Before making a final decision on purchasing a stationary bicycle, what is the most advisable next step for Warren?

Trying out both models under similar conditions is the most advisable next step for Warren because it allows him to directly assess the comfort, functionality, and overall experience of each stationary bicycle. By testing the bikes, Warren can evaluate how each model performs in a setting that mimics its intended use, ensuring that he makes an informed decision based on personal preference and usability. This hands-on approach can reveal differences in features that may not be apparent from reading specifications or reviews alone, such as the feel of the seat, resistance levels, and stability during use. This practical experience is crucial in determining which bicycle best meets his needs and preferences before committing to a purchase.
