Sunny SF-B1509 Premium Indoor Cycle Review

Last Updated on July 3, 2021 by Jeff

Sunny Health and Fitness SF-B1509 Indoor Bike Overview

Sunny Health and Fitness SF-B1509 Premium Indoor CycleThe Sunny Health and Fitness SF-B1509 Premium is in the middle to higher price range of indoor bikes for this brand. With a 40 lb chromed flywheel and a belt drive, this is a durable, quiet bike that will give you gym quality without the gym price tag. The pedals have two options—you can either use them as caged pedals for regular shoes or clicked-in pedals for cycling shoes. Adjusting resistance is easy with just a twist of a knob, and the step-down braking system lets you stop quickly and safely.

The padded seat and handlebars are both adjustable making this the perfect bike for an active family to share. The frame is steel and comes in white with red accents or pink and white at a slightly higher price.

Shipping and Assembly

Shipping might be free depending on the seller. Even if shipping is not free, the added expense might be worth it as this is a fairly heavy bike in a bulky box. You should be able to find free shipping though, as there are plenty of sellers for Sunny Health and Fitness equipment.

Assembly is very easy with much of the work already done. Some people had problems with the crankshaft assembly but usually figured it out without a lot of struggle. Average assembly time is less than 1 hour. All parts and tools are included in the package.

What we Love About the Sunny Health and Fitness SF-B1509 Premium Indoor Bike

Workout Versatility

Sunny Health and Fitness SF-B1509 Premium Indoor Cycling BikeThe ability to go with light resistance for speed sprints and heavy resistance for long, steady state rides in the same workout is awesome. Most trainees will benefit from varying their sessions from day to day. This bike can take you from beginner to advance as you change up your abilities and push past your own comfort zone. Advanced trainees can challenge themselves with high intensity interval training, also known as HIIT workouts. Intervals are not only great cardio, but can help improve stamina and make the workout more engaging.

Adjustable for All

Trainees that share equipment with others may sometimes have to sacrifice their own comfort because it is too big or too small for them. That is not the case with the SF-B1509. Adjustable at the seat in four directions and the handlebar in two, different sized trainees can use this bike without giving up their comfort or their form in the process.


Trainees that are working toward a goal with a road bike and using the indoor bike on bad weather days will appreciate the ability to use cycling shoes and clips to ride this bike. Adjustable foot cage on one side and bike clips on the other, there are very few bikes with pedals this versatile.

What Isn’t so Great


It is shocking that this bike listed as a “premium” model would not have the standard Sunny Health and Fitness warranty. The company offers longer warranties on the frame at both the lower and the higher pricing points.

MonitorSunny Health and Fitness SF-B1509 Premium Indoor Bike

Another big shock was the lack of even a basic monitor with this bike. At around $350 you would think a monitor would be included, but it is not. Most people would find this to be okay as they can use their own heart rate monitors and phone apps to track their progress.

How the SF-B1509 Compares to the SF-B1509C Model

Both bikes are in the middle to upper price range. The SF-B1509C model is around $10 more expensive. Both have the 40-pound flywheel and micro adjustable knob. Both have the two-sided pedals and the step-down braking system. The SF-B1509C has a chain drive which some prefer over the belt drive because it feels like a road bike. Others prefer the belt drive because it is quieter and smoother.

Final Word on the Sunny Health and Fitness SF-B1509 Premium Indoor Exercise Bike

We like how sturdy this bike is even during stand-up sprints at all out speeds. At 108 pounds, we were afraid that it would be difficult to move, but the transportation wheels are perfect and it is not a problem to push it back out of the way when our workout is over. The fact that we can adjust the seat, handlebars and resistance levels with just the twist of a knob is also a huge plus. We love that we can use this bike and that others in our family can use it as well.

The pedals are interesting and while not all trainees will have clip-in cycling shoes, the fact that the option is there is a huge plus. Overall, this is a great exercise bike with solid construction and a great design.
