New Bibycles 2014
the newest bikes for 2014 and 2015 enyou
Another 27.5-inch model, the Troy proved its value last week when Devinci pro Steve Smith won the Fox Air DH aboard the bike. The Troy has a 140mm rear end and uses Dave Weagle’s Split Pivot suspension. The aggressive trail bike will be available with a 140mm or 150mm fork, a FD front derailleur mount and 142x12 Maxle rear axle (Smith’s bike, shown here, has a 160mm front fork and components from his sponsors, SRAM and Rockshox). Devinci will make limited numbers of the bikes available late this fall, and a full production run will follow in the spring.
The 140mm Sight now comes in three carbon versions, in addition to the two existing aluminum models. The carbon frame drops about a pound compared the metal option, but uses the same geometry and 27.5-inch wheel size. The frame has fully internal cable routing and will accommodate Stealth-style dropper posts. The Sight Carbon has aluminum chainstays to help it survive harsh rides, Norco says. The two higher-end versions are designed for single-ring drivetrains and will not accommodate a front derailleur. Additionally, the new frame has a BB92 bottom bracket. The top model in the line retails for about $7,000, and weighs 25.5 pounds.
Trek’s slopestyle athletes have been riding versions of this frame for years, but it has not yet been offered to the public. Now the company is launching a new program called Race Shop Limited, through which it will sell limited quantities of pro-level bikes and gear. The Ticket S, available in November, is one of the first products available through the program. It’s the same frame Brandon Semenuk used when he won this year’s Crankworx Joyride slopestyle contest. The Ticket S uses Trek’s ABP rear-suspension design and comes with the company’s Mino Link, which allows riders to slightly slacken the head angle and lower the bottom bracket. Trek will offer four signature versions of the $1,500 framesets. The first one available will be this stars-and-stripes-inspired package, which mirrors that ridden by Trek athlete Ryan Howard
Last year, Brandon Semenuk asked Trek to modify his carbon Session 99 downhill bike for the Red Bull Rampage big-mountain freeride contest. He wanted more agility from the bike, and also a more progressive shock rate to withstand the massive forces incurred when he touched down after sailing off the venue’s 30-foot drops. Trek responded by shortening the chainstays from 441mm to 420mm and changing the shock tune. The company also reduced travel from 210mm to 190mm. Those changes also make the Session great for riding in bike parks. Trek will sell a limited numbers of the $4,500 carbon frameset this year.
With a nod to the growing popularity of enduro racing, Rocky Mountain introduced two limited-edition versions of its 150mm-travel Altitude. Compared to the standard versions, the Rally editions have more parts optimized to withstand abuse and offer more control at the high speed you see while charging down descents. The Altitude 770 has wide Stan’s Flow 27.5 wheels, a 160mm Fox 34 fork, 780mm Race Face Turbine bar, and a Fox CTD piggyback shock. The carbon 770 shown here will retail for $5,400; an aluminum model costs $3,300.

Bicycle Exercise
Starting Position
Begin by lying on your back, placing your hands behind your ears. Do not put your hands clasped behind your head. Lift your legs in the air and bend your knees so that your legs form a 90 degree angle.Action
Move your legs in a bicycle motion. When your left knee is closer to your body, reach your right elbow to it. When your right knee is closer to your body, reach your left elbow to it. Try performing the exercise for 60 seconds in 2 sets.Special Instructions
None.Bicycle Crunches
With Bicycle Crunches, or Bicycle Kicks, you extend your legs into the air, like your pedaling a bicycle. You will perform this exercise as a variation on ab crunches. The difference is that you always have both feet off the ground during these bicycle crunches.This makes bicycle crunches a bit harder, than standard ab crunches. Also, it tends to work the lower abs more. Typically, keeping your legs off the ground works the lower abs. Keeping your legs flat, on the other hand, works the middle abs.

