If you own an e-bike equipped with the top-of-the-line Yamaha PW-X4 motor , you can now finally free it from the speed limit with our new, custom-developed chip. This means you get maximum power support no matter how fast you're cruising through the terrain.
The new chips are available here:
- Specialized 3.1: Easier installation thanks to original connectors

These chips are now supplied with original connectors that 100% comply with factory standards. Installation becomes a matter of " Plug & Play" - everything fits together exactly on the first click, which ensures maximum connection reliability even in difficult off-road conditions.

- Assurance for Bosch owners: We are ready for update 20.27 (07/2026)
The most important topic of the last few days is clearly the release of a new software update for Bosch Smart System engines (version 20.27 from July 2026). This update promises a noticeable improvement in torque, but understandably raised questions about the functionality of the existing tuning chips.
We can reassure you. Our development department has thoroughly tested the situation and the result is perfect: All our chips for Bosch Smart System and Bosch Smart System + RIM are STILL FULLY COMPATIBLE with the latest update. So you can update your engine software with peace of mind and continue to enjoy full performance without speed limits.
