I do something that's probably a bit silly with my bike. I have the Trek EXe as well, and I tune the Eco mode really low. I've been riding for 25 years and the whole reason I got an e-bike was due to a back injury I got in the last couple of years. On my trail bike, I was only able to ride 20-30 mins before my back injury started screaming at me. On the e-bike, I can ride for a couple of hours before this happens. So, what I decided to do was tune Eco mode down to something that resembles how it felt to ride a very light weight XC bike. I do this so I can keep my legs and cardio somewhat strong. I found that when I first got the bike and rode in Mid mode, I lost some of my fitness over time. I keep playing with these settings to see if I can make it feel more "normal" but right now I have Eco at 78W Power, 40% Assist. I tried doing something like 300W power at 25% Assist, but on flats, the bike did too much of the work for me. I ride in this setting until my back starts to feel fatigued or angry and then I bump up to Mid, which is tuned at 195W and 95% assist. Riding in Mid is a lot of fun and takes a lot of the stress off of my lower back on steep climbs. Then I have High set at absolute Max. I have honestly only ever used High a few times since I have owned the bike, and it's usually when I'm overly fatigued throughout my entire body, and I need to get up that really steep technical climb to make it back home. Sometimes my back isn't experiencing as much pain, and I can ride in Eco the entire trip. This allows me to only burn 20% of my battery on a 1.5 hour ride. So, on a really good day, I can get ~5 hours of ride time. When I throw Mid into my rides more, I get around 3-4 hours of ride time. This allows me to get a lot of great heart pounding exercise in. When I need it, I'll bump up assist with Mid mode and finish out the ride. Either way, I can stay on the trails as long as I used to now, and that's what made me excited about this e-bike.
