I bought a pair of Schwinn Sidewinders from Wally world for us to ride with our kids. Other then a little heavy I really felt they were ok for the $129 I gave for each of them. Shimano components...cheap ones but they worked and have not given any trouble. Worked a lot better then my old P8 Peugeot. I commuted on it for a few weeks before I found that the fact that it was too small was killing my knees. Sold it to a work cohort that it fit better. He still riding it happily and had no problems with it.

Wife still has hers and likes it for our MUP rides. She has no intention of getting on the roads with me so most of its miles are on the trainer.
