Adjustable Geometry
With a Flip Chip system that allows you to adjust the frame geometry quickly and easily. Modify the head tube and seat tube angles to adapt the bike to your riding style or the type of terrain. 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 an unbeatable kinematics. It absorbs vibrations without losing responsiveness, and offers agility, control and precision at all times. Its integrated, styled and clean design looks like a muscular bicycle: no one would say it's electric, not even close.

Leverage ratio
The Reason incorporates a progressive kinematics with a leverage ratio of 21%, which guarantees a sensitive suspension at the beginning of the travel and progressively more firm towards the end. This behavior improves traction, comfort and avoids bottoming out on jumps or large impacts. Additionally, it allows for fine adjustment through tokens or volume spacers in the shock absorber, adapting to different riding styles. A smooth, controlled and balanced curve, ideal for Trail, Enduro and e-bikes.
Progressión - 21%
Anti-Squat
The Reason presents an optimized and balanced anti-squat curve, firm when you pedal, sensitive when the terrain requires it. With values from 108 % to 104 % in the SAG, it eliminates bobbing while pedaling and maintains a stable and efficient suspension during climbs. Its progressive descent up to 65 % improves traction on large compressions, achieving a perfect balance between performance and sensitivity.
Anti Drive
The Reason features a progressive anti-dive curve around 55 %, which allows maintaining control during intense braking without excessively stiffening the front suspension. This value falls 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 crucial.
Kick-Back
The Reason presents a progressive Kick-Back curve with a moderate value of up to −20°, perfectly balanced for a trail/enduro e-bike. This figure is within the ideal range, minimizing interference in technical pedaling without compromising sensitivity on descents. The result is an active, predictable suspension with excellent traction, ideal for maximizing motor assistance on any terrain.

Smart touchscreen display
The Reason features the 2” OLED touchscreen of the Avinox system, fully integrated into the frame. This advanced interface allows you to manage the drive unit and connect to the app. With automatic brightness up to 800 nits, it is readable in any condition and resistant to water, dust, and use with wet fingers.

Smart Assistance

Eco
Designed to maximize range on long rides, Eco mode provides smooth acceleration from the start and reduced assistance, ideal for riding on flat surfaces while optimizing energy consumption.

Auto
Optimized to adapt dynamically to different conditions, Auto mode uses an advanced sensor fusion system that regulates assistance automatically and continuously, based on the effort applied to the pedals. Ideal for long rides and constantly changing terrain.

Trail
Perfect for varied and technical terrain, Trail mode provides intermediate and progressive assistance, offering more support where needed without sacrificing control. Designed to tackle irregular sections with a balance between power and efficiency.

Turbo
Specifically designed for demanding climbs, Turbo mode delivers immediate acceleration combined with the highest level of assistance, allowing you to overcome obstacles and steep slopes with ease and speed.

Boost
Boost mode activates an extreme burst of up to 150 Nm of torque and 1300 W of maximum power for 30 seconds. Ideal for critical situations where extra power is needed, such as steep climbs or complex obstacles on the trail.
