Mad-as-a-hatter British inventor Colin Furze lately got down to create a real-life model of the hoverboard from Again to the Future II. Technically, he failed. However what he constructed alongside the way in which has its personal appreciable benefit: a double-deck skateboard the place the highest platform floats above the decrease one by the repulsive drive of neodymium magnets.
Furze has constructed a profession out of turning insane premises into functioning machines like retractable Wolverine claws, a jet-powered bicycle, and a hoverbike produced from paramotor engines. His newest venture, the Magboard, builds instantly on an earlier experiment – the Magnet Bike, a fat-tire mountain bike that used two pairs of magnets with greater than 500 kg (1,102 lb) of pull drive every to switch coil/spring suspension, already proving the idea might survive real-world wheels and highway vibration.
The thought for the Magboard got here from a YouTube remark. A person named Don Brown – who seems to be one of many founders behind the Etnies shoe model – requested: “Are you able to do that with skateboard vans?” Furze beloved the concept, set to work, and, after at the very least seven or eight prototypes, landed on a board that not solely levitates however steers and rides identical to a traditional longboard.
The MAGNET Suspension SKATEBOARD
Furze constructed two decks, put magnets between them in order that repelling drive created an air hole. The decrease deck carries the vans (the metallic axle assemblies that maintain the wheels) and the higher deck is the place the rider stands.
The actual problem wasn’t making it float, that labored inside three minutes of the primary prototype, however making the meeting steerable and steady with out the highest deck wobbling like a damaged purchasing cart. Furze tried linear pins, bearings, hinges, cross-brake cables, and combos of the entire above. The ultimate model makes use of sq. tubes with bearings built-in into 3D-printed sleeves, which permit vertical motion with minimal friction whereas nonetheless transmitting the rider’s foot rotation to the vans.

The longboard-sized base deck makes use of two layers of 12-mm (0.47 in) polycarbonate as a result of one layer alone was too versatile. The magnets are the identical 100 x 30-mm (3.9 x 1.2-in) discs used within the bicycle venture.
“Bouncing on magnetism is totally completely different,” Furze famous within the video. “It is like frictionless. It genuinely looks like an air cushion.” To show the purpose, he strapped a glass of water to a traditional longboard and in contrast it to the Magboard on grooved concrete. The water barely rippled within the magnetic model, whereas it visibly sloshed in the usual one.
As typically occurs with Furze’s innovations, one wonders whether or not this goes past a mad yard YouTube experiment. For now, limitations are actual: it performs finest on easy surfaces, weighs significantly greater than a regular skateboard, guidelines out ollies (the foundational jump-and-flip trick in skateboarding) and any airborne maneuver, and the added peak raises the middle of gravity.

That stated, the design solves an issue no earlier hoverboard try had cracked: freedom of motion. Designs that levitate objects over copper plates or superconducting rails work, however they tether you to the scale of the platform or the size of the rail. Furze’s Magboard goes wherever you go. “In contrast to a hoverboard, which has no connection to something, this works, and you’ll steer it,” the inventor stated.
Furze acknowledges that he hasn’t solved each downside but, and has requested his group for concepts to get rid of the final seen mechanical parts. However the idea may need actual implications for private transportation.
A suspension system with no instantly contacting mechanical components means, in idea, zero friction put on on the damping mechanism, providing a doubtlessly important benefit for city electrical scooters navigating cobblestones and cracked asphalt. Generally essentially the most fascinating engineering advances begin from an concept everybody else scrolled previous.
