Precise design and kinematics
The REASON is redefining the e-bike category with a high-performance frame that´s both lightweight and engineered with unbeatable kinematics. It absorbs vibrations without sacrificing responsiveness and delivers agility, control and precision at all times. Its sleek, integrated design looks just like a muscular bike - no one would guess it's electric, not even up close.
Adjustable geometry
With a Flip Chip system that allows you to adjust the frame’s geometry quick and easy. Modify the head tube and rear triangle angles to suit your riding style or terrain type. One frame, four possible configurations. Maximum versatility for riders who want it all.
 
 
Kinematics ready for action / The evidence
leverage ratio
Leverage Ratio
The REASON features a progressive kinematic design with a 21% leverage ratio, ensuring a sensitive suspension at the beginning of the travel that becomes progressively firmer. This behavior improves traction, comfort, and avoids bottom-outs on big hits or jumps. It also allows fine-tuning via volume spacers or tokens in the shock, adapting to different riding styles. A smooth, balanced, and controlled curve, ideal for Trail, Enduro, and e-bikes.

PROGRESSION

 
21%
anti-squat
Anti-Squat
The REASON has an optimized and balanced anti-squat curve—firm when pedaling, responsive when the terrain demands it. With SAG values from 108% to 104%, it eliminates pedal bob and keeps the suspension efficient and stable on climbs. The progressive drop to 65% improves traction in large compressions, delivering the perfect balance between performance and sensitivity.

EFFICIENCY

 
108%
anti rise
Anti-Dive
The REASON features a progressive anti-dive curve around 55%, maintaining control under hard braking without excessively stiffening the fork. This value falls within the optimal range (50–70%) for Trail and Enduro, ensuring a stable ride, active fork, and natural feel in technical terrain.

ANTI-DIVE

 
60%
anti rise
Kick-Back
The REASON features a progressively tuned kickback 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 system with excellent traction—ideal for maximizing motor assistance across all types of terrain
