How to choose an under desk bike from Sunny Health & Fitness
Consider the resistance type first. Motorized models provide assisted pedaling and often include preset programs, which can be helpful for rehabilitation or gentle movement. Magnetic resistance offers quiet, manual tension control with consistent feel. Stepless resistance gives infinite adjustment but no fixed levels.
Think about stride length. Longer strides (e.g., 7 inches) provide a fuller leg movement, while shorter strides (4 inches) keep pedaling compact. Portability is key if you plan to move the bike between locations; lighter models with carry handles are easier to transport. App connectivity adds tracking and guided workouts via the SunnyFit App.
Finally, consider additional accessories like resistance bands or mats included with some models. These add upper body workout options without extra purchases.
