Features

Aido: Control and Comfort For E-MTB Power

As part of the new Fizik range of short-nosed saddles, the Aidon is specifically designed for use with full-suspension E-MTBs. The shorter shape puts riders in a more planted position, making for greater stability, confidence and control when riding heavier pedal-assisted bikes.

Seamless Shifts, Solid Support

A gradual transition from nose to side wings allows smooth position changes while guiding the bike. The waved kick tail provides lower-back support to help riders hold their position while tackling technical climbs as well as giving greater control during the electric kick of assistance.

Designed To Move With You

Once you've conquered the climbs and you head downhill with your dropper post lowered, the saddle becomes a control device. The Terra Aidon's rounded contours allow smooth and fast movement of your legs around the saddle to help you stay on course.

Engineered For Seated Power

Since more time is spent in a seated position on an E-MTB than during traditional riding, the Terra Aidon features a specific ergonomic cut- out, designed to relieve pressure on sensitive areas. A rubber layer at the bottom of the cut-out functions as a mud flap, blocking unwanted dirt and spray from the trails.

Type-2 Foam

Additionally, to increase comfort, our E-MTB saddle is padded with a proprietary Type-2 foam that's thicker around the ischial sit bones area to support a more upright riding posture, as well as on the sides for better manoeuvrability and comfort while pedalling at a high cadence.

Higher Level of Flexibility

For pedal-assisted all-mountain use, the Terra Aidon has been engineered with a compliant shell to offer a higher level of flexibility. This controlled elasticity absorbs vibrations for increased comfort. To better support the Terra Aidon's flexible shell, we used our closed-loop Mobius rail system for increased structural stability and responsiveness.
