Insane upgrade for the CGO600 Pro (2025 Edition)
I shared this review on the website, but I'll share it here as well. The iSpeed is worth every penny. Unfortunately, the 2025 edition of the CGO600 Pro became much more limited than the original, making it tough to pedal past 23 km/h. With the iSpeed box, that completely changed. I actually let out an audible “Holy sh*t” when I tried it for the first time. On level 3, this thing flies up to 32 km/h if your legs can keep up. It’s most comfortable around 28 km/h due to the single-speed gear, but wow, thank you so much for making this. This will make my rides a million times more fun and comfortable. Battery life doesn't even take a big hit. In my experience, it seems to only shave about 10km off the range, which is a super reasonable tradeoff for this far superior performance. If you have this bike, this is an upgrade you won't regret!
