The Sunny Health & Fitness SF-B901 has fully adjustable seat, so it makes using the bike in a multiple user family less stressful. Unlike most exercise bikes the weight capacity is only up to 275 pounds so users should be aware of this limitation before purchase. This is otherwise a worthy bike to consider. It delivers an invigorating workout but has the ability to do so quietly.
This unlike other models is actually easy to assemble (can be done in about 20 minutes). The wheel spins smoothly and it has good resistance. The quality of this spin bike is surprising and with the 40-pound flywheel it gives a good workout. This is a durable and very sturdy that will give uses the workout desired. It's comfortable to use in seated and in standing riding positions.
This is a heavier bike so moving it from room to room is probably not going to be something users will want to do once it is setup.
The Bottom Line:
The Sunny SF-B901 is an affordable alternative to taking expensive spinning classes. You can have it at home that allows you to exercise on your own time. It's quality-built and is relatively quiet and easy to assemble. This is not a bike for someone who appreciates all the bells and whistles other exercise bikes come with it is recommended for those who want to have a smooth riding and comfortable bike to have at home.
