Ride The Rails On A OneWheel

The US has tons of abandoned rail, especially in urban environments, so it seems a shame to let it go to waste. [OneWheel] decided to modify one of their boards to ride the rail behind their office.

The stock OneWheel frame was sectioned and CNC cut mounts were placed in the center to raise the motor above the deck. Steel rail wheels sourced from eBay were then attached to an axle run through where the original wheel was mounted in the center. The motor housing was turned down on a lathe for better clearance, and then a bike sprocket was attached to chain drive the train axle.

While not everyone has a hydraulic press and a CNC for that professional look, we don’t see any reason you couldn’t bodge something similar together at home. Be sure to watch [Bradley Gawthrop]’s Supercon talk on the Personal Electric Vehicle Revolution for some ideas on what you need to get started.

Dream of riding the rails yourself? You should checkout this tiny rail riding pod car or this more minimalist example. Definitely make sure you’re riding on a truly abandoned line or get a rail warrant though!

Building A One Wheel With Tracks

February 21, 2025 by 6 Comments

One-wheels use motion-tracking hardware and fine motor control to let you balance on a single wheel. That’s neat and all, but [Michael Rechtin] had another idea in mind—what if a one-wheel used a track instead?

The idea behind the track was to make the one-wheel more capable on surfaces where wheels simply can’t compete. The tracked drivetrain was largely 3D printed, including some massive gears that are supplemented by a big old 150 mm ball bearing which sits around the drive motor itself. If you love planetary gear trains with a 4:1 reduction, this project is for you. Carbon-fiber reinforced filament was used for many of the parts to give them some additional strength. Control is a little different than a traditional one-wheel, since the flat-bottomed track means lean controls won’t work. Instead, a wireless hand throttle was constructed to enable the rider to command the direction of travel.

It’s not easy to ride, but the one-track does actually work. It’s capable of crawling its way around on grass and snow quite well. There were some issues with the printed tracks and rollers, particularly when turning, but tweaks to round out the track profile helped solve that issue to a degree. There’s a reason we often use wheels instead of tracks, but somehow tracks are still just cool.

YouTuber Builds Onewheel With Tracks Instead And It’s Not Great

The one-wheel is a triumph of modern sensor and control technology. That made it possible to sense the acceleration and position of a platform with a single wheel, and to control that single wheel to keep the platform stable and level, even in motion. [RCLifeOn] has now taken that same concept and made it more hilarious by swapping out the wheel for a track.

The original idea was to build an electric snowboard, which worked just okay. Then, it morphed into a tank-based one-wheel instead. It’s a bit silly on the face of it, because a track is more stable than a wheel. That’s because instead of balancing on a small flattened spot of a tire, it’s got a wider, flatter footprint. But that means there’s no real need for balancing control as the track is statically stable.

The 3D-printed track assembly is driven by a powerful brushless motor via a gear drive for additional torque. Riding it is difficult on 48-volt power as it easily throws [RCLifeOn] off the board with its raw torque. At 24 volts, however, it was just barely ridable with some practice. But it was ultimately pretty terrible. It was either not moving at all, or jerking so hard that it was impossible to stay on the thing.

We’d like to see this concept tried again, perhaps with a rubber track and a more refined controller. Video after the break.