Also, it tends to work the lower abs more. Typically, keeping your legs off the ground works the lower abs. Keeping your legs flat, on the other hand, works the middle abs.
Interestingly, bicycle crunches also work the rectus abdominus muscle (upper abs). This is the highest set of ab muscles you have. When people refer to the “eight pack” as opposed to the “six pack” these are the two muscles they are talking about. So, if you want an “eight pack” make sure to include bicycle crunches in your workout.
If you are having trouble with bicycle crunches, try difrend crunches. When you get a strong core, you can “graduate” to bicycle crunches where you keep both feet off the ground
To do the Bicycle Crunches Exercise:
- Lie face up and place your hands behind your head, supporting your neck with your fingers.
- Have your abs tucked in and the small of your back pushed hard against the floor
- Lift your knees in toward your chest while lifting your shoulder blades off the floor.
- Rotate to the right, bringing the left elbow towards the right knee as you extend the other leg into the air.
- Switch sides, bringing the right elbow towards the left knee.
- Alternate each side in a pedaling motion for 3 sets of 12 reps.

Best Items For Your Mountain Bike
New Tires – Can breathe new life into any
tired bike or allow you to tackle terrain in a completely different way.
Old, worn out tread doesn’t offer much traction and new tread designs
and compounds come out each year. Maybe you’ve always rode the same
tires year in and year out and should try something new. Ask your
buddies or your local shop what they like to ride.
Tubeless Kit – Riding tubeless allows you to run lower pressures and avoid punctures. For mountain bikers tubeless is a no-brainer. The setup is often lighter than tubes so you have less rotating mass to accelerate or decelerate. If you don’t have tubeless wheels it’s easy to buy a conversion kit or research Ghetto Tubeless (remember to buy tubeless ready tires).
Wider Handlebar – Have you not jumped on the wide bar trend yet? If you haven’t, you should give it a go. It puts you in a much better riding position with a lot more leverage for climbing. The aggressive guys have been running wide bars for a while now but I think everyone should try them out on their ride.
New Grips – Speaking of contact points, a new set of grips is always a great purchase. Grips get worn pretty heavily if you ride a lot and new ones always feel so nice and plush. If you haven’t got a set of lock-on’s you might look into those as well. They are much more secure.
Better Pedals – The contact points of a bike are very important. One of the most important parts of a bike in my opinion is the pedals. Once you’ve ridden a good set of wide platforms with aggressive traction pins or a dialed set of clipless pedals, you’ll notice you have a lot more confidence in rough sections of trail. I suggest platforms from Twenty6 (made in the USA), Point1 Racing, (made in the USA), or Straitline (made in Canada). For clipless I stick with Shimano XT / XTR or Time.
Riding Shoes – Riding shoes go hand in hand with pedals. Good mountain bike shoes with the right rubber compound can make a huge difference. They stick to the pedals better and have a stiffer sole for better power transfer. For those that ride platforms 5.10 is the best you can get. Their rubber compounds sticks to pedals like glue. If clipless is more your game Specialized, Giro, Shimano, and Sidi all make some of the best MTB clipless shoes
Riding Specific Eyewear – If you ride in a lot of different conditions a pair of sunglasses with interchangeable lens come in very handy. I’ve had riding glasses with multiple tint lens for a while now and never ride without them. It’s nice to be able to switch to orange, yellow, or clear in low light conditions.
Nike is developing a pair of glasses for bike riding that could very well save your life. The glasses will extend your peripheral vision so that you are able to see objects behind you. The Nike Hindsight glasses have a special lens on the sides that allows for a field of view greater than the human limit of 180º. It will give you an extra 25º of viewing on both sides, making you see things like some bugs no doubt see the world.The lenses distort the images on the side but the human eye can only detect motion in that area anyway, so the image will remain clear to you. You’ll be able to see cars or pedestrians coming up from behind you. It’s still a concept at the moment, but I’m sure this is one we will actually see in about 5 years or so.
if you have all this then you're redy for riding go for it people .:))

