Design Philosophy
1.Integrated Power & Agility
Merge electric motor (mid-drive) and battery seamlessly into the frame, prioritizing a low center of gravity for stability on snow/sand while preserving responsive handling.
2.Carbon Fiber Innovation
Leverage Toray T700/T800 carbon fiber layering to balance strength (for heavy loads/motor torque) and lightness (sub-3kg frame weight), reducing rider fatigue.
3.Terrain-Ready Geometry
Optimize wheelbase, head tube angle, and bottom bracket height for 4.8″+ fat tires, ensuring floatation on soft surfaces and control on technical trails.
4.Modular & Durable
Internal cable routing (brake/motor) protects components; reinforced pivot points (for full suspension) and impact-resistant carbon layups withstand rugged use.
5.Aesthetic & Function
Sleek, matte-black monocoque design with clean lines, plus hidden storage for batteries/accessories, blending performance and style.
