Amazon.com Bicycle Buying Guide Finding the Right Bike To really enjoy cycling, it's important to find a bicycle that works for you. Here are some things to keep in mind when you're in the market for a new bike:
The Right Ride In general, bikes are broken down into three major categories:
Road and Racing Bikes--As a general rule, road and racing are built for speed and longer distances on paved surfaces. Thinner tires, lightweight 29-inch (700c) wheels and drop bars that allow for a more aerodynamic position are the norm. Most road bikes, regardless of price, offer many gears for tackling both hilly and flat terrain.
Mountain Bikes--With their larger tires, hill-friendly gearing and upright position, mountain bikes are very popular for all types of riding, both on pavement and off. Mountain bikes that are designed specifically for rugged trail use typically feature a suspension fork. Some may have rear suspension, as well. A quick change of the tires on any mountain bike--even one that you use regularly on trails--adds to its versatility and makes it a worthy street machine.
Comfort/Cruiser Bikes--For tooling around on bike paths, light trails, or for cruising a quiet beach-side lane, comfort/cruiser bikes are the ticket. With a super-relaxed riding position, padded seats, and limited or no gearing, these bikes are made for enjoying the scenery and having fun with the family.
The Right Price A bike's price boils down to three essentials: frame materials, bike weight, and component quality and durability.
Entry-level--You'll find a wide range of comfort and cruiser bikes in this category, as well as some lower-end mountain bikes and road bikes. Most will have steel frames and components that are designed to last for several years with frequent use.
Mid-range--Bikes in this range may feature a lighter aluminum frame with mid-range components that keep performing after miles of use. If you're looking for a quality bike that is relatively lightweight and will stand up to abuse, this is the "sweet spot." Most serious commuter and touring bikes fall into this category, as do mid-range mountain bikes with a decent front suspension.
High-end--Racers and serious enthusiasts who expect lightweight, high-performance components will want to stick to this category. For road bikes, exotic frame materials (carbon fiber, titanium) and ultra-lightweight components can add thousands to the price tag. Mountain bikes in this class often feature advanced front and rear suspension technology, as well as components designed to handle lots of rugged trail action.
The Right Size Fit is crucial for comfort, control, and proper power and endurance on a bike. Here are some basic bike fit tips:
Stand-over Height--To find out if a bike's overall height fits your body, measure your inseam. Next, determine how much clearance you'll need between your crotch and the top tube of the bike. For a mountain bike, you'll want three to five inches of clearance. A road bike should offer between one and two inches of clearance, while a commuter bike should have two to four inches. Compare the stand-over height for a given bike to your measurements (inseam + clearance) to determine the right bike height.
Top Tube Length--You can measure your torso to get a good estimate of proper top tube length. First, make a fist and extend your arm. Measure from the center of your fist to the end of your collarbone (the part that intersects your shoulder). Next, measure your torso by placing a book against your crotch with the spine facing up. Measure from the spine to the bottom of your throat (the spot between your collarbones). Finally, add the two measurements (arm length + torso length), divide the number in half and subtract six inches. This is your approximate top tube length. Compare this number to a bike's posted top tube length. You can allow for about two inches longer or shorter, as most bikes can be adjusted via stem length/height and saddle fore/aft position to make fine adjustments to the fit.
Bikes for Women--Proportionally, women tend to have a shorter torso and longer legs than men. Bike makers design women's bikes that offer a shorter top tube and many comfort/cruiser bikes built for women may also provide more stand-over clearance.
The Right Accessories When you make a bike purchase, don't forget these crucial add-ons:
Helmet (this is a must!)
Seat pack
Lock
Hydration pack, or water bottles and bottle cages
Spare tubes
Portable bike pump
Gloves

Putting it together:
The bike came with the typical assembly needed for a bike shipped in a cardboard box. Attach the steering column, front tire, seat, pedals, reflectors. Then adjust brakes and fine tune gears. No big deal. Several different size allen wrenches, open end wrenches, pliers, and a screwdriver were needed. It was not hard, but if you've never put a bike together before it might seem like a lot of work, and you still might wind up at a bike shop for proper gear and brake adjustments.
Initial thoughts:
It is a nice looking bike and since road bikes are pretty much only sold in bike shops, most people will assume it cost a LOT more than it really did. A friend asked if I spent "over $1,000" on it.
I have no problems with build quality. The welds look good, the bike seems solid, the seat tube fit fine. I was surprised how well the frame fits my 6'0" size.

Let me start with some history. Thirty years ago I worked a summer job as a Schwinn bicycle mechanic. I loved that job. In the process I assembled a ton of bicycles. I also purchased a Schwinn Continental 10 speed. Thirty years ago that was a great bike. Even by today's standards it would be a cool bike. That bike was stolen in 1982ish.
Move forward to 2006. I started getting the itch to ride a bicycle again. I tooled out to WalMart and bought one of those RoadMaster MtFurys for 53 bucks and rode it everyday. I decided I wanted a road bike since I was riding farther and longer, week by week. So, I ordered the 63cm GMC Denali from Amazon.
The bike arrived through the US mail in a box that looked like they dragged it behind the mail truck for a few miles. I was worried that something was broken. Nevertheless, I opened er up and the bike was fine. They packed it in a manner that allows it to take a bit of a beating in shipping. Since I was an old... Read more

The Denali is typical of mass produced, imported, department store bicycles. It will need some tinkering and adjustments, the extent of which will depend upon your experience, tools and desires. Most riders opting for this road bike will want to do things like true the wheels and adjust the brakes and derailleurs. They are close out of the box but need tweaking. Aesthetically, it is pretty with its anodized blue look, accented with black and silver stickers. The wheel stickers make the bike look expensive, but the metal name plates on the frame are a bit tacky and look like they're about to fall off (although you probably couldn't pry them off if you wanted to). Newer models don't have the name plates.
Problem areas on my Denali were the brake lever hoods (which began splitting after a few day's use), less than desired stopping power, and a bottom bracket lock ring that needed tightening. Installing upgraded levers with better hoods eliminated the splitting, and better... Read more
