We Tested Bosch's Free e-MTB Upgrade at an Italian Enduro Race

Jennifer Miller · 2026-06-10

Bosch just dropped a free Performance Upgrade 2.0 for their CX and CXR Gen 5 motors. Anyone with a Bosch-powered e-bike can download it, so we did what any sensible rider would do: we updated our bike, packed our bags, and headed straight to Bike Festival Riva on Lake Garda. Our goal? Test the new features and race the Bosch eMTB Challenge, all while going in blind on unfamiliar trails. ### What Is the Bosch eMTB Challenge? The Bosch eMTB Challenge is an e-bike enduro with six stages for most riders and seven for pros. It's a blind race, meaning you don't get to pre-ride the stages. You just show up, pedal up, and let gravity do its thing. The format keeps things honest and rewards adaptability over local knowledge. We were nervous, but that's part of the fun. The event draws a mix of weekend warriors and seasoned racers, all running Bosch-powered bikes. The atmosphere at Riva is electric, with the Alps looming in the background and the lake shimmering in the distance. ### The Upgrade: What Changed? Bosch's Performance Upgrade 2.0 isn't a hardware swap. It's a software update that tweaks how the motor delivers power. We noticed a few key improvements right away: - Smoother power delivery: The motor feels less jerky when you stomp on the pedals. - Better torque management: Climbing steep, loose sections is more predictable. - Improved battery efficiency: We got about 10 percent more range on the same trails. The update is free, which is rare in the e-bike world. You just need a compatible bike and a smartphone with the Bosch Flow app. The whole process took about 15 minutes. ### Racing Blind in Italy Lake Garda is stunning, but the trails around Riva are no joke. They're rocky, rooty, and often steep. Going blind means you have to read the terrain on the fly. We had no idea what was around the next corner, which made every descent a puzzle. Stage one started with a rocky chute that dropped into a tight switchback. The new motor settings helped us carry speed through the rough stuff. Stage two was a flowy singletrack with a few big jumps. We cleared most of them, but one sketchy landing reminded us why suspension exists. By stage three, our legs were burning. The e-bike assist made the climbs manageable, but the descents demanded focus. We saw a few riders overshoot corners or get hung up on roots. That's the beauty of blind racing: everyone makes mistakes. ### Key Takeaways From the Event After six stages and a lot of sweat, here's what we learned: - The upgrade is worth it: The smoother power delivery made technical climbs less intimidating. - Blind racing builds skills: You learn to trust your instincts and react faster. - E-bike enduros are accessible: The motor helps you keep up with fitter riders on climbs. - Lake Garda is a must-ride destination: The trails are world-class. We finished mid-pack, which felt like a win given we'd never seen the course. The Bosch eMTB Challenge is a great test of both bike and rider. If you get the chance to race one, take it. ### Final Thoughts Bosch's Performance Upgrade 2.0 is a solid improvement for anyone who rides technical terrain. The free download makes it a no-brainer. Pair it with a race like the Bosch eMTB Challenge, and you've got a recipe for an unforgettable weekend. Our advice? Update your bike, find a blind enduro near you, and go ride. You'll come back a better rider.
