous, handling when riding fast. These toy boards sacrifice safety for carving, making them unreliable for serious riders.

In contrast, the RKP design of our R6 Trucks is all about finding the perfect balance between carving and stability. R6 Trucks provide precision steering that allows for tight carves, but without the instability of DKP systems. You get all the fun of carving without the risk that comes with unpredictable steering angles at speed. With the Mach One, you’re not just getting a carving board—you’re getting a performance machine that feels stable, precise, and in total control.

Conclusion

Radium’s R6 Trucks are the result of years of innovation and a relentless pursuit of high-performance precision. By combining advanced downhill skate technology with innovative engineering, we’ve created a truck system that is stable at speed, responsive in handling, and built for ultimate performance. R6 Trucks provide the perfect balance of carve and control—giving riders the confidence to push the limits and experience what true electric skateboarding can be.

With the Mach One, you’re not just riding a board—you’re riding the future of electric skateboarding. And with the R6 Trucks, you’re in full control.
