Types Of Bikes
Cycling is a great way to get around on a very environmentally friendly pair of wheels and it keeps you in terrific shape. Cycling 10 minutes a day will give you a great cardiovascular workout and will get you out of the house and in the fresh air.
Studies suggest that 2,000 kcal a week of exercise is good, whereas 2,800 kcal helps control weight better. The human body, in short, is made to exercise; yet our increased motorized existence means that we now walk an average of 8 miles less than our forefathers did 50 years ago. Our sedentary lifestyles, thus, have led to an increase in cardiovascular diseases, strokes, diabetes and weight problems.
The best thing about a bicycle is that you can take it places a car can never go. Imagine getting away from the traffic jam because you can weave through the lined up cars. But if you are planning on biking through heavy traffic invest in a mask that will keep the pollution out.
Bicycles do not degrade the environment since they burn no fossil fuels. Studies have shown that a bike that replaces an automobile for all travel is equal to planting 170 trees. Cycles create no noise, no stink, no congestion and most importantly they do not require massive highways and extensive parking areas. You don't even need to pay for them like you have to pay for a car.
On the down side, cycling does involve some risk of injury. Head injury is the number one cause of death in cycle riders. So, in order to be safer it would be good to wear a helmet. Besides this, it is a good thing to follow traffic rules, stop for traffic signals and stop-signs and use lights at night.
Types of bikes
Trail bikes or Light-duty Mountain Bikes:
Most have 26" wheels, 21 - 24 gears (20" and 24" wheels for kids) Similar looks and features as mountain bikes, but usually not as light, rugged, nor expensive as real mountain bikes. Ideal for "careless" riders, college students, commuters, recreational, family riding.
Most have 26" wheels, 7 - 24 gears. Similar to mountain/trail bikes, but with less distance between seats and handlebars, a higher "front end" for more upright seating. Usually have shock-absorbing seat posts for fanny and seat comfort, some have flexible, shock absorbing handlebar stems or telescoping, shock absorbing front forks, wider, softer saddles, and wide pedals.Mountain bikes:
Most have 26" wheels, 21 - 27 gears. (Are VERY rugged!) Have rugged, stronger components and frames, intended for rougher, off-road riding in rugged terrain, over rocks and logs, but are often used on-road. Have fat, knobby tires for more traction and "cushion," flatter-profile handlebars for a more leaned-over seating position, very low gears for easier hill climbing.
Hybrid or Cross bikes:
Most have 700C diameter wheels (which is about 27", though there are some narrow-tire, 26" models.), 21 - 24 gears. Combine mountain-trail-comfort bike seating and handlebar position with wider tires on road bike diameter wheels.
Most have 26" wheels, 1 - 7 gears. Beach bikes, fat tire bikes. Usually heavier bikes with one speed and coaster, foot brakes, or multi-speed with hand brakes, wide tires, upright handlebars and seating position.
Most have 26" wheels on the mountain models, or 700C wheels on the hybrid, touring, road models, 1 - 27 gears. "Bicycles built for two" riders.
BMX and dirt bikes: Most have 20" wheels, 1 gear. Initials mean Bicycle Moto-Cross, a 1970's outgrowth of Scrambling or Motorcycle Moto-Cross (or MX) racing. One speed, usually have hand brakes, short wheelbase frames, knobby tires.
