Choosing the right bike means finding the best fit for your riding style, terrain, and goals. Road bikes prioritize speed, mountain bikes handle rough trails, gravel bikes offer versatility, and commuter or folding bikes suit everyday city riding. This bike buying guide will help you compare bike types and choose the right bicycle for your needs.

Start with the riding environment and comfort you need. There is no single category that is automatically best for every beginner.
Choose a road bike if most riding is on pavement and efficiency matters. Choose a mountain bike if rough terrain and trail control matter more.
It can be a strong all-round choice for riders who mix pavement, gravel and longer-distance riding.
Use height as a starting point, then verify the exact geometry and size chart for the specific model.
