My JBV arrived Jan 21st and I’ve been using it daily since. Things have been running pretty well up until this past weekend. I took the bike off the trainer for my first outdoor ride of the season. When I put the bike back on the trainer, I did a firmware update in the JBV app, and now I’m noticing resistance issues and I’ve had one drop out so far.
Before the firmware update, if I plugged in the trainer and started pedaling before connecting and starting a ride in Zwift, it would be easy pedaling with little to no resistance. Now it feels very hard to pedal until I actually connect and start shifting. Even when the ride begins on gear 8, there is way too much resistance, but as soon as I shift up or down it feels like the trainer wakes up and corrects the resistance, although the gearing still feels a little harder than it did prior to the update.
The drop out I experienced was near the end of a climb towards the end of the ZG25 Queen route during a race. I adjusted myself on my saddle which caused my cadence to drop for a moment, but the connection completely dropped. I was still pedaling but going nowhere. I was able to reconnect through the menu, but this was super frustrating during a race. I always connect to my iphone via bluetooth, because the one time I tried connecting straight to apple tv I lost connection. That was a few weeks ago prior to updating. I haven’t tried connecting to apple tv again since then because it’s not worth the risk of losing connection in the middle of a ride. But this recent drop out happened while connected to iphone via bluetooth, so it wasn’t a wifi issue. It’s only happened once so far, so right now I’m more concerned about the resistance issues.
