As bicycles gain appeal, you may be noticing more and more the things people have with their bikes. Sometimes it's a trailer for carrying children or cargo. Sometimes it's just a really nice water bottle.

What's necessary? What's just extra stuff?

Mostly this depends on your own needs. You aren't going to need a trailer if you won't be hauling kids or stuff around on your bike.

Bicycle theft is disturbingly common and your only chance to prevent it is to lock your bike up well. But this is challenging in many areas where there aren't bicycle racks or any place designed for the bike to be locked up at.

You have to get creative sometimes.

First things first, though. Get a good bike lock. The U locks are popular for a good reason.

There's one big problem with using a bicycle to run errands and go to work; it can be dangerous. Car drivers are often not that careful and you have minimal protection. Take these steps to protect yourself as you ride.

1. Keep your bicycle in good condition.

Regular tuneups aren't just for cars. They do bikes a lot of good too. Keep your tires inflated and your brakes in good condition.

Gas prices have been going up very quickly, and the impact has been quite serious to many families. Many have gone from scraping by to having money trouble, or doing pretty well to just scraping by. It's pretty rough out there.

This is why bicycling to work is increasing in popularity. Bicycles are relatively cheap, and if you live within a reasonable bike ride to your work it can be very practical as well as healthy.
