I worked on the bike trying to find where the clicking was coming from: I put a few drops of oil on seat clamps, seat post clamp, rear wheel where spokes crossed, check cassette, check hanger bolts, check jockey wheels and bolts, rear wheel for looseness, checked crank for looseness and play, checked pedals, check chainrings found one missing bolt checked my stash and found one to replace missing bolt, checked front wheel and headset. Everything was good except missing bolt... I think I fixed the issue. Put batteries in for lights and power meter pedals, install bike computer cameras and radar, installed helmet lights, got dressed and ready to ride, off I go thinking everything was good! Bike felt great, smooth and quiet I'm feel good about everything, getting out much later than I was hoping but I'm out riding and no clicking but it never clicked this early on the ride, normally it takes at least 4 miles. It was cold luckily I put on arm and leg warmers. 1.5 miles into the ride, the clicking stated up I stop 5o check everything quickly and found no issues, all chainring bolts are there and everything tight. I start back up now I decided to cut the ride shorter than I was planning. The clicking was even louder and more frequent, I was a little depressed that nothing I did fixed the issue. I'm back thinking it had something to do with the Di2 that goes around the Bottom Bracket. The only way I am able to get the clicking to stop is to back pedal. It works for a short time then comes back. The ride itself was going great and enjoyable. I get near the midpoint and the road was being worked on. So I turned around short of mid point. I get to the darkest spot about 10 or 12 miles to get back home I get a flat in the rear tire. I pull over checked the rear tire before removing tire and find staple in the tire, removed it and the tire, replaced tube and put everything back together. Off I go... not letting anything get me down on a very nice night ride. I get home take everything off bike, put everything on charger, heated up my dinner. Turn on computer and the blue screen of death comes up! Still feeling good about the ride and on the post ride high, I wasn't going to let this get me down, 2 hrs later I get the computer back up and running! Not really sure what happened to cause the computer issues, Running some diagnostics to see if the problem still exists. Seems like everything is back to normal. What a day full of adventures, life is never boring! Be safe out there, enjoy your ride...
