Recumbent Fitness Exercise Bike

If you have a bad back this is probably the exercise bike you should be looking to buy. The Recumbent Bike will have the seat closer to the ground and the pedals in front of you so your hips and knees are at the same levels. This will take the pressure off of the lower back.
The gauges that you will find on these bikes are the same as the upright bikes and include a LCD screen that will show Speed, Distance, Time, Fat Burned.
Recumbent Bikes are manually powered unlike Treadmills and require human energy to turn the pedals. Most recumbent bikes use “Magnetic Resistance” that can be increased or decreased to whatever tension you want. They also come with handle bars either in the front or back usually the latter which will help you bare down harder if you have increased the tension. 
Most of these Bikes will have an adjustable seat or bar that will regulate the distance between the pedals and seat. The seat on the recumbent bike is different than that on the upright or indoor cycle because it is usually flat on the bottom and has a back rest just like a chair and that’s why they are so comfortable to ride.
The footprint on the recumbent bike will always be larger than that of the Upright Bike. Make sure you know the exact footprint of the bike and the location in your home you want it to be. The Recumbent bike will be similar in width to the Upright bike but they are usually longer and take up more space.
