Bosch Performance Upgrade 2.0: Racing an Italian e-MTB Enduro

James Moore · 2026-06-10

Bosch just dropped the Performance Upgrade 2.0 for its CX and CXR Gen 5 motors. It's a free download for anyone with a Bosch-powered e-bike, so we grabbed the update, hopped on our bike, and headed straight to Bike Festival Riva on Italy's stunning Lake Garda. Our mission? Test the new features and race the Bosch eMTB Challenge blind. ### What's New in Performance Upgrade 2.0? The upgrade tweaks the motor's behavior to feel more natural and responsive. You get smoother power delivery, especially at low speeds, and better traction on loose terrain. It's like the bike reads your mind—less lag when you punch the throttle, more control when you're picking through rock gardens. Bosch says it's all about improving the ride feel, and honestly, it delivers. ### The Bosch eMTB Challenge: A Blind Enduro The Bosch eMTB Challenge is an e-bike enduro with six stages (seven for pros). The twist? It's a blind race. You don't pre-ride the stages. You show up, get a map, and race. That means you're reading the trail on the fly, making split-second decisions about lines and speed. It's intense, but it's also a pure test of skill and adaptability. ### Racing at Lake Garda Lake Garda is a mountain biker's paradise. The trails are steep, rocky, and technical—some sections hit 40-degree gradients. Temperatures hovered around 75°F, and the elevation topped out at 3,500 feet. We covered about 15 miles over the six stages, with each run dropping around 1,000 feet. The new motor upgrade shined on the climbs, letting us save energy for the descents. - **Stage 1**: A fast, flowy start through pine forests. - **Stage 2**: Tight switchbacks with loose gravel. - **Stage 3**: A rocky chute that demanded precise line choice. - **Stage 4**: A root-infested section that tested suspension. - **Stage 5**: A steep, exposed ridge with stunning lake views. - **Stage 6**: A technical descent with drops and berms. ### How the Upgrade Performed On the trail, the upgrade felt like a different motor. The power came on smoother, and the bike felt more planted. In the blind race, that predictability was huge. You don't have time to think—you just react. The upgrade made the bike feel like an extension of your body. It's not just a gimmick; it's a meaningful improvement. ### Final Thoughts If you own a Bosch CX or CXR Gen 5 motor, download the upgrade. It's free, and it transforms the ride. The Bosch eMTB Challenge was a blast, and the upgrade gave us an edge. For $0, you can't beat that.
