Carl Quitoriano :
structural durability will become issue in due time. axial mis-alignment along the magnets in due time coz magnetic repulsion doesn't fold them locked in alignment but repulsion in all directions. pls see what I researched :
Yes, the structural integrity concerns you raise about permanent magnet bike shock absorbers are valid, especially with the seat suspended mainly by repulsion forces that could introduce twisting and misalignment over time.Mechanical WeaknessesRepelling magnets on the front (near seat tube) and back create axial lift but lack lateral constraints, allowing side-to-side or torsional play that stresses frame joints.� Without precise alignment guides or dampers, off-axis bumps amplify twisting forces on the seat post, potentially fatiguing welds or pivots quickly.�Durability IssuesReal-world demos like Colin Furze's show initial smoothness but joint failures under aggressive riding, as magnets transmit vibrations directly without energy absorption.� Neodymium magnets resist demagnetization for decades, but frame aluminum or steel wears faster from uneven shear loads, unlike traditional spring/oil systems with inherent stability.��Practical FixesAdding bushings, eddy current brakes (copper sleeves), or rigid linkages could mitigate disorientation, but this adds complexity and weight, negating the "simple" appeal.� These remain novelties, not production-ready due to these alignment risks.�
