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 bottle and bottle cage
• Spare tubes
• Portable bike pump
• Gloves

I bought this bike thinking it would at least be decent. Within 500 miles of ride time, both brake sets had to be replaced, the hinges were weak and the screws might as well have been made of pewter, so after one re-adjustment of the brakes, they would no longer release, a week later the threads holding the screws stripped off and no longer held the cables in place. The cassette was almost completely destroyed after 500 miles, even with a new chain I couldn't pedal in 4th-7th gear or it would slip if any pressure was applied. The rear wheel was out of true when I received the bike and came out of true again, within 80 miles of street riding. After about 400 miles, the left cheap plastic pedal broke through leaving me with a bolt to pedal with. To top it all off, after the 500 miles of riding I got out of this bike the hub in the crank went out. This is a disgrace to be called a Mountain Bike. Do not buy this bike, save your money and get a run of the mill Kona or Trek. I wouldn't even buy another bike from Kent at this point, The fact that they would even release this product is beyond me.

The only good thing about this bike, as you will see from other reviews, is that it has a sturdy frame.

It's quite an interesting role-reversal assembling this bike for my dad.

I've only ever owned and ridden cheap Huffy/Murray type bikes which a real biker will tell you is hardly a bike at all. This bike must be closer to the real deal because it blew away all my preconceived paradigms for bikes. The frame is very solid. It's made with really beefy aluminum tubing, solid welds, and additional bracing plates. It was stronger than the bikes of my youth and lighter too. 21 speeds are definitely better than 4. The front wheel nearly came off the ground when I took off the first time.

Let's make no mistakes about this. It was not intended for a hardcore rider. My dad just needs it to get from A to B on smooth pavement. The brakes DID seem a bit on the flimsy side when I installed them, which agrees with another reviewer. But it performed fine so I didn't give it much more thought. The gear shifts were a little balky. It hesitates to find the gear sometimes and is a bit rough when it finally engages. The thumb shifters were tight and required a decent bit of effort.

I'm still happy with the bike. For $170, I didn't expect anything better. I was more than satisfied. Though if I had to make a recommendation, I'd say buy a used bike. For the same price, you could probably find a good used Trek/Cannondale/Schwinn on Craigslist.

2.0 out of 5 stars Nice bike for a kid but disappointing, July 2, 2008

The bike frame was welded together wrong! The front wheel could not be put on the bike because the arms were not aligned. How can they make a bike so obviously defective and try to sell it? IF the bike had been correctly manufactured, it would have been the perfect bike for my 13 year old son. The quality of the bike itself was OK, a few things probably should have been a bit more quality, like the pedals, they were plastic, not good for $169. I'd say if you are a serious biker, this is not the bike for you. If you ride a bike for lesiure or family time, it would be fine.
Buying through Amazon was great, I was able to return the bike, free shipping, and was credited back the $169. I love buying from Amazon, they make it so easy for you, if your purchase doesn't work out. So don't tear the box up until you know the bike is a keeper!
