This bike comes equipped with caged foot pedals that provide stability and safety.

Magnetic resistance uses magnets to add resistance which allows for smooth and quiet riding experience. Since it’s a magnetic brake and its pad doesn’t touch the flywheel, you won’t have to worry about wear and tear, replacement, or any friction-generated noise.

The durable belt drive provides smoother and silent pedaling and requires less maintenance.

The performance monitor helps track time, speed, calories, odometer, RPM, and pulse.

Feel confident sitting on our durable design with a 265LB max user weight limit.

Yes! The handlebars are 2-way adjustable (up and down) and the seat is 4-way adjustable (up, down, forward, backwards) for a fully customizable fit.

Bike is near silent and wheel runs smoothly. Sunny even has a collection of bike workouts on YouTube that I found to be fun and effective workouts.

This bike is built like a tank. I'm 5'6 weigh 245 pounds and this bike holds my weight well. We swapped out the pedals so we can use our SPD clip ons. Rides are quiet, resistance is smooth, and we've been enjoying working out again.
