The C1.12 gearbox is the shifting system for everyday, leisure and touring riders. 12 finely stepped gears offer an outstanding gear ratio range and unique shifting comfort. With a 600 % overall gear range, the C1.12 gearbox easily outclasses modern derailleur drivetrains.

Reliable, clean &
low maintenance

The Pinion gearbox is extremely low maintenance and virtually wear-free. Due to the sealed housing design, dirt can’t get into the system. Frequent drivetrain cleaning and lubrication is a thing of the past!

In our 4 categories you will find E-Trekking bikes, E-Mountain bikes, Speed-Pedelecs, light E-Bikes, and E-Cargo bikes from innovative manufacturers – all with Pinion gearboxes and hub-motors.

Protected shifting mechanisms

Pinion stands for reliable and durable drivetrains – under all conditions. The magnesium housing of the C-line is treated with a durable, anthracite metallic coloured powder coating. For additional peace of mind, a protective film protects the gearbox from stone chips.

Lighter centre of mass

The compact magnesium housing is 33 % lighter than aluminum. Sophisticated, high-precision manufacturing processes allow the use of an ultra-light “Made in Germany” magnesium alloy.

Design of the gearbox types

Common to all gearboxes is the spur gearing consisting of two sub-units connected in sequence. The individual gear ratios are derived by matching the two sub-units with various cog pairings.

The C1.12 gearbox is built using a 4-gear unit mated to a 3-gear unit – a 4 x 3 gearing type. The C1.9 is a 3 x 3 type.

The C1.12 gearbox is the shifting system for everyday, leisure and touring riders. 12 finely stepped gears offer an outstanding gear ratio range and unique shifting comfort.
E-bike and enduro riders love the pure efficiency of the 9-speed gearbox. The C1.9 is optimized for applications where larger gear steps and efficient shifting are a priority.
The C1.6 is our lightest gearbox type and is used in urban e-bikes, E-cargo bikes and in commercial fleet and rental operations.
