Curbs once stopped mobility—Ascender turns them into mere speed bumps. Ascender redefines outdoor mobility with its patent-pending elastic wheel system, enabling obstacle climbing up to 130% of its wheel radius—without tracks or complex multi-wheel mechanisms. Supporting over 220 lbs and reaching speeds of 13 mph, it ensures stable, smooth movement over curbs, stairs, and rough terrain. At its core lies an elastic wheel with internal support rollers that enable passive deformation. On flat ground, the wheel remains circular, but when encountering curbs or stairs, it flexes to generate additional torque and traction for seamless climbing. Optional AI-driven sensors and actuators precisely detect slopes and contact angles, automatically optimizing roller engagement for maximum grip and efficiency. Its modular architecture allows quick adaptation for delivery, patrol, and logistics applications. Ascender represents a new era of mobility accessibility and resilience—transforming everyday urban obstacles into navigable pathways of freedom.
