Bosch 4th Gen Performance Line Ebike Motor Updates: 85Nm Torque, eMTB Refined, Extended Boost!

Bosch announced several updates for their 4th generation Performance Line electric bike motors this past week. These updates will be available through dealers in Summer 2020 free for existing owners (though a dealer may charge you to install the new software). I’ve listed a few of the updates below, and welcome your feedback!

– This update only applies to 4th generation Performance Line CX, Performance Line Speed, Cargo Line, and Cargo Line Speed. You can tell these motors by the labeling on their case, the full sized chainrings, and the ISIS splined spindles vs. BNI (Bosch Narrow Interface) spindles.
– Peak torque output will rise from 75 newton meters to 85nm, increasing starting and climbing power for riders.
– eMTB mode will be refined and now automatically include Extended Boost (which keeps the motor going between pedal strokes, to help maintain momentum and balance).
– In general, the motors should offer faster and more powerful acceleration, especially at lower cadence.
