"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."
Lillian A., Sunny Customer

"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."

The performance monitor helps track time, speed, calories, odometer, RPM, distance, and pulse, with a convenient scan mode. It can also connect to the SunnyFit app to display your metrics on your device as you follow along with the workouts.
Feel confident on our durable design with a 265 LB max user weight limit.
