Bosch update reduces drivetrain ‘dead zone,’ max power unchanged

Bosch has rolled out a free software update for its e-bike motors, significantly increasing torque to 120Nm and support levels to 600%. This enhancement aims to reduce the dreaded "dead zone" in the drivetrain, particularly noticeable at lower cadences, without altering the existing 750W maximum power output. The update, detailed by Singletracks, promises a more responsive and powerful feel for riders using compatible Bosch systems.

This development is a direct response to rider feedback regarding power delivery, especially in technical terrain where immediate, consistent torque is paramount. While the peak power remains capped by regulations, optimizing the torque curve and support percentage means riders will experience better engagement and acceleration from a standstill or at low speeds. It reflects an ongoing industry trend where software refinements are becoming as crucial as hardware innovations in enhancing e-bike performance and user experience.

Ultimately, Bosch is refining the *feel* of power rather than just the raw numbers. It’s a subtle but significant distinction, proving that sometimes, it's not about more watts, but smarter ones.
