I drive a isuzu trooper which gets about 9 mpg and i wanted to start biking to school and work instead of burning my money away on gas. So i went to a couple local bike shops in town and found two i liked. my favorite was a hybrid trek bike, but it was $480!! Im a broke college kid with stingy parents, so i was on my own. With this bike, i was thinking with the price, it must be junk.. I was very much mistaken, when i got the bike, i was very pleased. The bike looks good in the pictures, but its even more pretty in person. Im used to riding mountain bikes, so the set up with this road bike is very different. i didnt know that the seat was supposed to be level or HIGHER than the handle bars. for me it was weird at first, but i got used to it pretty quickly. so dont think the bike is too big for you, im 5' 10" and it fits me perfect. After a couple weeks of riding the bike, i took of the GMC stickers so i could put on my own.. bad idea. it looks like they dont completely finish the paint job under the bigger stickers, so i dont recommend it unless you have nicer looking big stickers to cover it. out of the box, it is very easy to assemble. Just attach the seat post, front wheel, and handle bar stem. The only negatives I would have to say is; the seat is kind of hard for long trips, (but what would you expect), a couple of the parts that come reassembled came loose within a couple times of riding (so dont assume whatevers assembled in the box is nice and tight) and- it might have been just mine, but the first time i rode my bike to school (7 miles downhill) when i got to school, walking into my first class i heard a "pssssssshhh" and the tube in my tire released allll my air. luckily theres a bike shop across the street that checked it out and said it was a defective tube, not really the bikes fault but just be aware of that small stuff. the PROs: very smooth shifting up and down hill, I can hit 40 MPH going downhill and still have enough tension on the pedals to go faster, the lowest gears allow very easy climbing for steep uphills, and the best thing- its really sexy! its a really good looking bike, GREAT for the money, and it seems like it will last me a looong time. so if your on a budget and cant afford a 500 dollar road bike, or you just want to give it a try, i really recommend this bike. its very fun, great value for the price, and very efficient.
