Choosing a new or used road bike can be an extremely daunting task what with the myriad of bike frames, materials, and component sets available not to mention the hundreds of different bike manufacturers.
At a basic level your choice should be defined by your needs, the ultimate fit of the bike, and of course your wallet.
In the first instance pay a visit to your local bike dealer.
You can normally tell a good bike dealership by how knowledgeable their employees are and how interested they are in helping identify the right bike for you.
Have in your mind the type of cyclist you aspire to be whether that is a fair weather rider, a commuter, or racer.
The staff at the dealership should encourage you to talk about your cycling goals, what your experience has been up to now and ultimately be able to measure you correctly for a new bike.
If you feel that there is a general lack of interest at the dealership do not be afraid to take your business elsewhere.
Ultimately your relationship with the bike dealer will become a two way street.
They will obviously benefit from selling you a great bike and if you feel you have received a great service then you won't hesitate in taking your bike back for repairs and general maintenance.
Don't forget about the other benefits a dealership can offer where you will be able to meet like minded cyclists who will hopefully be able to share their knowledge of local clubs, races, and on line resources.
Top level bikes can cost anything from $500 to $7000 and more.
You can of course buy a $100 bike from a big box store but I wouldn't recommend it for anything other than a casual ride around your local park.
These particular bikes will no doubt fall apart the first time you attempt any form of serious riding.
You can also find great deals on line but there is nothing like being able to take your future bike for a bike ride and examine it up close.
My advice is to set your budget to $500 to $1500; you will get a great bike at this price.
Remember to keep a little back, say ten percent, for the all important safety gear you will need.
It is very easy to spend more at this stage especially when you look at the great light weight frames and component sets that are available.
If you are starting out however, you may find yourself carrying a few extra pounds so it is cheaper to lose the weight first prior to buying a light weight bike.
Finally remember the bike warranty.
Most bike manufacturers are great in honouring the bike warranties but remember only defects in the equipment will be covered not any damages sustained as a result of a crash.
For that you can buy a "crash replacement" warranty where frames are often replaced cheaper than their retail prices.
Frames can come with a five to twenty five year warranty and in some rare cases a lifetime one.
Warranties for most components only last a year.
