If you are on a hunt for a first or new recumbent exercise bike, then you’ve probably noticed that there are plenty of options to choose from. One particular option that has received plenty of positive reviews is Sunny Health & Fitness SF-RB4708 magnetic recumbent bike.
This bike differs a bit from other recumbent bikes in one major function – the moveable handlebars. Otherwise it’s a pretty standard mid-budget machine. As always will we go through features, user reviews, pros and cons and conclusion.

Features of Sunny Health & Fitness SF-RB4708 Magnetic Recumbent Bike
Min-Max Seat Height
26.5" - 34"
Min-Max Handlebar Height
60"L x 25.5"W x 52"H
As we have already mentioned, the bike comes with moveable handlebars, which act as an arm exerciser, which can work synchronously with legs. This way you can achieve nearly full-body exercise.
The bike uses belt drive and magnetic resistance system with 8 different tension levels, so you can adjust the workout level according to your needs. Tension can be adjusted thanks to the conveniently located tension knob. Maximum weight support is set to 350 lbs (158.7 kg).
SF-RB4708 recumbent bike is equipped with extra large and cushioned seat and back-pad. Thanks to the rail system you can adjust the height along with the distance. Maximum inseam height is 36 inches and minimum is 29 inches.
The bike is equipped with a digital LCD monitor, which keeps track of basic stats like distance, speed, time, scan, calories burned and also heart rate, thanks to the hand pulse monitor.
The SF-RB4708 is also equipped with transportation wheels, located at the front bottom base.
The assembled dimensions are 60L x 25.5W x 52H inches (152.4 x 64.8 x 132.1 cm) and the empty weight is 94.8 lbs (43 kg).
Let’s start with the assembly. The manufacturer provides an instruction manual to put the bike together. While the manual could be clearer, it does the job and if you follow it properly you should have the bike assembled in less than 2 hours.
With that being said, you can assemble it faster if you have your own tools, like M15 and M13 wrenches, since the provided ones are pretty basic.
Rock-Solid Sturdiness Goes a Long Way
I’m pleased to say that most users are satisfied with the bike’s sturdiness. The frame is really heavy duty and 350 lbs weight support is totally believable in this case.
The motion of the bike is very smooth and thanks to the belt-driven system also very quiet. Do you plan on watching TV while exercising? Not a problem with SF-RB4708 magnetic recumbent bike.
The magnetic resistance system can be conveniently switched from one level to another. However, several users reported that there is very little tension difference between the first 4 levels.
The moveable handlebars are connected with the pedals, however, if you would like to exercise just your arms, you can simply put your feet on the floor. Several users reported that it works like a charm.
The back-pad and seat are bit oversized and quite comfortable. The lever for adjustment works very smoothly and is user friendly. Since there are no lock-positions, you can adjust the seat all the way from front to back and it will conveniently support users up to 6’6”.
Several owners also reported problems with pedals falling off; however, this seems to have been the problem of wrong pedal assembly. Make sure to follow the assembly instructions properly.
I also feel a need to point out that nearly all users who contacted Sunny Health & Fitness customer support were very happy with them. The company seems to really take care of their customers.

The Sunny Health & Fitness SF-RB4708 magnetic recumbent bike is a good choice for beginner and intermediate fitness enthusiasts. It’s a comfortable, sturdy and low-impact piece of machine. As long as you do not mind a bit painful assembly and not-so-many tension levels, I don’t see a reason why this shouldn’t be your recumbent winner.
