Both the Sunny Health & Fitness SF-B901B Pro and SF-B1002 are impressive spin bikes for such a low price and offer excellent value for money.
The Sunny Health & Fitness SF-B901B has a slightly-lower price tag than the SF-B1002, mainly due to the fact that it has a lighter flywheel compared to the SF-B1002. Both flywheels are still considered to be heavy-weight and impressive to find on spin bikes at this price point, but the SF-B901B’s flywheel is 40 lbs compared to 49 lbs for the SF-B1002. A heavy flywheel on a spin bike is important because it is better at producing smoother consistent momentum than a lighter one.

You can adjust the intensity of your cycling workout with both of these Sunny spin bikes, as each has an adjustable resistance and push-down braking system. There is however a difference in the design of these systems between the 2 bikes – the Sunny SF-B901B has an adjustable tension-knob with a push-down brake lever, whereas the Sunny SF-B1002 push-down brake is incorporated into the adjustable tension-knob. Both systems are easy-to-use and give you total control over the intensity of your cycling workout.
Both the Sunny Health & Fitness SF-B901B Pro and SF-B1002 Indoor Cycles are fully adjustable for a custom fit to suit a wide range of riders – the saddle can be adjusted both up/down and fore/aft, while the racing-style handlebars can be adjusted up/down.
Useful tip: Just a 30 minute cycle ride could burn approx. between 207-345 calories for women, or 252-420 calories for men, depending on the intensity of the cycling.
