Dynamic covalent chemistry can introduce recyclability into bio\u2010based cross\u2010linked polymers, yet a trade\u2010off between their mechanical robustness and reprocessability often persists. Herein, we report a synergistic integration of biomass feedstocks, dynamic covalent bonds, and mechanically interlocked architectures to create bio\u2010based covalent adaptable oligorotaxane networks (\n                    <jats:sup>OR<\/jats:sup>\n                    BCANs), seamlessly combining mechanical robustness, biomass\u2010derived sustainability, and circular reprocessability. These networks form through catalyst\u2010free reactions between epoxidized soybean oil and the topologically engineered polyrotaxane. Benefiting from unique force\u2010responsive behaviors of the polyrotaxanes, representative\n                    <jats:sup>OR<\/jats:sup>\n                    BCAN\u2010\n                    <jats:bold>3<\/jats:bold>\n                    exhibits exceptional mechanical properties with significantly enhanced Young's modulus (42\u00a0vs. 7.0\u00a0MPa), maximum stress (8.6\u00a0vs. 2.3\u00a0MPa), fracture strain (234%\u00a0vs. 89%), and toughness (12.6\u00a0vs. 1.2\u00a0MJ\/m\n                    <jats:sup>3<\/jats:sup>\n                    ) compared to control whose wheels are nonslidable under applied force.

This strategy bridges biomass\u2010derived platforms and mechanically interlocked architectures, opening a pathway to sustainable polymers with robust mechanical properties, extended durability, and
