adjustable geometry

With a Flip Chip system that allows you to adjust the frame geometry quickly and easily. Modify the head angle and rear triangle to adapt the bike to your riding style or the type of route. One frame, four possible configurations. Maximum versatility for riders who want it all.

design and kinematics

The Reason revolutionizes the e-bike segment with a high-performance, lightweight frame and outstanding kinematics. It absorbs vibrations without losing responsiveness, delivering agility, control, and precision at all times. Its integrated, sleek, and clean design looks like a muscle bike: no one would say it’s electric, not even up close.

Leverage ratio

The Reason features progressive kinematics with a 21% leverage ratio, ensuring a sensitive suspension at the start of the travel and progressively firmer towards the end. This behavior improves traction, comfort, and prevents bottoming out on jumps or large impacts. It also allows fine tuning through tokens or volume spacers in the shock, adapting to different riding styles. A smooth, controlled, and balanced curve, ideal for Trail, Enduro, and e-bikes.

Progression
21%

Anti-Squat

The Reason features an optimized and balanced anti-squat curve, firm when pedaling and sensitive when the terrain demands it. With values from 108% to 104% at SAG, it eliminates pedal bob while maintaining stable and efficient suspension on climbs. Its progressive drop to 65% improves traction under heavy compressions, achieving a perfect balance between performance and sensitivity.

efficiency
108%

Anti Drive

The Reason features a progressive anti-dive curve around 55%, allowing control during intense braking without excessively stiffening the front suspension. This value sits within the optimal range (50–70%) for Trail and Enduro, ensuring stable handling, an active fork, and a natural feel in technical sections where the balance between absorption and control is key.

Anti-Drive
60%

Kick-Back

The Reason features a progressive kick-back curve with a moderate value of up to −20°, perfectly balanced for a trail/enduro e-bike. This figure falls within the ideal range, minimizing interference during technical pedaling without compromising sensitivity on descents. The result is an active, predictable suspension with excellent traction, ideal for making the most of motor assistance on any terrain.

Connectivity
Intuitive and customizable interface

Thanks to the integrated Avinox drive system, the Reason allows users to easily record all ride data. Through advanced sensors collecting nearly 50 metrics, it is possible to customize the control screen from the Avinox app, including information such as ride duration, range, average speed, and real-time power.

Wireless controllers

Dual wireless controls that connect via Bluetooth to the main display. This eliminates cables, simplifies maintenance, and allows quick switching between assistance modes, giving faster access to multiple functions and commands.

Smartphone connectivity for enhanced security

The Avinox mobile app unlocks the full potential of the system. Once paired via Bluetooth, it allows you to secure the bike, manage ride data, customize assistance levels, and monitor the e-bike status in real time. It also provides alerts for unusual movements and other smart features.

Customizable parameters

After syncing with the Avinox app, riders can adapt the parameters displayed on the control screen to their preferences and riding style. Settings can also be adjusted directly from the mobile device based on each ride’s needs.

Bike protection

When the bike is connected to a smartphone via Bluetooth, it can be automatically unlocked when you approach. In addition, the system includes security features that send alerts to your phone if unusual movement is detected, helping you maintain control over the bike’s location and status at all times.
