US Patent 11046389 Ebike battery mount

An ebike comprises a front wheel, a rear wheel, a frame structure supported on the front wheel and the rear wheel, the frame structure including a hollow tube (e.g., a down tube) having a converging inner surface, and a battery assembly configured to be coupled to the frame structure in an installed position at least partially in the hollow tube. The converging inner surface is configured such that at least a portion of the battery assembly is supported within the hollow tube by the converging inner surface when the battery assembly is at least partially positioned in the hollow tube. In one embodiment, the battery assembly comprises a battery housing and a resilient lateral support, wherein the resilient lateral support resiliently laterally supports a portion of the battery housing in the hollow tube when the battery assembly is positioned in the hollow tube.
