FAQs

The Product Manual may be downloaded below. If you have any questions, please feel free to contact our customer care team.

The differences for the Synergy & Synergy Pro bikes are the weight of the flywheel, the type of pedals it comes with, and the weight capacity. Both models come equipped with the specially patented flywheel, magnetic resistance, dumbbell holders, along with a water bottle holder.

The innovative patented flywheel works in sync with its advanced magnetic resistance system and makes riding extra smooth, solid and quiet.

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

Feel confident sitting on our durable design with a 275 lb max user weight limit.

The performance monitor helps track speed, distance, time, calories, odometer, rpm, pulse, with a scan mode.

Yes! The Synergy Magnetic Indoor Cycling Bike comes with dumbbell holders so that your dumbbells (not included) are readily available for upper body & core exercise in tandem with your cycling workout.

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.

There is a 3-year warranty on the structural frame and 180-day warranty on other parts and components.

An outstanding bike for the cost. We also found free apps for workouts and I set up a smart tv so we can follow workouts and have found several on YouTube using Sunny equipment. We are extremely pleased with all aspects and thank you Sunny for making this bike. We considered a lot of different manufactures, but your equipment exceeded theirs for a lot less money.

Yara V.

It has been great! I never been a fan of spinning or cycling but I needed to do cardio exercise, especially now that I can’t go to the gym. My husband and kids are using the bike as well. It’s very quiet and a smooth ride. I’m using the "P" app and surprised myself as I’m really enjoying it, which is in great part due to the bike. I’m very grateful that the company shipped my bike as soon as possible, prior to temporarily closing shipping due to the COVID crisis.
