Bosch Performance Upgrade 2.0 Tested in Italian Enduro Race

Robert Wilson · 2026-06-10

Bosch just dropped the Performance Upgrade 2.0 for their CX and CXR Gen 5 motors. It's a free download for anyone with a Bosch-powered e-bike. So naturally, we grabbed our bikes, updated the software, and headed straight to Italy's Bike Festival Riva on beautiful Lake Garda. Our mission: test the new features and race the Bosch eMTB Challenge blind. ### What Is the Bosch eMTB Challenge? The Bosch eMTB Challenge is an e-bike enduro race with six stages (seven for pros). The twist? It's blind racing. You don't get to pre-ride the stages. You show up, you ride, you adapt on the fly. That makes it a true test of skill, fitness, and bike setup. ### What's New in Performance Upgrade 2.0? Bosch's free update brings several improvements to the CX and CXR Gen 5 motors: - **Smoother power delivery** – The motor feels more natural, especially when climbing technical sections. - **Better battery management** – You get more range without sacrificing performance. - **Improved responsiveness** – The motor reacts faster to pedal input, making it feel more like a traditional bike. We rode the update for two days before the race. The difference was noticeable right away. On steep, loose climbs, the power came on gradually instead of surging. That gave us more control and confidence. ### Racing Blind on Lake Garda Lake Garda is stunning. The trails around Riva del Garda are famous for their mix of rocky descents, tight switchbacks, and long climbs. Racing blind here is intense. You have to read the trail as you go, make split-second decisions, and trust your bike. Stage one was a fast, flowy descent with lots of roots. The new motor's smooth delivery helped me carry speed through corners without feeling like I was fighting the bike. Stage two was a brutal climb. The improved battery management meant I could use full power without worrying about running out of juice. By stage five, I was exhausted. But the bike kept performing. The upgrade's responsiveness made a big difference on the final descent. I could focus on line choice instead of thinking about motor lag. ### Did the Upgrade Help? Absolutely. The Performance Upgrade 2.0 isn't a gimmick. It genuinely improves the riding experience. The smoother power delivery makes technical riding easier. The better battery management gives you peace of mind on longer rides. And the improved responsiveness makes the bike feel more connected to you. If you own a Bosch-powered e-bike with a CX or CXR Gen 5 motor, go download the update. It's free, and it takes about 10 minutes. Then go hit your local trails. You'll feel the difference. ### Final Thoughts Racing blind at the Bosch eMTB Challenge was a blast. The combination of a beautiful venue, tough competition, and a bike that just works made for an unforgettable weekend. The Performance Upgrade 2.0 is a solid improvement. It's not a revolution, but it's a meaningful step forward. So if you're looking for an edge on your next e-MTB ride, this update is worth your time. And if you can make it to Lake Garda for the race next year, do it. Just don't expect to pre-ride the stages.
