@siqueirah Scroll down a little further, past the Vita E+ to the Transend E+. They are very similar, from my memory the Vita has a few less teeth on the crankset (geared slightly lower), it's Class 1 (assist drops off at 20mph) and has slightly more swept back handlebars. the Transend is available as a standard or step-through frame and is a Class 3 (28mph) bike.
I've added larger platform pedals; a handlebar bag with doggie mace, hand sanitizer (don't want to mix those two up) a mask, lip balm and a disposable rain suit; a rear cargo rack: a seat bag with a thick cable lock, multi tool and a couple of small bungee cords and a water bottle cage (the Transend comes with bolts to attach a water bottle cage, but they are photoshopped out in the marketing photos for some reason). I weighed my bike once and I think it was about 52lbs with everything including a bottle of water. The battery weighs about 9-10lbs, so removing that before transporting the bike helps a lot.
If you have a chance, ride a Giant mid-drive. I rode a Trek mid-drive a Townie (Trek) hub drive and a Giant mountain bike. IMHO the Yamaha mid-drive on the Giant felt better integrated and natural, like riding a regular bike to me, I also like the minimalistic bike controls. I leave my bike in 'auto' mode and it makes riding pleasant, but I still get exercise. Hills feel flatter and I can toodle around with minimum effort on the flat bits, although I really like to move at a quicker pace. On my last ride it was late in the afternoon and I set out to ride at a quick clip to get income good cardio before it got dark. I don't have my phone with me to check the stats, but I did 10.4 miles at an average speed of 15mph and I glanced at my watch at one point and my pulse was 161, at one point I was in 6th gear keeping up with traffic in a 25mph zone, so how much exercise you get is up to you. You can crank up the assist and get to work nice and fresh or ride like you're in a spin class, it's up to you.
PS- remember, I'm in a very hilly area and every one of my rides includes riding down the loose gravel shoulder of a 2-lane highway for about a mile and I'm getting several short rides per charge totaling about 37-45 miles per charge.
