Mechanical shifting at its best.
This 12-speed E-MTB mechanical drivetrain system is designed to deliver consistent, precise shifting performance under the demanding conditions of high-torque electric mountain biking.

The system features a reinforced full-mount rear derailleur structure, providing exceptional rigidity and impact resistance for off-road and E-MTB use. To support long-term serviceability, the derailleur is engineered with replaceable structural elements, including outer and inner linkage components, protective skid elements, and a tool-free serviceable cage assembly—making it an ideal solution for workshops and aftermarket replacement.

At the core of the drivetrain is a forged aluminum E-MTB crankset, optimized for strength and durability, paired with a drive-unit–specific 12-speed chainring designed to handle continuous motor-assisted torque while maintaining reliable chain retention.

Consistent shifting under load is essential for E-MTB riding. This groupset achieves dependable gear changes through a wide-range 12-speed cassette with optimized tooth profiling, combined with a precision single-click mechanical shifter that ensures accurate actuation even during steep climbs and high-load conditions.

Installation and setup are designed to be straightforward and mechanic-friendly. The simplified adjustment process minimizes setup time and reduces tuning complexity, allowing for fast, reliable installation in both professional workshops and DIY environments.

Built for long-distance riding, challenging terrain, and high-torque mid-drive E-MTB systems, this mechanical 12-speed drivetrain groupset offers a durable, serviceable, and dependable solution for aftermarket and replacement applications.
