Photos: This self-balancing e-bike uses single massive sphere to carry rider

Inventor James Bruton has developed “Ike,” a self-balancing e-bike that uniquely rides on a single large sphere, requiring continuous computer-controlled adjustments to maintain stability across two axes while carrying a rider. Unlike his earlier prototype, this design reduces the contact point to one ball supported by three custom-built omni-wheels arranged in a triangular frame. These wheels feature aluminum cores, multiple bearings, and 3D-printed TPU tires to provide traction and withstand the rider’s weight. The drive system is powered by three 2 kW brushless motors connected via belt drives, with power supplied by six lithium-polymer batteries configured to deliver 50 volts and increased capacity. Safety features include a large contactor and emergency stop switch, while sensitive electronics are shielded with nickel spray to prevent interference caused by static electricity from the ball. The chassis is constructed from 40/40 aluminum extrusion, forming a rigid triangular box that supports the internal components and maintains the geometry needed for stable operation. Rider input
