If you are going for rides that are 10 blocks, this is exactly the kind of bike you want. It's basically the bike I've got but with larger wheels.

Sorry to be argumentative, but I think the integrated generator lights are great. "Dolling up" this hybrid is exactly what you need for shopping and utility biking. You will find such a bike easier and more comfortable for short rides and running errands. It won't take away from the fun you have with your present bike and won't replace it, either. Clearly it isn't going to go as fast.

I suggest you can be quite comfortable in such a bike for rides up to 10 or 15 miles. I think it would get frustrating after that.