Road Bikes or Mountain Bikes or Hybrid bikes
Road Bikes are designed for riding on paved streets and going fast. Featuring skinny tires, a lightweight frame and a riding position that puts you bent over the handlebars, you might choose this type of bike if traveling longer distances at higher speeds is important to you.
The frames of most road bikes are not particularly beefy in construction and generally won’t stand up well for extended periods under heavy loads or on really rough surfaces. They are about as well-suited for a path in the woods as you would be when wearing high heels.
Mountine Bikes have exploded in popularity over the past twenty years. These bikes have wide tires, usually with knobby treads and a stout frame, and are designed to handle the rugged trails without disintegrating.
Mountain bikes do not go as fast as road bikes, which is a trade-off for their durability along with a more comfortable riding position. You sit higher on these bikes, more upright with the straight handlebars, which is often a happier choice for people with back problems than being hunched over as you are on a road bike.
Warning: sometimes mountain bikes are the default choice of salespeople at the bike shop because they are easy to sell and usually less expensive than road bikes. Too many times though, new mountain bikes with lots of impressive features for climbing a steep mountain trail end up like those four-wheel drive SUVs that never actually go off the pavement. If you are going to buy a mountain bike, make sure you are doing so intentionally because you know that you will in fact be riding off-road. Otherwise, you will be paying for unnecessary features, and probably missing out on a bike that would be a better choice for you.
Hybrid Bikes are compromise between road and mountain bikes and offer the best features of both if most of your riding will be shorter trips on pavement. With skinnier, smooth tires, they typically can go faster than mountain bikes, yet feature the upright seat and handlebar position that many people favor.
Hybrids are a good choice for most city riding, and offer speed, durability and comfort

Why Bike?
1.Riding a bike offers many health benefits. Here are just a few:
Plus, being out on your bike is just flat-out fun. The more time you spend on two wheels, the harder it is to take yourself too seriously.
You don’t bring with you the noise that a car generates and are actually able to interaction with people as you move. From my bike I can wave to a neighbor, say hi to a kid, smell someone’s dinner cooking and be a warm and friendly human presence on the streets.
Also, not insignificant: operating a bicycling does not harm the environment. There is no polluting exhaust released, no oil or gas consumed. And the energy and materials used to manufacture one automobile could be used to created a hundred bikes.
Though cars will certainly make better time on long trips, you’ll find for many short trips or through heavy traffic, you can travel just as fast or faster on your bike.
Have you ever been to a massive festival or concert in a park somewhere, the type of event that draws so many people that just getting there is a problem? Going in on a bike is a perfect solution. Zip in, zip out. You don’t have to get there hours early to get a parking spot or else face parking miles away from the event. And you won’t have to wait hours in traffic to get out once it’s over.
When you start multiplying cost per mile to operate a car by the distance you ride, you can easily calculate how much money you save by riding a bike.
For example: my daily roundtrip commute is 16 miles. If I do that just twice a week, I will save over $400 in operating costs alone in the course of a year. (16 miles x 2 trips per week x 52 weeks x .25 cents per mile.)
And if you would otherwise have to pay for parking, tolls, and the like, don’t forget to factor that in too. It can add up quickly.
So for all these reasons, get out there on your bike today. Even if you don’t save the world in the process, you’ll still have fun trying!
- increased cardiovascular fitness
- increased strengt
- increased balance and flexibility
- increased endurance and stamina
- increased calories burned
2. For Your State of Mind
Riding a bike is a proven stress releaser. Regardless of if you are riding purely for pleasure or for a specific purpose, you will arrive at your destination feeling relaxed, energized and happier about the world and yourself.Plus, being out on your bike is just flat-out fun. The more time you spend on two wheels, the harder it is to take yourself too seriously.
3. For Your Community
Being out on your bike is good for the people around you as well. You are able to go the places you want to go and yet put one less car on the road.You don’t bring with you the noise that a car generates and are actually able to interaction with people as you move. From my bike I can wave to a neighbor, say hi to a kid, smell someone’s dinner cooking and be a warm and friendly human presence on the streets.
Also, not insignificant: operating a bicycling does not harm the environment. There is no polluting exhaust released, no oil or gas consumed. And the energy and materials used to manufacture one automobile could be used to created a hundred bikes.
4. For Convenience
There is an undeniable convenience factor you’ll discover when riding a bike. Front row parking spaces are guaranteed no matter where you go. Traffic jams are also irrelevant.Though cars will certainly make better time on long trips, you’ll find for many short trips or through heavy traffic, you can travel just as fast or faster on your bike.
Have you ever been to a massive festival or concert in a park somewhere, the type of event that draws so many people that just getting there is a problem? Going in on a bike is a perfect solution. Zip in, zip out. You don’t have to get there hours early to get a parking spot or else face parking miles away from the event. And you won’t have to wait hours in traffic to get out once it’s over.
5. For Your Pocketbook
It costs between 20 and 30 cents per mile to operate a car, depending on the vehicle. This is based on expenses like gas, oil, maintenance, etc., that go up when you drive more. This figure doesn’t include the hidden costs of vehicle ownership like depreciation, taxes, and insurance. These factors make the actual per mile cost to operate a car much higher.When you start multiplying cost per mile to operate a car by the distance you ride, you can easily calculate how much money you save by riding a bike.
For example: my daily roundtrip commute is 16 miles. If I do that just twice a week, I will save over $400 in operating costs alone in the course of a year. (16 miles x 2 trips per week x 52 weeks x .25 cents per mile.)
And if you would otherwise have to pay for parking, tolls, and the like, don’t forget to factor that in too. It can add up quickly.
Ride For You
When you ride your bike, you are doing a lot of good things, many of which are for the benefit of others. But ultimately, the one who benefits the most is you, through better health, peace of mind, increased confidence and self-reliance, heck, even through a fatter bank account.So for all these reasons, get out there on your bike today. Even if you don’t save the world in the process, you’ll still have fun trying!

