My Rad City 5 plus battery after 2 months not used indicated 4 bars on battery led. After charging overnight, battery charger indicated charged but led's on battery still showed 4 bars.  I assumed it had not charged. It most likely was fully charged. Rad help desk advised to run battery down to 1 bar and then charge overnight.  I lifted rear wheel of ground (rope over garage rafter) and rapped old inner tube around throttle and let'r go full speed.  It took 3 hrs to run down to 1 bar.  So I'm thinking it was fully charged and led's on battery not showing true. I didn't think to check the UI display at that time. Then after charging overnight once more it still showed the same 1 bar. Rad help desk said to do that cycle 2 more times and indicated a repair service might be able to replace a fuse. Instead I put on bike and this time checked display which showed fully charged.  You Tube has a video on replacing fuse.  It was easy to pop off the cover, then 4 torx size 10 screws. Hard part getting to the 10 amp auto fuse buried about 1/2 inch under blue tape.  Indeed it was blown out. After changing that out, charged overnight and now battery led's completely out.  Put on bike and UI display showed fully charged.  Wife test rode, everything works fine and she says can live without battery led's better than without $600.00.  If Rad had designed a convenient port for this simple fuse fix it could avoid a great deal of complaints and risk of tearing into an out of warranty batteries. No idea why LED's on battery now not working at all.

My wife does not want to switch gears unless absolutely necessary.  What gear should she be in for flat/level city streets and which pedal assist would go best with that gear?... please... thanks. .. Just got our bikes today.  Same question for me and my Radrover 6 plus.
