I keep one inside of the neoprene chain guard.

I have the same brakes on my City 5+ and they were very noisy/grindy like you described. The pads wore out after the first 500 miles (lots of steep hills around here). The noise is completely gone with my new brake pads. The stopping feels really smooth. These are what I put on: https://amzn.to/3NpaMwm

Assuming you have the Nutt hydraulic brakes, these will work:

I've been using these with my RadCity 5plus and they have been working great.

Mine worked fine out of the box and I?m very happy with it. As usual, those of us who don?t have any issues don?t post about that [emoji6].

I have the same bike and my rear brakes work well. There's probably just something wrong with yours. Hopefully they get it figured out.

If you use silicone to seal the battery, I would recommend avoiding any silicone with acetic acid (it smells like vinegar). Acetic acid can corrode the electronics in the battery pack. Permatex Ultra Black gasket maker does not have acetic acid and is available at most automotive supply stores.

Thank you for this info, Dick! My wife went on her first ride today and tried to remove the battery after the ride by accidentally putting the key in the charing port. It made a spark and the fuse was blown. I was able to remove the one end cap and cut just in front of the fuse and replace it. I put some Permatex Ultra Black (chosen because it is acetal acid-free) over the opening to seal it back up. It appears to be charging now. RadPower wasn't at all sympathetic about this and just told me it wasn't covered under warranty. At least there is a way to save these.
