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

5.0 out of 5 stars Polaris RMK and Victory Vegas Low, November 29, 2010

This review is from: Polaris RMK Adult Dual Suspension Bike (Sports)

11-29-10. This will not be a standard review but will have some helpful hints---hope it will help you.
My Goal was to find (using reviews and ratings) the best dual suspension/disk brake mountain bike
for under 300 dollars
Based on reviews and ratings from different web sites it came down to the following three.
1. GMC Topkick, made by Kent Bicycle.
2. Polaris RMK made by Ming Cycle in Taiwan (seen above)
3. Victory Vegas Low---Ming Cycle

Although the GMC Topkick is a 4-star bike, I ruled it out because it is more bulky looking and it
is a few pounds heavier than the other 2 bikes and there were many reviews claiming a front dérailleur
shifting (inherent) problem and complaints the handlebars could not be raised.

The Polaris RMK comes in with great reviews and a 4 1/2 star rating. But in just one day Amazon raised
its price from 199 dollars to 267 dollars(nov 20,2010). -----After some more investigation it turned out
that the Polaris RMK is exactly the same bike as the Victory Vegas Low only with different colors and name.
The Victory is selling for a lot less than the Polaris and is (as of this date)189 dollars at Meijer,(where
I bought mine, see below).

The Polaris and the Victory are made by Ming Cycle out of Taiwan and distributed by an
American company---Cycle Force Group. Ming Cycle makes different brand name mountain bikes,
like Polaris, Kawasaki, Victory, Mantis, all of these can be found on Amazon and retailers
like Wall Mart, Target and Sears.------As it turns out the Polaris and the Victory are Ming's top
of the line dual suspension mountain bike with upgraded wheels and front disk brake and 19"frame
and generally reviewed and rated better than some of the mountain bikes that sell for more. So based
on reviews and ratings I think for a dual suspension mountain bike with front disk brakes
the Polaris or Victory is the way to go ---except that the Polaris price has been increased too much,
So go with the Victory Vegas Low, its the same bike!!!! and can be found on amazon but It can be bought
as of todays date 11-30-10 at Wall mart or Meijer's for under 200 dollars and with free shipping.

---A review for Victory is a review for Polaris and vise/versa. See my complete review for the Victory
on Amazon and Walmart.----Best dual suspension mountain bike for the money. 5stars

12-12-2010---Now Amazon lowered their price again even lower than the Victory Vegas and you can find it on Miejers for 187 dollars. Apparently Amazon raises the price when Walmart and Miejiers runs out of stock, then when they get restocked and have the lower price Amazon lowers their price------Anyways they are both the same bike so you have your choice of colors and one of them will always have the lower price.

1.0 out of 5 stars DO NOT BUY, September 1, 2011

This review is from: Polaris RMK Adult Dual Suspension Bike (Sports)

I read all of the reviews, thought that it was going to be a great bike. It came with a flat, the rear brakes did not work, the front brakes eventually gave out (2 weeks) the gears hardly switched, and it just felt like riding a bike that had 200 miles on it. I ended up returning the bike, it was really bad. Every time I went and road this bike, I had to tweak it and fix it when I came back. SAVE YOUR TIME AND MONEY, DO NOT BUY THIS BIKE. I suggested my friend buy it as well, and he had all of the same problems as I did. I don't know who reviewed this, but it was just pathetic. DO NOT BUY!!!
On a positive note, it only took me 5 days to get my money back after returning it. DO NOT BUY! I'm not kidding this thing is a real piece of junk.

This review is from: Polaris RMK Adult Dual Suspension Bike (Sports)

This bike arrived damaged. The box was torn open, and the crank was bent and destroyed. Even if it had arrived intact, the bike is considerably smaller and of a lesser quality than advertised. I still have not received my reimbursement, although I have sent the product back and submitted my return form at amazon.com. A COMPLETE WASTE OF TIME AND MONEY!
