Fizik Aidon X5 Saddle

The Fizik Earth Aidon X5 is a ride-compliant, e-Bike saddle designed to complement the experience of riding a pedal-assisted full-suspension mountain bike.

As part of the 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.

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.

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.

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.

Additionally, to increase comfort, the Aidon 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.

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, Fizik used their closed-loop Mobius rail system for increased structural stability and responsiveness.

Who’s this item for: Fizik says this is an e-bike specific saddle but it would also be a great choice for anyone that likes to ride off-road, from singletrack to gravel and everything in between.
