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

 for the price great July 5, 2008
J. Larsen (NJ, USA)
had it out for the first long trip today and it was fine. Some of the gears make a bit of noice, but I was happy with a few that worked fine. For 110$ you cannot expect more, and the design is great when all the stickers are taken off. Mine will be parked at a train station during the day,so didnt want to spent a fortune , and this is perfect for that purpose and a long ride once in a while in the weekends.

While functional and relatively agile, I have never felt terribly safe riding this bike. The brakes, even after attentive alignment and tightening, are unresponsive. In addition, the brake levers are only accessible when you are in a full crouch, which is fine for long rides on trails but crummy when you're trying to navigate urban areas. The front derailleur arrived completely misaligned, and took about two hours of adjusting to get functional. Other folks' comments about the wheels needing truing are spot on. I'm not a bike snob, but I do feel that by the time you fix all the problems with this bike you might as well have bought a better bike from a good shop, and you'd have a much better ride.
The single most bothersome thing about this bike to me, and this may be due to the fact that my previous road bikes were vintage models and frame design has changed, but the pedals in their forward position intersect the back of the front wheel, so if you turn hard while peddling you can get all tangled up, which is Bad, and extremely inconvenient in urban settings where you might need to get started and head around a tight corner at speed.

I spent over a year looking at various cycling products before I purchased this bike. I decided that if most of the components were crap I would replace them with quality parts. The crank, bottom bracket, pedals, are all garbage. The handle bar neck is too short for me as is the seat post. Other than that I love the bike and was able to keep more than I thought I would. The front gears are mountain gears and too small for me so I reccommend a complete crankset replacement. The derailers are not great but I love the Shimano revoshifter gear shifters, so I'm keeping them for now.

Complete Lemon. Don't by this bike. I thought I could get a cheap bike to start biking and upgrade components later. The first bike I received had a disformed front fork making it impossible to assemble. Amazon was very quick about getting me a replacement and getting the original picked up. Round #2 began with a $50 tune-up because the front inner tube had a leak, both breaks were practically unusable, the wheels were horribly out of true, and the rear shifter was about 1/2 gear off in position (all before a single ride).
After all of this, I still felt OK about the bike because I'm still less than half the cost of decent road bike. I took some leisurely rides and attended critical mass here in Chicago racking up about 15 miles on the bike. My only real complaint was that the brake calipers flex when used and look like they will break any time (more $$$). Today at 16.27 miles on my odometer, I cranked on the pedals to get back up to speed and I snapped the #6 rear sprocket (2nd smallest)completely in half. I nearly threw myself off my bike before I knew what was going on. I'm not even a big guy at 5'9" and 145lbs nor was pushing my hardest on the bike.
The bike is going back ASAP for a refund and I'm angry that I wasted more money on this POS.
Please do not buy this bike! August 26, 2007

I have seen many of these bikes around town, and all have been in very poor working order. This bike is designed to have the looks of a nice racing bike, but has none of the technology that goes into a decent bike to make it safe and longlasting. The brake calipers are flimsy, and should not be installed on a bike that is designed for the road. Also, the wheels are cheap and easily go out of true. If you do not have the skill to true them, you will have to shell out a good percentage of the original price to get them working correctly. The handlebar is cut in half to install the shifters and then welded back together. There is a lot of force on the handlebar of a bike, from holding your weight, forces when standing, and pulling on the bar. To cut a handlebar severely damages the integrity of the part, even if it is welded back together. Now while at first I had respect GMC for making a road bike that is low cost to let people try road biking, once I saw the bike I was shocked. The bike is not safe to be ridden. I also decided to go to a wal-mart and see one of these bikes for myself. The bike was in very poor working order. The breaks were making contact with the tires, the headset was loose, the seatpost wasn't tightened down, the derailleur hanger was bent in. The bottom line here is do not buy this bike, it is not safe. If you are interested in getting into road biking and think this bike is a good decision, realize that the money you will put into it to get it to work will not be worth it in the long run. You can purchase road bikes on craigslist and ebay for 200 if you look good enough for long enough. If you're only looking to put 100 into starting road biking, then now is not the time for you to start. If you would like further info on looking for bikes or why this bike is dangerous, please contact me: hewittd@unc.edu.
