I'm not going to comment on the bike (primarily because of that I am going to comment on)... but really... what *totally useless* specs to post about a bike:

-Gear Speeds: 21
-Bicycle Frame Height: 15"
-Bicycle Frame Material: Aluminum
-Seat Material: Polypropylene, Nylon
-Bicycle Chain Material: Steel
-Pedal Material: Resin
-Rim Material: Aluminum
-Front Wheel Height: 28"
-Rear Wheel Height: 28 inches
-Tire Type: Smooth
-Tire Width: 1.95"
-Maximum Weight Capacity: 250 pounds
-Dimensions: 68 inches L x 41 inches H
-Weight: 38 pounds

There's nothing there that would let anyone knowledgeable about bikes make any informed decision on the quality (or lack thereof) of this bike.

Cheers
