Sunny Smart Programmable 16 Levels Electro-Magnetic Resistance Recumbent Exercise Bike

The Sunny SF-RB4855SMART provides a step-through design, adjustable seat, and quiet belt-drive system. Its console and app integration allow users to select from various resistance levels and programs to match their preferred cycling style.


Sunny Smart Programmable 16 Levels Electro-Magnetic Resistance Recumbent Exercise Bike

Key Features & Benefits

  • Electro-magnetic resistance (16 levels)

    Lets you fine-tune how challenging your ride feels, at your pace, with precise digital control for smooth transitions.

  • Quiet, belt-drive system

    Operates with minimal noise and little upkeep, so your focus stays on pedaling—not the machine.

  • Easy step-through frame & adjustable seat

    A low-access design plus a sliding, padded seat makes getting on and off hassle-free and allows riders of different heights to find their fit.

  • Smart console with SunnyFit app

    Bluetooth connectivity allows pairing with the SunnyFit app for access to guided sessions, scenic routes, and real-time tracking.

  • Convenient pacing tools

    A tablet/phone tray, water bottle holder, and seat-level pulse sensors make tracking your ride seamless and your essentials within reach.

  • Mobile design

    Built-in transport wheels let you glide it from room to room—no heavy lifting needed.


Console and Programs

This bike includes a user-friendly console with:

  • Clear display of time, speed, distance, RPM, calories, heart rate, and wattage

  • 24 preset programs for varied riding - including BMI, target heart rate, and wattage tracking

  • With Bluetooth connectivity for use with the SunnyFit app, which provides guided sessions, scenic routes, and performance tracking.


User Interface & Experience

Sliding into place is easy thanks to the step-through frame. Adjust the seat until your legs reach the pedals just right, secure your feet with the straps, and start your ride. The belt-drive operates quietly, and the resistance adjusts smoothly when the intensity is changed.
