CHASSIS

After 3 years of development and several prototypes with different geometries, kinematics, engines and carbon fibers, here is finally the most accomplished version of the ONE. We have opted for a „Mullet“ mounting, 29″ at the front for better crossing capacity and 27.5“ at the rear for optimized traction and more maneuverability. The ideal compromise to go fast! Entrusted to one of the greatest specialists in carbon fiber, the manufacture of the frame has nothing to envy to haute couture! Built from the highest performance fibers from the aerospace industry, each layer of fiber has been affixed in a specific direction to provide the required reliability while optimizing the weight and compliance we wanted to achieve on the ONE’s chassis.

In fact, most eMTB’son the market are extremely rigid, which makes them very demanding to ride and very difficult to place in winding sections. As many faults as we wanted to erase on the ONE in order to make it much more agile, more fun to fly and more accessible whatever your technical level.

KINEMATICS

To meet the demands and constraints of an EnduroeMTB, the kinematics of the ONE have been defined specifically for this practice. Even if the principle remains that of the „4 bar linkage“ used on KERN and CHARGER, this new kinematics allows to obtain different dynamic qualities and ideal for a more committed Enduropractice with powerful electric assistance.

A word about SUNN

For over 40 years, sport and performance have been at the heart of SUNN’s DNA. A pioneer of BMX and MTB in Europe since 1984, our brand remains until now on the most awarded in MTB, with over 80 World Championship titles. Mountain bike legends such as Anne-Caroline CHAUSSON, Nicolas VOUILLOZ and Cédric GRACIA have left their mark on our history, and it’s one of our proudest achievements to have accompanied them.

Passionate from the start, we use our heritage and know-how to develop a wide range of bikes that we design and assemble entirely on our own premises in France, near Nantes, at the century-old MFC factory of which we are a part. Our bikes are modern, innovative and daring, and cover all current uses: Enduro, XCO, All Mountain, mechanical or electric, BMX, Gravel, Road, Trekking and also city bikes.
