First shift, then reinforce! In the pedelec technology everything depends on the correct order: The combination of rear engine and Pinion gearbox ensures harmonious handling and is gentle on the drive. Compared to the mid-engine system, the powertrain is exposed to much lower forces. This is the only way to enjoy e-biking in the long term. Designed for high loads and a long service life, the C1.6 is a faithful companion. Low-wear, reliable, intuitive.

C1.6 Ratio Calculator

The Pinion gearbox calculator helps you to choose the ideal gearbox tuning. The internal gear ratio for each gear of all types of gearboxes is already defined in our calculator. The entire spectrum of a Pinion transmission can be shifted to fast or slow with the secondary ratio to the rear wheel. A 1:1 tuning is also possible by using sprockets of the same size or toothed belt pulleys.

Calculator is Available in only Desktop Mode

(Number of teeth chainring gearbox)
(Number of teeth sprocket rear wheel hub)
(Wheel circumference in mm)
(in mm)

Additional ground clearance compared to a derailleur gear system with a chainring with 44 teeth

The size ratio, or the ratio of the number of teeth between chainring and rear sprocket is called ratio. Together with the circumference of the wheel the unfolding can be calculated. The unfolding is the distance in meters or centimeters travelled by a bicycle with one crank rotation.

REAL GEARS
Real gears refer to the gear steps of a bicycle transmission that can be optimally used. In derailleur gears, the skewed running of the chain leads to significant losses of efficiency. In addition, when there are two or three front sprockets there will be redundant, i.e. equivalent, gears. A 3×10 derailleur transmission, for example, actually only offers 14 or 15 real gears from this perspective.
