Just got my Rad Rover 5 about a week ago and the left pedal started making an occasional but very audible ' click ' at the top of a revolution of the left crank. I watched and listened to it for another trip out.
Returning home, I unscrewed the pedal from the crank and put a tiny drop of '3-in-1' oil in the bearing crease around the pedal shaft and gave it a spin. Put the pedal back on and went on a 12 mile ride with absolutely no clicking. I'll be keeping an ear on it!
