The resistant knob on this bike is a simple turning system to adjust it.
Too many times do companies put a scrawny seat on. What I like about this bike is that it has a large seat. This one is made with 20% more steel to give it the strength to hold up to 400lbs. The Exerpeutic Gold 575 XLS is the heavy-duty version of their other upright magnetic bike. Exerpeutic has come to the rescue with this 400-pound capacity exercise bike that is not only affordable but quite a nice piece of equipment. Well in an affordable price range that is. High weight capacity exercise bikes are rare to find once you get around the 400 pound capacity mark. Spin bikes are the type for people wanting to simulate real road bike cycling. Uprights are the most popular type while Recumbent bikes are great for bigger people as they allow you to sit comfortably.
A heavy-duty exercise bike frame is a great foundation for holding heavy weights. This can be a reflection of the quality of the frame of the bike.
