Ergonomic Mesh-Back Seating
A comfortable workout is a productive one. That's why we developed an ergonomic mesh-back seating to give you unparalleled lumbar support and breathing. The seat and backrest are fully adjustable to meet your personal needs.
Wide-Platform Pedals
Keeping you comfortable keeps you on the path to a healthier life. That's why we made the Smooth UB4 more comfortable than any outdoor bike. The extra-wide seat disperses pressure, giving you a comfortable ride and extending your workout.
Ergonomic Mesh-Back Seating
The seat of the SB4 is unrivaled in comfort, lumbar support and breathing. Seat height and backrest recline are each fully adjustable.
Magnetic Braking System
SB4 semi recumbent exercise bike's resistance system has less parts, which decreases potential service issues.
Wide-Platform Pedals
You will pedal confidently on the oversized pedals of the SB4 exercise bike. The adjustable strap secures your foot and helps you produce maximum torque from your pedal stroke.
Body Fat and BMI (Body Mass Index) Calculator
Smooth SB4 semi recumbent exercise bikes feature a built-in sensor that calculates your body fat percentage when combined with your height and weight. The feedback you receive serves as an excellent guide to monitor your weight loss and muscle toning progress.
Easy-to-Use Training Computer with Two-Color Display
The stunning, two-color backlit display shows time, speed, RPM, distance, watts, pulse, pulse recovery, Body fat, calories and temperature.
Hand Grip Pulse Monitor
Ergonomically positioned for easiest possible access to heart rate data.
Five Heart Rate Control Programs
Based on settings you choose, the computer automatically adjusts workout intensity according to your pulse reading. Train at 55%, 65%, 75% or 85% of your maximum heart rate or key in the target heart rate you wish to match. By training in your target heart rate zone, you will derive optimal fitness benefits from each workout session.
Recovery Pulse Measuring
This is one of the most convenient and reliable ways to evaluate your level of cardiovascular fitness! At the end of your exercise bike session, press the recovery key and continue to monitor your heart rate for 60 seconds. The computer will calculate the speed at which your pulse returns to a resting heart rate after a workout. Based on this data, your fitness level will be scored from 1 to 6 (1 is highest).
Transport Wheels
Wheels to easily transport your machine to any room in the house.
Manual
Adjust the bike's resistance as you go for a 100% customized workout.
Preset Programs
The Smooth Peloton SB4 semi-recumbent exercise bike comes with 12 preset course profiles so you will never grow bored. Your course stage and intensity is displayed on the console and can be adjusted at any time during training.
User-Defined Programs
Design up to four rides all your own! You have the freedom to choose the intensity of each of 20 segments to the workout.
Heart Rate Control (HRC)
By positioning your hands upon the ergonomically positioned sensors, the elliptical computer varies the resistance according to your pulse. This will assure that the intensity of your training is maintained at a level that will benefit you.
Watt Control
The Watts program is designed to help you to exercise at a consistent performance level. The program defaults to 100W and can be adjusted according to preference. Resistance will be adjusted automatically to maintain output consistent with your watt setting.
Body Fat Testing
After keying in your gender, age, height and weight, press your hands to the pulse sensors and hit the START/STOP button. The computer will calculate body fat percentage, body mass index and basal metabolic rate (the number of calories your body burns while at rest). Based on this data, the computer will recommend a workout program for your body composition.

"I wanted a bike and didn't want to spend alot of money. I spoke to a sales rep who told me that this machine would be enough for a guy my size. I took a chance and am very satisfied. Assembly was a little harder than anticipated, but I got through it. Pay for inroom, it was worth it. Those 2 guys had a tough time getting it in. My experience was everything I could have hoped for."

"This is a very well built bike. I was a little hesitant buying something I never tried, but I am glad I did. This bike is everything I had hoped for and more. I needed this machine to be able to be moved on a daily basis, and the wheels on the front make that very easy. A great bike for those looking for a good one."
