Bicycle

An important first step in making bicycle commuting a part of your daily life is purchasing a bicycle or tuning up your old one. First you will need to determine what type of bicycle is best for you, based on your needs, preferences and environment. The tips below will help you get started, but you should visit a specialized bicycle shop to be properly fitted for a new bike.

Basic Steps to Buying a Bicycle

  1. Determine the kind of riding you plan to do (distance, location and likely conditions)
  2. Figure out the type of bicycle made for that kind of riding (comfort, road, hybrid, cruiser)
  3. Select the proper size bicycle (frame size and style)
  4. Test ride the models you have selected (be aware of seat and body comfort, leg extension, hand position, and any leaning or pressure you feel)
  5. Choose the bike that feels most comfortable to you (certain accessories can enhance comfort)
  6. Ride and enjoy your new bike (clubs, group rides, events, transportation)
  7. Keep your new bike adjusted and maintained (break it in, maintain tire pressure, keep it clean)

Bicycle frame materials: pros and cons

Steel:
Pros - Strong, cracks grow slowly, easily repaired, available in a variety of dimensions and alloys
Cons - Heavy (three times heavier than aluminum and twice as heavy as titanium), rust potential
Aluminum:
Pros - Light, inexpensive, tubes are available in a large range of diameters, wall thickness and alloys
Cons - Cracks grow quickly when they develop, leading to sudden failures. Harder to repair than steel, and requires a large diameter and/or thick walls to achieve adequate strength and stiffness.
Titanium:
Pros - Light, strong (weighs about half as much as steel but 25 percent more than aluminum)
Cons - Expensive
Carbon Fiber:
Pros - Light, strong and easy to adapt
Cons - Issues with reliability, especially joints and connections. Long-term exposure to UV rays may be damaging to the resins that bond carbon fiber. Breakages typically occur suddenly.
