Hi, I'm a complete beginner, and don't know how to ride a bicycle. On my way to buy my first one to learn and use it for 1-2 miles trips from my home. Do groceries, go to library, etc. Plan on using it for longer trips after i get used to it.

General tips? Recommendations on what type to buy? (Was planning on a fitness hybrid). Wheel size? Frame? Material? Should i just buy anything because it's my first bike?. Was planing on buying the typical "Walmart" bike. Looking for the cheapest (<$100).

I'm 25 age, male, height 5.9, weight 154 pounds.

Thanks for your attention and have a good day.
