EWS x Prologo Proxim W450 Saddle

The official saddle of the Enduro & E-Enduro world series - The Proxim W450 EWS.

We got in touch with our friends at Prologo with a brief: “We want you to create an innovative  e-bike and Enduro saddle. Amaze us."

With these few words Prologo launched a design challenge at the Politecnico University of Milan. From this came Prologo's best saddle yet. Finished off with exclusive EWS-style topographical graphics.


  • MSS - Multi Sector System:Proxim W450 introduces this new revolutionary technology. Three different individual zones mapped and separated along the saddle, each composed of different interactive foams and single-cell padding. These areas work independently adapting to all the positions that cyclist can take.
  • The Materials: Tirox light alloy steel rail, offering strength, flexibility and lightness (225gr). The cover is made of grippy material to help steer the bike downhill and find your position easily.
  • The Shape:Semi-round shape, 250mm long and 145 mm width. Along the edges, Proxim W450 is more flexible allowing greater freedom of movement and facilitating each pedal stroke.
  • Ergonomic channel:W450 is a versatile saddle suitable for many uses and disciplines. In the central area, the active foams and the central groove guarantee stability and comfort by dissipating the pressures along the whole surface of the saddle.
    The closure of the prostate zone also offers better protection of genital areas in extreme climatic conditions (water and mud).
  • Rear Cover:Designed to increase grip in all weather conditions.
Rear handle and reflective graphics:The saddle is equipped with a rear "handle" to facilitate the movement of the bicycle as well as a graphic with reflective materials to improve safety.
