Here’s how to approach the question: Bike style: Different riding styles require different bike styles, so your first consideration is where and how you plan to ride.
Key features: The biggies are suspension, wheel size, frame materials, gearing and brakes.
Fit: Last, but not least, be sure your bike fits you well.
This is best done in person at a bike shop like REI.
These bikes can be great if you’re considering getting competitive or would like a racier ride for your local trails.