Beginner's guide to mountain biking
What bike?
Essential equipment-------------
1 Bike
The bicycle is a complicated machine, but when it comes to choosing one all you need are some basic measurements – your height and inside leg – and a trip to your local bike shop (LBS).
Yes, you can find some cheap deals online, but it's all too easy for a beginner to make a bad choice and end up with an unsuitable machine. Your LBS will be able to help you find a bike that fits you properly and is suitable for the sort of riding you'll be doing.
Most shops are run by biking enthusiasts who are only too happy to answer all of your questions. I’m sure your local shop will be able to help you
The first question you should ask is' what is the best starter bike for me?'. There are three main types of mountain bike:
1 Rigid: A rigid bike has no suspension. This saves weight, cuts down on maintenance and means there is less to think about when you are learning to ride off-road. But on rocky or rooty tracks your comfort and control will suffer. A rigid bike is always preferable to a bike with poor suspension, so they're a good buy if you can only afford a couple of hundred quid.
2 Hardtail: As the name suggests, this is a bike with a hard – ie. un-suspended – back end and a suspension fork at the front. This type of bike helps you tackle more technical terrain. They're heavier than similarly priced rigid bikes, but cheaper, lighter and have better handling than entry-level full-suspension bikes. For a new bike with a decent budget fork you should be looking at paying upwards of £400. This is the type of bike we’ve chosen for the start of this series.
3 Full-suspension: Full-suspension bikes have suspension at both the front and rear, which improves comfort and helps you ride more technical terrain. The downside is increased cost – it's difficult to find a decent new bike for under £800, except in the sales – and weight, plus more moving parts to break or wear out.
Me muself i prefere Hardtail.I have Specialized hardtail from 2011 and so far it's great :)

Bicycle
A bicycle, often called a bike (and sometimes referred to as a "pushbike",pedal bike","pedal cycle", or "cycle"), is a human-powered, pedal-driven, single-track vehicle, having two wheels attached to a frame, one behind the other. A bicycle rider is called a cyclist, or bicyclist.
Bicycles were introduced in the 19th century in Europe and now number more than a billion worldwide, twice as many as automobiles. They are the principal means of transportation in many regions. They also provide a popular form of recreation, and have been adapted for use as children's toys, general fitness, military and police applications, courier services, and bicycle racing.
The basic shape and configuration of a typical upright, or safety bicycle, has changed little since the first chain-driven model was developed around 1885. But many details have been improved, especially since the advent of modern materials and computer-aided design. These have allowed for a proliferation of specialized designs for many types of cycling.

Mountain Bikes
Mountain bikes are typically ridden on single track trails, fire roads,
logging roads, and other unpaved environments. These types of terrain
commonly include rocks, washouts, ruts, loose sand, loose gravel, roots,
and steep grades (both inclines and declines). Mountain bikes are built
to handle this terrain and the obstacles that are found in it like
logs, vertical drop offs, and smaller boulders.
