Bosch 2019, 2020 & 2021  Bosch ebike Tuning & Unlock Chip

The advanced bosch ebike tuning chip offers all the same features of the standard chip – plus an app that allows you to customize the power characteristics of the drive motor, based on the type of riding you do. You can customize both the speed and the style of power delivery according to your requirements. Eplus have designed pre-set mappings from which you can choose through the app for: eco, urban, touring, enduro trial and race modes.

Device designed for Bosch 2019, 2020 & 2021 eBike in order to remove the speed limit of the engine set at 25 Km/h and consequently to maintain the assistance up to 50 Km/h, fully exploiting the performance that the engine can provide. Installation is plug and play and takes place in a few minutes without opening the engine.


The Bosch speed unlock chip completes a special compensation procedure at the end of each ride that allows the chip to remain undetectable to the Bosch tamper detection software. By allowing this 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 a chip installed the best thing to do is to simply not turn off the bike at the end of your ride and let the bike turn itself off after sitting idle. Please watch our video on the Focus Jam2 Below to see how this works.


The unlocking of the engine at 25 km/h is activated by pressing the walk button  The speedometer will always show the real speed. You can activate/deactivate the unlocker using the walk button that is the factory setting; you can change this choice using lights or reset button. For Purion, Nyon and Intuvia displays.

Compatible With Kiox Display
