What does that mean? What do you mean by a four cycle bike? I have never heard of anything like that. Are you talking about a four speed bike? I have no idea if you are referring to a bicycle or a motorbike. If you are looking for a good bicycle then there are several options that you can choose from. Cross country cycles have more than four gears and they are very useful for losing weight and staying fit. Bicycling is an often underrated and underused aerobic exercise. You can choose from different brands according to your needs. Cheers!
