Hi Mike - Best advice I can give you is to buy a bike from a real bike shop. Stay away from places like Walmart.
A bike is a vehicle that requires regular maintenance, plus proper setup for it to be reliable, enjoyable, and safe. A good bike shop will save you money in the long run.
Learning how to properly maintain your bike yourself isn't difficult, but doing it right is essential. The bike shop can help you make the right choices. Here's a good shop in your area:
Performance Bike
If you get a bike, the two most important things you can do to keep it running smoothly are:
1 - Check tire pressure before every ride (which means you'll need a good pump with a pressure gauge - like
this)
2 - keep your drivetrain clean, and your chain lubed properly. A chain cleaning machine makes this easy.
This one works well. You'll also need some good lube, like
this.
Here's a good
video on how to clean and lube your bike.
Good luck, and don't forget to get a good fitting helmet!
