Tapered Head Tube
Precision Steering Control. Engineered for high-speed eMTB riding, the oversized tapered head tube delivers maximum front-end stiffness. It handles heavy suspension fork loads with zero flex, ensuring pinpoint steering accuracy on rugged trails.
Integrated Mid-Drive Motor Mount
Built for Massive Torque. This precision-cast, heavy-duty motor bracket ensures flawless alignment for mainstream mid-drive systems. It securely anchors the motor, efficiently transfers high-torque power, and protects the drive unit from lower trail impacts.
Optimized Suspension Linkage
Unmatched Trail Traction. Featuring a robust rocker arm and high-strength pivots, this active rear suspension setup efficiently absorbs big drops and technical terrain. It keeps your rear tire firmly planted for maximum grip and a plush ride.
Concealed Battery Downtube
Sleek & Perfectly Balanced. The massive, fully integrated downtube securely houses high-capacity e-bike batteries. This seamless design protects power cells from water and debris while lowering the bike’s center of gravity for superior cornering stability.
Maximum Tire Clearance
Grip Without Limits. The widened rear triangle design effortlessly accommodates plus-size eMTB tires. Enjoy superior mud shedding capabilities and the freedom to run aggressive, high-volume rubber for ultimate off-road traction.
