I Raced an Italian e-MTB Enduro With Bosch's Free Upgrade

Jennifer Miller · 2026-06-10

Bosch just dropped a free upgrade for their CX and CXR Gen 5 motors. It's called Performance Upgrade 2.0, and it's available to anyone with a Bosch-powered e-bike. So naturally, we updated our bike, hopped on a plane, and headed straight to Bike Festival Riva on Lake Garda, Italy. Our mission? Test the new features in the most honest way possible: by racing the Bosch eMTB Challenge blind. ### What Is Performance Upgrade 2.0? This isn't just a tweak. Bosch claims the upgrade delivers smoother power delivery, better torque management, and improved battery efficiency. Think of it like tuning your car's engine without spending a dime. The download is free, but you'll need to visit a Bosch dealer or use the eBike Flow app to install it. Once it's on, your bike feels different. The pedal assist kicks in more naturally, especially when you're climbing steep, loose terrain. ### The Race: Blind Enduro Style The Bosch eMTB Challenge is an e-bike enduro with six stages for amateurs and seven for pros. What makes it unique? It's a blind race. You don't get to pre-ride the stages. You show up, get a map, and race each stage on sight. That's nerve-wracking and thrilling at the same time. You have to trust your bike and your instincts. And with the new upgrade, you have to trust the motor too. ### How the Upgrade Felt on the Trail Racing blind on an unfamiliar course is tough. But the upgrade helped in ways I didn't expect. - **Climbing:** The motor now delivers power more gradually. On steep, rocky climbs, I didn't feel that sudden surge that can throw you off balance. Instead, it felt like a strong, steady push from behind. - **Descending:** The freewheel resistance is lower. That means when you stop pedaling, the motor doesn't drag as much. You coast faster, which is a big deal in enduro racing where every second counts. - **Battery Management:** I finished the race with more battery left than I expected. The upgrade seems to optimize power use without sacrificing performance. ### The Verdict After Racing Blind Would I recommend the upgrade? Absolutely. It's free, it's easy to install, and it genuinely improves the riding experience. But here's the thing: it's not a magic bullet. You still need to be a good rider. The upgrade just makes a good rider better. If you race enduro or even just ride technical trails, you'll notice the difference. ### What About the Event Itself? Bike Festival Riva is a bucket-list event. The trails around Lake Garda are stunning, with views of the lake and the surrounding mountains. The atmosphere is electric, with riders from all over Europe. And the Bosch eMTB Challenge is well-organized, with clear stage markings and plenty of support. If you get a chance to race it, do it. Just make sure you download the upgrade first. ### Final Thoughts Bosch's Performance Upgrade 2.0 is a smart move. It rewards loyal customers with a tangible improvement without asking for more money. For anyone serious about e-MTB racing, this is a no-brainer. And for the rest of us? It's a great excuse to get out and ride.
