High Load Capacity and Torque Resistance
Cargo bikes often transport several hundred kilograms in total weight. This generates enormous forces — especially when starting on a hill or riding fully loaded. A suitable drivetrain must therefore:

• withstand high torque loads,
• ensure smooth power transfer,
• and operate with minimal wear even under continuous stress.

Conventional derailleur systems quickly reach their limits here, particularly when combined with powerful e-drive motors.

Low Maintenance and Long Service Life
Anyone who uses a cargo bike daily knows: maintenance costs time and money.
A sealed hub gear system is far better protected than a derailleur — no dirt, no rust, no constant adjustments. This results in longer service life and reduced service intervals — a real advantage in commercial use or everyday riding.

Reliability — Even Under Heavy Loads
For heavily loaded cargo bikes, it is essential that the drivetrain works reliably and robustly. The system must function even when the bike is under tension, supported by a strong motor, or subjected to frequent stop-and-go situations.

The 3X3 NINE hub gear was developed specifically for these requirements. It combines German engineering with real-world durability — ideal for cargo bikes used privately or professionally.

Technical Advantages at a Glance

• High torque capacity: Up to 250 Nm input torque — perfect for powerful e-drives and heavy loads.
• 9 true gears: Optimally spaced gearing for smooth riding, whether empty or fully loaded.
• Low maintenance: Fully sealed system protected from dirt, moisture, and salt.
• Mechanically robust: Engineered for long service life and maximum durability.
• Made in Germany: Quality built for longevity and sustainability.

Perfect for E-Cargo Bikes

With its extreme torque resistance, the 3X3 NINE pairs perfectly with modern mid-drive motors. It transfers motor power efficiently and without loss — ensuring a controlled, powerful riding experience in all conditions.
