Our goal: to make biking easier. That’s why we’ve developed a gear hub that works perfectly and needs no maintenance, leaving you free to simply enjoy riding your bike spontaneously and independently.

Ease of use Just ride

You want to ride your bike and not worry about cleaning sprockets and lubricating and adjusting gears. The NINE offers you reliable performance without any hassle so that you can do just that, whether you are mountain biking, riding to work, or taking on the urban jungle—and whether you are riding an e-bike or conventional bike. That’s what we mean by “ease of use.”

No more maintenance — with the 3X3 NINE in your rear wheel

9-speed gear hub


A gearshift that works the way you want it to—allowing you to change gears whenever you want, whether you are stationary or halfway up a hill. And since there is no derailleur, there is nothing to bend, just a smooth shift every time. Everything works reliably, so all you need to do is ride.


Strong enough to handle the power of a large electric motor, flexible enough to perform in a mountain bike. And, if you care about the technical details, the maximum input torque is 250 Nm and the total gear ratio is 554%.


Yes, you read that right: the NINE is completely maintenance-free. That means you can forget about oil changes and time-consuming servicing and get on with planning your next biking adventure. Even the gears are calibrated for life.

Low wear

The absence of a sprocket set means your chain always runs parallel to the frame, guaranteeing a long life span, even when used with a powerful electric motor. This saves you money and protects the environment. Only a belt drive can improve your eco-balance even more and, of course, the NINE can accommodate this too.

Technical details 3X3 NINE

Who wants to spend their time maintaining their bike? No one! That’s why we’ve developed a gear hub that makes cycling even easier and more intuitive. The NINE needs little maintenance and works both when stationary and under load. Its planetary gearbox is protected from the environment and operates with the same precision after thousands of kilometers as it did on its first day of use. You can use it with either a chain or a belt drive and it is robust enough to easily handle even powerful electric motors. You may not be able to tell from the outside, but the housing conceals the finest technology available, so all you need to do is ride.
