A Trek Navigator. I have the 2.0, in a men's frame. It's well balanced and VERY comfortable. A friend at work, in her late 40s, went out and bought a bike last week because her old one was hurting her back. I asked what she bought - a Trek Navigator 2.0. I guess we both felt the same way, love at first sit.
She said as soon as she sat on it she knew it was "the one."
It has front fork suspension, seat suspension, and shifts very smoothly. Comfortable seat without being too big like some of the cruisers. It seems faster than some of the similar comfort bikes out there that I tried. I do, however, have a faster, more road oriented hybrid. But I do love my Navigator!
