These bicycles are supposed to be "one size fits most" but the two different models are different in size.

The light blue one (smooth lines, #S2753) is more like a size LARGE with frame size 19" (seat tube length 19", horizontal top tube is approx. 22 1/2"). Surprisingly it has the same geometry as the male version (also 19"). An average man is taller than an average woman - thus the men's bike should be bigger, right?

The silver/dark purple bike (sharp lines, #S2699) is a MEDIUM size with 17" frame (seat tube length 17", horizontal top tube is also approx. 22 1/2" but because of the head angle the wheels itself are about 1" closer to each other than wheels of the light blue model - beware if you have long feet). The male version of this model has 18" frame.

As for my best judgement - I would recommend the light blue bike to a woman 5'3" to 5'11" tall with inseam 28-32" and the silver/purple bike to a woman 5'0" to 5'8"tall with 26-30" inseam.

You cannot beat this bicycle for the price. It is actually fabricated in the same overseas factories that Giant builds their frames. It also is the same as the entry-level Chinese-imported Trek frame.

As for Mrs. Roberts and her problems......hate to say it, but each and every problem/symptom you described is a symptom/problem indicating a poor assembly and adjustment. You should have taken the bike(s) to a professional bicycle shop and had the mechanic there do a tune-up on your bike....all those problems would and could have been avoided completely. Chain shifting problems, chain-drop and jamming, wheel loose....all adjustment and assembley problems.

Why do I say this? I was a bike mechanic for approx. 7 years and saw many, many bicycles bought from mass-market merchandisers and over the internet with the same exact problems after the poor or unskilled assembly. Even the bikes the "real" bike shops get have to be assembled and adjusted before they are... Read more

I searched for my wife a bike and everywhere I went, the price was way more than what I wanted to pay. I wanted a bike that was well constructed, lite, and has high rated parts on it. I found this bike and I compared the price with a comparable bike at a bike shop and it was nearly $100 cheaper, plus free shipping. After we received the bike, we were very satisfied of the product except for the seat, but you can purchase a nice gel seat for around $15. Great deal!
