So as an update to my Domane HP+ experience, the bike now has 8432 miles on it, this year I have climbed almost 500K feet. The bike has been essentially flawless in operation. I indeed did have shifting cable failure and some early on battery sitting issues. I did purchase a second battery full battery, not the black snap on one, but a full body one to take if I am going to be on longer trips on my rear rack. I rarely take two batteries unless I know there will be big elevations and distances (like 8000 feet and 100 miles or more).
With regards to battery, the original battery has lost some of its power, I does go quickly from 97 % (it wont charge to 100% now) to around 89 percent. Bosch has said this in normal over the number of charge cycles that it has been through. I would like to find out if cells can be replaced, but Trek/Bosch apparently don't do that type of work. So there we are. From a distance perspective I can still get about 50 miles or so out the battery with eco, but its dependent on terrain, which around me is not flat. My rides are usually 1.5-2.5 hours and an average speed about 18 mph. I often ride with the bike off (about 70 percent of the time). A ride from my house up and over mountains and back again (usually around 5600 feet) in around 45 miles results in me using about 70 -75% of the power. just to put things in perspective.
Now for a biggie, about 3 weeks ago I had Trek install a goatlink / wolftooth with a new cassette for improved hill climbing ability. WOW what a difference. 11-46T now sits on the bike. The Domane is now so much more efficient for me to ride, which means improved battery performance. This is pretty cheap swap of parts about 200 dollars with installation and I am able to climb stuff where I had to use eco before and now its not problem. I live in Southern California and go up and though the Santa Monica Mts all the time. For me this is a great update and wish I had learned about it earlier. With that in mind, If you're not concerned about speed, one could consider a smaller front chain ring too.
To sum up as the Domane HP+ continues to be a joy to ride and I have no reservations on recommending the bike for fitness, recreational riding or commuting. Its a great piece of kit.
