SpeedFun Furious Evo easy+ for Bosch Performance Line PX Smart System – Rim Magnet

What is the SpeedFun Furious Evo tuning for Bosch Performance Line PX (BDU347x) and Performance Line (BDU346x) Smart System – Rim Magnet?

Compatible with the latest Bosch Drive Unit firmware version 19.54.0 that was released on May 4, 2026 as part of the major Performance Update 2.0 for the Bosch eBike Smart System.

The SpeedFun Furious Evo tuning device electronically manipulates the rotational speed signal from the rear wheel and constantly feeds the motor a perceived speed below 25 km/h. This allows the motor to remain fully active, delivering assistance at significantly higher real-world speeds. The maximum achievable speed is therefore determined by the combined power of the motor and your own pedaling effort (info).

When the tuning device is active the display shows the accurate speed up to approximately 20 km/h. Beyond this threshold, it displays a manipulated speed that is always kept below 25 km/h.

This speed-unlock device is compatible exclusively with Bosch Performance Line PX (BDU347x) and Bosch Performance Line (BDU346x) equipped with the Rim Magnet (magnet located on the valve/rim). It works regardless of the display or controller unit fitted on the bike.

SpeedFun Furious Evo is supplied pre-configured and ready for immediate use. It can be activated and deactivated at any time and it retains the last setting even after the ebike is switched off.
Installation is straightforward thanks to the use of compatible connectors.
