Sunny Health & Fitness SF-B901 : The Economical Upright Bikes

The Sunny Health & Fitness SF-B901 uses a 40-pound chain-driven flywheel to deliver smooth resistance that mimics an ordinary outdoor bike. This stripped-down, no-frills bike provides exercise excellence that is easily the equal of any other indoor stationary bike. The manufacturers have kept the price low by trading fancy add-ons for a sturdy frame, pedals and working parts. If you just want a good bike that will allow you to exercise in the privacy of your own home but don’t want to drain your financial resources, this is an excellent choice.

Bring Your Own Add-Ons

If you want those little extras like workout tapes, video or monitors, you can easily add them on later by purchasing music, fun audio scenarios, and measuring equipment – just as you might for an outdoor bike. Items such as the Fitbit Flex2 or the Letscom Fitness tracker can keep track of your speed, distance, time and heart rate, and can be used for other fitness activities, as well, preserving the money-saving aspects of the Sunny Health & Fitness SF-B901 while adding a little extra convenience and information for your day.

One of the complaints about many other indoor exercise bikes is that they are noisy. If you live in an upstairs apartment or even in a duplex, you’ll appreciate the Sunny Health & Fitness SF-B901’s very quiet operation. You can not only enjoy the comfort of exercising out of the weather and away from prying and sometimes hypercritical eyes, but you can confound the neighbor who pounds on their ceiling (your floor) every time you walk from one end of your space to the other by having a quiet exercise machine.

Upright Bike that is Easy on the Budget

Besides being a quiet, efficient workout machine, the Sunny Health & Fitness SF-B901 is easy on the budget. Since the manufacturers focused on good materials and workmanship, rather than on electronics, it is made of sturdy metal. Better yet, it is priced with the working class person in mind. Whereas many exercise bikes can cost well up into the thousands of dollars, most sellers offer this one at less than $300. It also takes up very little floor space and has wheels on the back leg to make it easy to move to one side when not in use. It also features sturdy pedals that can use clips or toe straps. If you wish, you can even add your own custom pedals, although one user recommended if you want to do that to add those pedals during the first assembly as it is difficult to remove the regular pedals once they are installed.


The Sunny Health & Fitness SF-B901 is a good machine, make no mistake about that. But like all good things, it does have some downsides. One of the biggest drawbacks is the warranty, which is not included in the purchase price. You can add it on for a modest sum, but its coverage is not all that great. If you love your tech toys for exercise time, you can look forward to adding the purchase cost of those for your home or office workout center.

Just to summarize, these upright bikes from Sunny Health & Fitness offer an economical way to stay in shape during inclement weather or for those who are more comfortable taking their exercise in privacy. You do have to purchase your electronic monitors, entertainment, and incentive recordings separately, but that gives you the opportunity to individualize your add-ons. That means you can tailor them to your tastes and needs. Finally, that warranty might not be all that great, but the trade-off for what you are giving up in the way of frills is an exceptionally sturdy machine with a minimal number of parts which means less repair time and more quality riding time.

So whether you like sweating to the oldies, running from packs of zombies or just zoning out to a good book, we believe that you will like this sturdy, quiet indoor exercise bike. You can buy more expensive bikes with exercise coaching built-in. You can buy the best spin bikes with fancy monitors. You can even purchase bikes that will keep you entertained while you pedal, but you aren’t likely to find one with this kind of quality for an equally economical price. It is a pleasant surprise to discover that Sunny Health & Fitness stripped away the non-essentials to focus on just plain good materials and workmanship.
