Sunny Health & Fitness Indoor Cycling Bike (SF-B1805) Reviewed

It is no secret that the need for indoor exercise bikes is increasing every year. But if you are on a hunt for the best exercise bike, then I’d suggest taking a pause here and checking Sunny Health & Fitness indoor cycling bike, the model SF-B1805.

I don’t think that Sunny Health & Fitness brand needs a special introduction. They have been on the market since 2004, if I’m not mistaken and their main focus is producing exercise bikes.

Package & Assembly

Okay, first huge thing to note here is that Sunny Health & Fitness indoor cycling bike is heavy as hell. It weighs 139 lbs, so I tell you right now, have a buddy to help you out with it.

The assembly itself was pretty straightforward, though. It is doable by one person (despite the weight) and it should not take you more than an hour.

My Experience with Sunny Health & Fitness Exercise Bike

If you have the bike assembled and placed on the floor, it should be pretty easy from now on.

The construction is indeed sturdy steel and I believe the 300 lbs support is actually real. The magnetic resistance system is great and very quiet. However, once you go faster there will be a little humming, because of the vibration. This seems to be caused by the front wheel, so I’m not honestly sure if it’s fixable, although the sound is still pretty tolerable.

Thanks to the 4 adjustment seat levels, the bike can easily accommodate even taller guys. I can’t say this for sure, since I’m 5’10”, but I’ve read a review from 6’2” guy who mentioned the bike works for him just fine. Also the seat is quite comfortable.

The handlebars themselves are conveniently designed and have a tablet-holder. While they are adjustable, I believe the adjustment system from them could use better design, as I personally can’t imagine a 270 lbs person leaning forward onto them.

The pedals themselves are of pretty great quality along the straps. The straps themselves are of good quality material as well.

Pros and Cons


  • Sturdy steel frame
  • Steel pedals with quality straps
  • Comfortable seat
  • Seat adjust-able even for taller guys (6’2”)
  • Works with different apps
  • Tablet holder on the handlebars


  • Very heavy
  • The handlebars adjustment system could be designed better
  • Small vibration from the front wheel during fast rides

Our Rating: 4.3 Star Rating 4.3 / 5

Would I recommend Sunny Health & Fitness indoor cycling bike? If you do not mind mini-vibration and you are not 275+ lbs, then I’d say go for it. It is one sturdy bike that is worth its price, which, unfortunately, cannot be said about all the models on the market.

If you would prefer a cheaper bike, the I would suggest checking out Merax indoor cycling bike. Alternatively, if you are looking for something of a commercial quality, then the C505 spin bike by pooboo might be for you.
