Close between 4 and 5 stars, but a few things could be better. I do like it, though. I wanted somethings that felt like a regular bike, but helped me with the hilly terrain I moved to. I'm glad I waited for the 7 speed version. When I lived in "Flatlandia," I rode a 21-speed hybrid, so the feel of the gears and the general style of the bike is similar. The battery lasts practically forever, since I generally ride with the power assist at 0 or 1, and rarely need to go higher than 2 or 3 even on hills that used to be far beyond my ability. I tried the scooter option just once, to see what it felt like, but haven't ridden far that way. It's handy to have, though. The assembly process was more difficult than advertised, in part because in transit loose parts that may have once been packaged or tied together had come apart and migrated to the bottom of the box. It wasn't plain what was what. I would have appreciated better written directions, as the video was awkward to consult multiple times as we tried to figure out all the details. I would have preferred that the assist level started out at 0 or 1 when turned on, rather than 3. Or if there could be some way for the owner to change the default? 3 is way too much power for my driveway, and feels almost dangerous if I try to take off and don't remember to turn the power level down first. I also find the battery very difficult to remove and replace. I thought it might loosen up after a few tries, but it is still really difficult. I always tug and tug, find myself thinking maybe I haven't actually unlocked it, check that it is unlocked, try some more, start to despair, but finally it gives way. Putting it back on, it is also difficult to get it all the way to where it clicks and the key will turn in the lock. I realize it needs to be a strong connection, but really?
