I also have Jones handlebars. I bought them because the swept back grips put the wrists in a egonomic position. I have a daytime strobing headlight and a Garmin radar display unit mounted on the forward bow. I love the bars (and the Garmin Radar).
I use power assist level 3 most of the time. Going uphill I need the assist. Going downhill I like to go fast. There is very little flat where I live. I use ECO on the bike path to save energy and keep my speed down. I ride for exercise.
