The Motor.Gearbox.Unit E1.12 and E1.12S provide 12 gears and are characterized by

equally fine-tuned gear jumps and a whopping gear range of 600%. They are the flagship

models of the Pinion E-Line and will always provide the perfect gear no matter if

you’re on the road, in the backcountry or anywhere in between. Rider and E-System thus

always work in the optimal speed and cadence range and are always in the sweet spot of

efficiency and ergonomics. 

The 9-speed versions of the MGU provide an amazing entry into the world of Pinion 

MGU-Technology. The steps between gears may be slightly larger than the 

12-speed-versions but the gear range of almost 570% blows common derailleur setups 

out of the water, nevertheless.


The motor-gearbox units with the suffix “S” at the end provide assistance up to a speed

of 45 km/h. The maximum motor power has also been increased from 600 watts to

800 watts in order to be able to reach the speed of 45 km/h easily.
