Thanks for the feedback but so far I don't see a smoking gun here. It sounds more like the luck of the draw. I was getting ready to order the upgrade from Area13 but they are currently out of stock so I got a factory replacement from Rad.
I'd like to add that we live at 6200 feet in Colorado, literally on the side of a mountain. I was reluctant for years to get an ebike but it has been a joy to not have to fight the hills.

Sounds like what I just went through. Motor just quit responding with no error codes. After many go rounds with Rad I ended up getting a new controller. Just installed it and the bike is it's old self again.

Hello all. I'm new to the group.

I just had to replace the controller on my Radrover 6 plus which only has 400 miles. I live in a very hilly mountain town.

I would like to reach out to others who have had controller failures with the question: What sort of riding do you do? I am now suspicious of my Rad for having failed and wonder if maybe it is underpowered for lots of hill climbing. The 3rd party controllers I read about sound like rockets by comparison. What are your thoughts?
