Upgraded Bosch Motor: Racing Blind at an Italian e-MTB Enduro

Jennifer Miller · 2026-06-10

Bosch just dropped the Performance Upgrade 2.0 for their CX and CXR Gen 5 motors. And guess what? It's a free download for anyone with a Bosch-powered e-bike. So we did what any sensible rider would do: we updated our bike, packed our gear, and headed straight to Bike Festival Riva on the stunning Lake Garda. Our mission? Test the new features and race the Bosch eMTB Challenge, an e-bike enduro that throws in blind racing for good measure. ### What's the Bosch eMTB Challenge? The Bosch eMTB Challenge is no ordinary race. It's an e-bike enduro with six stages for most riders, and seven for the pros. The twist? Blind racing. You don't get to pre-ride the stages. You show up, see the course for the first time, and go all out. It's raw, it's unpredictable, and it's a true test of your skills and your bike's capabilities. ### How the Performance Upgrade 2.0 Changed the Ride After downloading the free update, we noticed some real differences right away. The motor felt smoother under hard pedaling, especially in the techy sections where you need precise control. The new software tweaks the power delivery so you don't get that sudden surge that can throw you off balance. Instead, it's more like a steady push that matches your effort. - **Better traction**: The upgrade improves how the motor responds to your pedal input, giving you more grip on loose gravel and steep climbs. - **Smoother acceleration**: No more jerky starts. The power comes on gradually, which helps in tight switchbacks. - **Longer range**: We managed to squeeze out a few extra miles on the same battery, thanks to more efficient power management. ### Racing Blind: The Real Test Racing blind is a whole different beast. You have no idea what's coming around the next corner. One minute you're flying down a fast, flowy trail, and the next you're hitting a rock garden that would make a mountain goat think twice. The upgrade helped us stay composed in those moments. The motor's response was predictable, which let us focus on line choice and body position instead of fighting the bike. ### The Bottom Line If you own a Bosch-powered e-bike, the Performance Upgrade 2.0 is a no-brainer. It's free, it's easy to install, and it genuinely improves the ride. Whether you're racing an enduro like we did or just hitting your local trails, this update makes your bike feel more capable and more fun. And if you ever get the chance to race blind, take it. It's a wild ride that will make you a better rider. > "The best part? The upgrade didn't just make the bike faster. It made it smarter." So go ahead, download the update, and see for yourself. Your next adventure might just be a free download away.
