The first e-bike I saw that wasn't hideous was this blue iZip bike.
Then I saw these Kilowatt bikes. I thought they looked pretty cool for being electric assist. I wish that I had gotten a chance to take one for a ride, but I didn't come to their booth until the end of the last day of Interbike. I love that one of the frames is a mixte style. I love the argyle detail and the colors. The awesome iridescent purple/blue color was apparently a mistake gone terribly right and now is a production color. It looks really nice in person.
