Sunny Health & Fitness Magnetic Rear Belt Drive Indoor Cycling Bike, SF-B1709 Overview

Sunny Health & Fitness makes excellent quality fitness equipment to help you realize your fitness goals. This Sunny Health & Fitness indoor cycling bike is quite emblematic of the quality and reliability that you would expect from this brand. The SF-B1709 is a unique and nicely built spin bike. Customer ratings are, so far, largely positive.

Unlike other spin bikes that we have reviewed, it has an ultra-lightweight flywheel that enables you to spin at lighting fast speeds. As you will see, however, that lightweight flywheel isn’t a hindrance to its performance.  This spin bike has some extra tricks up its sleeves. Read on and find out.

It makes up for the very light flywheel, just 7lbs, with an adjustable magnetic resistance system that you can use to change the wheel’s magnetic field resistance to get a smoother and more responsive ride. Obviously, you get faster spins with this spin bike than with a traditional heavy flywheel spin bike. The faster spins, combined with the magnetic resistance field, create a variable centrifugal force that gives the smaller flywheel as much weightiness as you would get with the larger 30lb, 40lb, or 40lb flywheels.

Its belt-drive system gives you a super quiet and resilient performance. You won’t have to worry about this spin bike annoying neighbors or your housemates when you are taking it through its paces and ramping up the adrenaline.

The magnetic resistance is just sufficient to pose a real fitness challenge. Don’t underrate the small flywheel. You will have to be superhuman to peddle at ultra-high speeds with the magnetic field resistance set to the maximum value. The resistance level is quite impressive. This in spite of the fact this spin bike doesn’t entirely lock peddles in place for good stability. Besides, its smaller 7lb flywheel is easier to stop than a larger 50lbs flywheel.

The Sunny Health & Fitness SF-B1709 features a small multifunctional display that records and shows the fitness parameters including speed, average speed, cadence, max cadence, calories, distances, time, and race. It offers you a good detail of metrics and information on your biking sessions.

It scores highly on the looks department, too. This is a spin bike that is well made and which looks really good. It is a nice-looking piece of equipment for indoor cycling.
