Indoor bikes closely resemble that of a road bike, allowing cyclists to replicate the experience of changing gears via use of a dial. Popular with both home and commercial gyms, and whether you're a seasoned cycling enthusiast or a beginner, indoor bikes are a fantastic choice for supplementing training and can be used year-round, regardless of weather conditions. The option to pedal the bike standing up also provides an opportunity to train muscles harder, generating more power and building endurance.
