Pinion MGU
A revolution in terms of low maintenance. Here, a powerful motor (comparable to 85 Nm) and an electronic 9- or 12-speed gearbox merge into one housing at the bottom bracket. Derailleurs and derailleur hangers are eliminated, shifting is done electrically in a flash—even under load or at a standstill. Ideal for tour riders and E-MTBers who want "riding instead of wrenching." In combination with a carbon belt, the drivetrain is virtually wear-free and even quite a bit lighter than a regular mid-drive unit with a gearhub.

Power Characteristics
Shows how much power the motor delivers for a given rider input. The value shown is pure motor power, adjusted for input and drivetrain losses.
Input vs. Output: Pinion MGU
The Pinion MGU pushes powerfully even with relatively little own effort. The drive is close to its maximum output at a leisurely 120 watts. Significantly less than 150 watts of rider power are required for the almost 600 watts it delivers at the peak. Optimal for those who also want to be pushed up the mountain comfortably at times.
Cadence Behavior
Shows the optimal RPM range.
RPM: Pinion MGU
The Pinion MGU shows interesting behavior regarding cadence. On one hand, it is remarkable how high the power is even at low cadences between 50 and 60. On the other hand, the power increases constantly up to 120 rpm, and the rule applies: Pedaling faster leads to higher power. If you crack 125 rpm, however, the power begins to drop significantly.
Thermal Performance
Shows power output performance over 15/20 minutes under constant full load.
15 min
Due to its integrated gearbox and the resulting larger housing with more mass, the Pinion MGU has a purely physical advantage over most other mid-drive motors. This is also evident in our thermal test: We only see a slight drop in power after around 15 minutes of continuous load. Until then, the MGU is flawless.
