Hi after 2 rides, yesterday my new Rad City 5 was powerless.  The battery registered full but the controller was reading 1 bar, no power at all.  I re-charged the battery, thinking although it was reading 10 bars maybe that was the issue. 

I finally unplugged and re-plugged all the connectors by the handlebars and I had power.  Although they were not loose (or did not appear to be) it worked, for now.  Im considering using electrical tape or duct tape to secure these. 

Comments are most welcome.
