If there’s one thing that we know about exercise bikes, never compromise on the quality of product in order to save a few dollars. But what if you want to buy an indoor exercise bike and don’t want to spend a fortune on it? You either end up buying an inexpensive and low quality bike or you stumble upon this article in which we are going to review a well-made and durable bike that is not going to cause a bump on your bank account. We are talking about the SF-B901 by Sunny Health and Fitness which, due to its affordable price and practical use, has received a lot of positive feedback and is one of the top-selling exercise bikes on Amazon. It is one of the least expensive exercise bikes but a low price tag doesn’t always mean low quality. Let’s find out all about this bike and see what makes it the perfect indoor exercise bike for you and your family.

The SF-B901 Pro Indoor Cycling Bike, when assembled stands 46.5 inches high, measures 48.5 inches from its rear support bar to the transporting wheels on the front, sits 20 inches wide and weighs 108 lbs. with an exceptional weight capacity of 275 lbs. With such low price it’s fair to have concerns regarding the sturdiness of this machine, but don’t worry as the 40 lbs. flywheel and a well-constructed steel frame allows it to provide a smooth and steady work-out without any turbulence at all.


The first thing that catches your sight when you look at this bike is its bright red 40 lbs. flywheel which is the heart of this machine. Its chain drive mechanism is intended to provide the kind of smooth resistance that conventional outside bicycles do. Now chain drive may be a little noisy and might need maintenance but proves to be more long lasting.

Moreover, this bike comes with a wide range of resistance from low to high. Unlike most exercise bikes, the knob settings on this bike are not marked. Resistance is adjustable by simply turning a knob in one direction to increase it and other to decrease it, so in order to find the best suitable resistance setting for you it might take a little getting used to. The knob simply tightens or loosens a two felt brake which is placed on the top of flywheel to control resistance. With the knob there is a lever that you can push down to stop the flywheel and pedals to move so you can safely dismount the machine.

The handlebars on this bike are thickly padded for a strong grip and are horizontally adjustable. Now normally somewhere around the handlebars you’d find a console but this bike disappoints in this area. It does not come with any kind of console. This hasn’t bothered a lot of consumers who are looking for a hard work-out for a specific period of time but if the work-out data (time, distance, speed, calories burned) is valuable to you, it can be fixed by buying a portable console.

The seat provided with this bike is not made to provide comfort and has received a lot of complaints, but this issue can be fixed by adjusting the seat to your comfort and if that doesn’t help you can always buy a separate gel cover for the seat. It can also be replaced with any regular bike seat. The horizontal adjustability settings for the seat make it ideal for people of different height ranging from 5 ft. 1 inch to 6 ft. 2 inches.

This bike comes with regular pedals including toe clips and straps. Owners can fix any standard bicycle pedals with the frame. The toe strap can also be adjusted to allow different shoe sizes for when you change your shoes or when there is more than one user. Thanks to the heavy duty crank these pedals are attached with, you don’t have to worry about breaking the pedals even while cycling standing up.

Lastly, it is provided with transportation wheels so you don’t have to worry about moving it around your house and scratching the floor with heavy steel.


When you get the bike it comes almost assembled. The assembly is quite straightforward. The directions can appear to be complicated as the manual is not very user friendly and lots of parts are listed making it look like a huge deal to assemble the machine, However, you just need to affix a couple of parts and once past this part the manual is easier to follow. The bike can normally be assembled in 30 to 60 minutes. The bike comes with a 1 year warranty for its frame and a 90 days warranty for parts.


  • A very good price to value ratio with quality as good as more expensive bikes.
  • Easy to assemble.
  • Front mounted transport wheels making it easy to move.
  • Even with a chain drive mechanism this bike is quiet enough so you can listen to music or watch T.V while working out.
  • Smooth and sturdy work-out even while standing up.
  • Not a lot of maintenance required except lubricating and changing the brake pads every now and then.


  • Uncomfortable seat.
  • No console to monitor performance.
  • Handlebars can only be adjusted horizontally, sometimes making it difficult for users with short height.


Indeed, the Sunny Health and Fitness Pro is denied of some hi-tech features, however when you are getting a bike with a 40-pound flywheel and numerous other intriguing features at a bargain price, there isn’t much room for grumbling. It’s a bicycle for both starters and advanced users looking for an intense spinning experience. Practically identical in quality to considerably more costly bikes, this bike is the exemplification of uncomplicated design, and is a perfect choice for anyone on a budget looking for a basic bike.
