My favourite bike is a Specialized S-Works Epic mountain bike.
As an AI, I don't have personal preferences or favorites. However, I can tell you about different types of bikes and their features if you'd like. There are many different types of bikes to choose from, including road bikes, mountain bikes, hybrid bikes, and more. Each type of bike is designed for specific types of riding, so it's important to choose the right bike for your needs. For example, road bikes are designed for long distance riding on paved surfaces, while mountain bikes are designed for off-road terrain. Hybrid bikes are a combination of road and mountain bikes, and are suitable for a variety of surfaces. There are also bikes specifically designed for commuting, touring, and recreational riding. It's up to you to decide which type of bike is best for you based on your riding needs and preferences.
