Lightness that adapts to your style

Designed to offer the perfect balance between low weight and high performance. Choose between the solidity of aluminum or the responsive lightness of carbon. Adjustable geometry and optimized kinematics ensure agility, control, and efficiency on all types of terrain. Thanks to DJI's Avinox system, you can count on powerful and smooth assistance, ideal for both challenging climbs and technical descents. A lightweight, precise e-bike suitable for every cyclist.

Precise design and kinematics
The REASON revolutionizes the world of e-bikes with a high-performance, lightweight frame with exceptional kinematics. It absorbs vibrations without losing responsiveness and offers agility, control, and precision at all times. Its integrated, clean, and streamlined design looks like a muscle bike: no one would guess it's electric, even up close.

Adjustable geometry
A Flip Chip system allows you to quickly and easily adjust the frame geometry. Change the steering and rear triangle angles 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.

Smart touchscreen
The REASON features the DJI Avinox system's 2" OLED touchscreen, 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 all conditions and resistant to water, dust, and wet fingers.
