The Ursus King Rear R78 rear kickstand embodies Italian craftsmanship in the service of stability and robustness. Specially designed for 26 to 28-inch bikes, this rear-mounted kickstand with 18 mm spacing is the ideal solution for e-bikes equipped with mid-drive motors that prevent classic center-mount installation. Adjustable in length (263-333 mm) without tools thanks to a push-button system, it adapts perfectly to different bike heights and offers exceptional stability even when loaded.

Technical Summary

Entirely designed in Italy, it combines an anti-corrosion aluminum body with an extra-wide reinforced plastic foot that ensures excellent ground grip on all surfaces (asphalt, gravel, dirt). Capable of supporting up to 35 to 40 kg of load, it guarantees perfect stability for bikes equipped with panniers, child seats or rear racks.
