Unlock the speed limit of your electric bike with a Bosch E+Plus tuning dongle kit. Unleash the full speed of your ebike engine and ride it like a derestricted e-bike should be!
NOTE: Conventional tuning modules offer only limited functionality compared to today’s e-bike standards. They often rely on complicated display button sequences for activation, deactivation, and speed-limit adjustments — making them cumbersome to use. Moreover, these tunings are highly vulnerable to firmware updates, which can easily disable them.
In contrast, the EPAspeed B.Tuning series represents the next generation of e-bike tuning — fully app-controlled, firmware-resistant, and designed for effortless operation. With Bluetooth connectivity, intuitive controls, and invisible tuning functionality, EPAspeed delivers precision, reliability, and freedom unmatched by conventional solutions.

ANTI DETECTION FEATURES
The E+Plus Advanced Tuning BOSCH completes a special compensation procedure at the end of each ride that allows the tuning to remain undetectable by the Bosch anti-tuning algorithm. By allowing the countdown to complete at the end of each ride the 504 error can be avoided. The compensation begins after the bike is idle for approximately 60 seconds so once you have the tuning installed it is advised to wait and let the bike turn itself off after sitting idle.
