Abstract: Presented are multi-axis pivoting coupler joints for motorized vehicles, methods for making/using such coupler joints, and electric scooters with multi-axis pivoting coupler joints enabling multimodal scooter operation. A pivoting coupler joint includes first and second bearing assemblies each with a respective housing, respective inner and outer races concentric with each other and located in their respective housing, and a respective set of rolling elements rollably interposed between their respective inner and outer races. The first inner race of the first bearing assembly receives therethrough and circumscribes an axle shaft of a vehicle wheel. The second inner race attaches to a wheeled rider deck of the vehicle. The first and second bearing housings are joined together and angularly offset from each other. For some applications, the first bearing assembly includes a pair of longitudinally spaced needle roller bearings, and the second bearing assembly includes a pair of longitudinally spaced tapered bearings.
