Weirdly, it was the controller.

Howdy folks, glad to be here, not so glad it's about my 3 month old bike and I can't get ahold of Rad about it.

So a couple weeks ago I started noticing a squealing  coming steadily from my rear hub at low speeds. Removed the wheel from the bike and verified that it squealed even off the bike, but it went away over 7 mph or so, so I stupidly ignored it.

Over the weeks it had gotten louder and more noticeable at higher speeds, but still couldn't be heard above 12 mph or so. At this point I filmed the behavior and emailed Rad.

The next morning I came to a stop and then the throttle just wouldn't work. It's a RadRunner, so no error codes. Checked all electrical connections and removed the rear brake just to be sure, no dice. I pedaled out off the trail and hitched a ride home.

While loading the bike, I noticed a shudder when rolling the bike backwards, leading me to believe the gears or clutch might be shot.

Does this line up with anyone else's experience with hub motor failure? I've ordered replacement planetary gears after going 2 days without a response from Rad - I would really rather not void my warranty but this is my main mode of transportation and I need it back up ASAP.

Thanks!
