E-bike with Pinion gearbox – the clever gearshift system
If you are looking for durability, low maintenance and riding comfort in an e-bike, you will increasingly come across one name: Pinion.
But what is behind it? And why did AureusDrive choose the Pinion C1.9 gearbox?
We explain – with advantages for everyday use, technology for discerning riders and a look at what makes Pinion so special.
What is a Pinion gearbox?
The Pinion gearbox is a fully enclosed central gearbox located directly in the bottom bracket area of the e-bike – where the crank would normally be.
Instead of a classic chain with a derailleur, a precision gearbox with multiple gears ensures smooth, consistent transmission. Gears are changed using a twist grip.
Pinion technology was originally developed for the automotive industry and has been adapted for use in bicycles by developers with Porsche experience.


Advantages of the Pinion gearbox in everyday use
+ Ultra low maintenance
No chain, no derailleur, no dirty gear components. The gear system is protected inside the housing – maintenance is reduced to almost zero.
+ Gear shifting while stationary
Traffic lights, hills, spontaneous breaks? No problem. The Pinion gear system can be shifted while stationary – comfortably and safely.
+ Smooth gear ratios
Nine precisely tuned gears with even 24.3% gear ratios – no jerking, no skipping. Ideal for commuters and long-distance riders.
+ Durability
Pinion gearboxes are considered virtually indestructible. Even after thousands of kilometres, they still shift precisely and quietly.
+ Optimal with belt drive
In combination with the maintenance-free carbon belt, this results in a particularly clean, quiet and durable e-bike system.
Why does AureusDrive rely on Pinion C1.9?
AureusDrive stands for reliable technology, easy maintenance and maximum riding comfort – that’s why we deliberately chose the Pinion C1.9 XR gearbox for our PowerDrive.
The advantages for us and our customers are obvious:
- Low maintenance: Our e-bikes should be suitable for everyday use and easy to maintain – the Pinion system requires hardly any servicing and lasts for thousands of kilometres.
- Robustness: Every component counts, especially for commuters and frequent riders. Pinion is so robustly built that it does not need to be readjusted even after years of use.
- Cleanliness & sustainability: In combination with the Gates belt drive, there is no oil, dirt or rust – a clean solution in every sense of the word.
- Riding experience: The precise, quiet gear shifting impresses beginners and technology enthusiasts alike.
- Long-term quality: We don’t design e-bikes to last 3–4 years, but for long-term use. Pinion fits perfectly with this quality standard.
AureusDrive + Pinion = Swiss engineering meets German precision.
With PowerDrive, you get a high-quality overall concept that is ideal for commuters, frequent riders or technology enthusiasts – with components you can rely on.
