YouTuber James Bruton has created a “screw bike” in the vein of screw-drive tanks, with the additional feat of making it self-balancing. Building upon an earlier front-omni-wheeled bicycle, the latest model can move in any direction, thanks to its four mecanum wheels.

In addition to its steel frame and 3d-printed wheels, the bike features Teensy 4.1 boards to control its ODrive motors via CAN bus. BNO08x IMUs work with the Teensy to help keep things upright. The whole crazy thing can be seen in action below, with source code and CAD files available on GitHub.
