The e-Storia features much of the same technology of the Storia V3 but in a more robust package built specifically for the stresses involved with the higher vehicle weight of E -bikes and tailored to provide ultimate control for all riders from the enthusiast to those at the elite level of E-bike enduro riding.

While the Storia V3 is built for best-in-class weight and performance the e-Storia is designed with an emphasis on toughness to drastically improve reliability over dampers without dedicated E-bike construction.

The stronger shock design can help increase the lifespan of bike chassis components as well, and increase range of tune-ability accommodating a wider range of bike and rider types.

An industry “first” an ultra-high performance suspension specifically designed for aggressive E-bike riding and super comfort level for professional riders and all enthusiasts.
