My wife and I just decided to get into bikes for the first time since we were kids. After doing some research and lokking at a friend's Trek Navigator 300, I decided to get a Nav. 200 because of its comfort, stability, and good quality for the price. My wife insisted on a Walmart Schwinn Aluminum Comp. She was OK with the bike till she rode mine and then realized the problems with stability and steering of the Schwinn. So it looks like a Nav. 200 ladies for her. Is this a good choice considering we want to do easy riding on paved and hard packed dirt roads?
