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

Good Strong solid bike
These are great bikes for entry level or people who don't plan professional biking career. I got it well packaged, easy to assemble, nothing really to do except mounting the front wheel and putting the breaks in place afterwards, then mounting the pedals. I ride it along with my son, on a back mounted children seat I got from Ross. shifts are easy and smooth, it needs calibration, as any other shifts. they are not the lightest bikes, but it's strong, I'm loading over 300 pounds on them with my son. The seat is reasonable, not very soft, and it's good that it's not that small tiny seat because for big people that one is a pain in the... but you know, it takes few rides for the ... to get used to those seats. Tires are good, I may replace them with less mounty ones, since i drive it on roads and paved tracks, not really down hill wild rides.
Nice bike for a kid but disappointing
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 9. 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 9. 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!
Only thing good about this bike is the price...
Like other reviewers have pointed out the brakes on this thing are flimsy and its only a matter of time before the fail to work properly. Shipping was free and it looked that way when I received the bike. Shipping was so bad my rear rim was so bent it would not spin. Also the front forks/shock system was so badly put together I had to take it to the local bike shop and have them redo it. When riding the gears would automatically change. I'm sorry to say I do not recoomend this bike. Take your money and invest it into a better bike. I wish I had :(
P.S One good thing about this bike is it has a sturdy aluminum frame. Thats about it.
Could be better
Amazon did their job quite well, it is GMC who did not perform so great. The bike arrived well ahead of schedule, however, the bike is not very well built. The frame is solid, the brakes and gears are a bit cheap, and they gave me a different seat than what was pictured(it is a big old granny seat). If you were to put new brakes and maybe a new gear set on this bike it would be about a 400 dollar bike. So it is overall a project bike for me, otherwise a great starter bike for someone who does not ride often.
Good looking bike, that's all.
Worst packaging ever. There isn't any type of protection between components. The frame and tires are tied up each other with plastic ties, that's all. I would assume that they would at least put some foam protection between the tires and frame, and around the frame.
There was not one single page of instruction about how to assemble it. You don't have to be a genius nor is it too hard to figure out but I wasn't sure about few small things and it would be great if I had a choice to look them up.
The worst part is that the bike requires assembly and there was not one single disposable tool to do the job. I mean come on, even the coffee maker comes with some type of tool to assemble it, they just assume you should have the tools. Forget having the tools, there is nothing to tell you what type and size of tool you need, so you can't go and get anything from your local home depot, you will have to try and find out what fits.
The first thing I noticed was the one of the shifters was broken. It's made of really cheap plastic so no wonder it didn't make it the infamous UPS handling. But let's not blame UPS, if it was packaged properly, nothing would have happened.
Here is the funny part; the handle bars were assembled upside down. I attached it to the frame but it looked funny then I turned it the other way around to find out, it was assembled wrong. I have no comment, you be the judge of that.
Overall, the bike looks good, with fancy painting and labels, although few labels were not attached completely. Unfortunately I cannot say anything about the performance since couldn't make it to road. I couldn't try but the seat doesn't seem comfortable.
I should say it seems "OK" bike for people who intend to use it for joy rides once a week. However, I have to inform you that it is made of cheap materials, but then, you get what you pay for.
I read bad reviews about Kent who seems to be the manufacturer and/or distributor of this bike. I agree with them and I chose not to buy anything from them again. This was my first purchase for a bike and it went surprisingly disappointing. It's very disappointing when you wait for something impatiently and then find out you have to return it, search again for new one, wait another week or so, etc...
Maybe buying a bike online wasn't such a great idea but I thank you Amazon for making returns painless for us.
