The bike seat is completely adjustable. It can be adjusted forward and backward and again up and down movement. So people of different heights can use it with comfort.

Coated Handlebars

The handlebars are padded and give a plenty of choice of a handgrip. It can be adjusted up and down only. It’ll offer you firm grip without blister or sore in your hand due to sweat. You can lean over the handlebars when you are out of the saddle.

Quite Workout Operation

You can hear only humming sound due to the friction of the resistance pad on the flywheel. Otherwise, it’s quiet. You can enjoy other activities along with your workout like- listening to music or watching TV, etc. Again it’ll not disturb neighbors in the apartment. So carry on your workout even at the mid of night without bothering others.


The pedal of the bike is with strap and toe cage. The strap can be adjusted, and it can hold any size of the shoes firmly without slipping. So If you are scared of slip of your feet during exercise, then this bike gives you relief. Also, the pedaling is smooth and hassle frees.

If you can paddle a bike properly, then it will help you to have longer workout session. It will increase your stamina and help you to challenge your strength.


The console of the Belt Drive Sunny Health SF-B1423 is simple and displays time, distance, no. of calories burned and speed. It doesn’t measure your heart rate or RPM. So, you will have perfect idea on measuring your current condition during workout.

The monitor comes with a basic control to track your progress. Simply get on the bike and start your workout and soon you’ll notice LCD screen displaying the reading. You can see the information from a comfortable distance.


The bike has friction pad which controls resistance level during the workout. The resistance level is increased or decreased by turning the tension knob. This Sunny Health & Fitness SF-B1423 Belt Drive will amaze you with the resistance system.

It’s easy to turn, and it doesn’t jump suddenly from lower level to higher level. So you can have a smooth workout in spite of the gradual increase of the resistance level.

This press-down braking system meets the need of a wide range of users. To stop the flywheel quickly, you have to push down the knob, and the pad will work as the brake. The pad will wear down on over time. So replace it periodically.

Belt drive and heavy flywheel

The SF-B1423 Indoor bicycle has belt-drive system and heavy duty flywheel weighing 40 lbs. So it offers consistent pedaling. They offer smooth, stress-free workout and noiseless operation.

The bike doesn’t wobble or shake during the intensive workout. Due to heavy flywheel, you can get the sensation of hard bike ride like mountain climbing.

Due to belt drive, you don’t need that much maintenance like lubricating or tightening like the case in chain-drive.

Stability & Safety

The frame, stabilizer bar, and heavy flywheel are responsible for stability and sturdiness of the bike. The frame and stabilizer are made up of heavy duty steel which doesn’t flex and offer long- term durability.

The drive is enclosed, so there is no possibility of being injured during the exercise. If the flywheel were exposed, it would be difficult to use it in front of kids or pet.

So the company has considered the safety of the bike and safe ride of the users at the same time.
