New-to-me RadRunner Plus

[EmJay]

Hi folks,
I found an amazing deal on a 2020 RadRunner Plus with 300 miles on it a couple months ago.

This is my first E-bike and I LOVE IT!! Already I put on an additional 1,000 miles. I live on a steep hill with a 1/2 mile gravel driveway, and this bike has never let me down. 

Last week the bike developed a growling noise for a few seconds on acceleration. Either the motor controller or the motor has an intermittent issue. This is my daily driver 9 miles each way, so reliability is really important to me.

I have plenty of technical ability and I'm willing to upgrade. Any suggestions?

Thanks a bunch!!
EmJay
