Magnetic-Suspension Hoverboard Is Only 11 Years Late

Key Takeaways

• Uses repulsive neodymium magnets for suspension.
• Only vertical movement allowed; no lateral stability.
• Longboard design improves ride comfort over earlier bike.
• Vibration from pins reduces floating illusion.
• True magnetic levitation still limited without eddy currents.

Summary

Colin Furze has built a hoverboard‑style longboard that hovers using the repulsive force of four massive neodymium magnets. The device restricts motion to a single vertical axis, eliminating lateral instability by employing rear‑mounted pins and linear bearings. After early prototypes suffered from excessive vibration, Furze refined the design into a smoother longboard that, according to him, feels like a true hoverboard. The project highlights the practical limits of magnetic levitation without specialized tracks or superconductors.

Pulse Analysis

The fascination with hoverboards dates back to the iconic "Back to the Future II" vision, yet most commercial attempts have relied on wheels or gimmicky stabilizers. Colin Furze’s magnetic‑suspension board takes a fundamentally different route, leveraging the strong repulsive force of large neodymium magnets to create a true gap between deck and ground. By confining the board’s motion to the z‑axis, the design sidesteps the classic instability of magnetic levitation, offering a tangible, if limited, hover experience that feels surprisingly authentic to riders.

Technical execution proved challenging. Early versions used a bike platform with rods and linear bearings that transmitted ground vibrations, breaking the illusion of weightlessness. Transitioning to a longboard format reduced the board’s mass and allowed for a more refined pin arrangement at the rear, which dampened vibrations while preserving the single‑degree‑of‑freedom suspension. Despite these improvements, the system remains vulnerable to lateral forces, meaning riders cannot perform tricks or abrupt turns without risking loss of levitation. The project underscores how magnetic repulsion, while powerful, demands precise mechanical constraints to be viable in everyday use.

Looking ahead, Furze’s prototype sits alongside other magnetic levitation concepts such as eddy‑current hoverboards and superconducting tracks, both of which promise smoother rides but require specialized infrastructure. For the broader consumer market, the key takeaway is that affordable magnetic hover technology is still in its infancy, constrained by physics and material costs. Nevertheless, the DIY community’s ingenuity continues to push the envelope, hinting that future iterations could combine magnetic suspension with active stabilization, potentially reshaping short‑range personal mobility.
