The classic hubs are better than the Hydra hubs but I still wouldn’t use I9 anything on an e-bike. I’ve broken a few axles on my hydras and I’m not even a big guy, seems to be a pretty common thing with them.Have a set of I9’s on my meat powered bike, had to buy a ti axle because I broke 3 rear axles in alloy. If you plan on running I9’s on a e bike, plan on an axle replacement.
Weird, haven’t heard of that. I did hear of an issue with the Hydra hub that they rectified that left a bad taste in many people’s mouths. Forgot exactly what it was off the top of my head, something with the bearings I think? But it was a common issue and they did address it with a manufacturing change that seems to have improved them from what I’ve heard.The classic hubs are better than the Hydra hubs but I still wouldn’t use I9 anything on an e-bike.
