This post is specifically directed to the distaff side.

Bike riding is fun, but it's even more fun with your best friend. The bright and shining center of my universe and I are going shopping for a new bike for her. The key factors are: road bike suitable to a woman of substance that will enable her to feel comfortable and in control. The goal, apart from the obvious one of having fun, is to build up endurance while burning calories. Are there any bikes you would recommend we particular seek out for test drives?

Much obliged!
