COMPACT RATIO

Carefree, fast and stylish through the city. The P1.9cr gearbox is our transmission for the modern all-round bicycle. The finely and evenly distributed nine gears are perfect for riding to work or recreational riding. Matched with a belt drive, the P1.9CR is more than just refined understatement in bicycle design. Oily chains and awkward gears are just stories from the past. Combined with a hub motor at the rear of a pedelec, the P1.9cr gearbox represents the ideal combination of two self-contained systems. The “human-transmission-motor” sequence of forces protects the drive components from overload.

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.
