Ultimately, your decision should be based on your financial situation, usage, and personal preferences. If you prioritize the latest features, customization, and are comfortable with the initial investment, a new bike might be suitable. On the other hand, if you want to save money, are open to a wider variety of options, and value cost-effective maintenance, a used bike could be the better choice.
Before making a decision, thoroughly research the options available, consider your budget, assess your riding needs, and if possible, take a test ride of both new and used bikes to compare your experience.
