I haven't ridden a 3-speed in many years--since I was thirteen, which was a long time ago. Meanwhile, I find that daily bike commuting can take a toll on the body. I've been looking at some of these 3-speeds on the road and thinking, "Now that's riding in style!" From fenders and chain guards to a handlebar that looks ergonomically friendly and offers a more upright seating posture. My question is this, how much slower are these things--especially on hills, and am I better off putting a different handlebar on an ATB with smooth tires?
