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

Customer Reviews

Careful with buying replacement tubes
I received this item yesterday, and assembling it was no problem for me.
I have no experience with bikes and I figured it out pretty easily.
You just need to make sure you have some allen wrenches on hand.
I did run into one pretty big problem. I broke the valve on the inner tube,
which was totally my fault, not the bikes. I went to a local bike shop to get a replacement
and it’s a really weird size. Not standard AT ALL. The guy had actually never seen
a bike that needed that size. I went home and called around to other places
to try to find it and luckily a bike shop had found a place to order them
because people had been coming in with this same bike! He knew exactly which bike
I had before I mentioned it, just because of the weird replacement tube.
So, a flat tire when riding is inevitable and you’ll need replacement tubes,
but the ones you need have an extra long valve stem.
The size you will need is 700×28c tube, 48mm shrader valve stem.
I would recommend you call and see if your local bike shops have this size,
because if not, then you will find it hard to fix a flat.
Hope this helps!!

Defective Purchase
I was very excited to get my bike as I decided to start riding into work as my daily
workout verses going to a gym. When I called to order the bike
I was told it would be assembled, when I received it, it was not. You need 3 different size
wrenches to assemble and nothing is quick release on the bike.

The short story is that I had 3 flat tires in 3 weeks which meant I did more walking
and spending time in a bike shop then I did riding my bike. It was determined
that the wheels were defective and I just could not spend any more time
or money hoping I would be ok. One other issue was with the gears,
they made noise no matter how much the bike shop tried to fix it.

I have returned this bike to Amazon unfortunately. Amazon was great
about honoring my warranty and sending a return label. It may have
just been bad luck on this particular bike.

Great Value
I really like this bike…I had never ridden a road bike (or any bike with brakes on the handle bars)
until this one. The brakes are a little hard to reach, but overall the bike has been great!
I am very happy with the purchase.
