SF-B901 Frame and parts

Sunny Pro Indoor Cycling Bike

The steel-made frame of the bike is very sturdy, offering superior stability when working out. So even if you’re a taller or heavier user, you shouldn’t worry about falling or losing balance. Since it’s not an exceptionally delicate piece of equipment, it does come with transport wheels on the frame’s front base.

The bike isn’t too sizeable. It’s only 48.5″ in length and 20″ in width. Therefore it should fit almost any room unless you’re tight on space.

The handlebar is vertically adjustable and generously padded with foam, offering a good grip even when your hands are sweaty. In addition, the design of the handlebar provides various holding possibilities. For example, you can adopt a forward, steep leaning position or work out in a nearly upright position.

The seat is 4-way adjustable. It can be moved from back to front and even vertically. It comfortably accommodates users beginning at five feet (152cm) and up to 6’5″ (195 cm) tall. On its lowest setting, the distance between the seat and the lowest to the floor pedal is 32.5″  (82 cm).

Pedals are anti-slip and come with straps that help fix your feet in place. In addition, they’re sturdy enough to allow stand-up training even for heavier users.

SF-B901 Resistance

Like most indoor cycling bikes, the Sunny SF-B901 offers the highest-intensity workout possible on a stationary bike. The flywheel weighs 40 pounds, enhancing the bike’s stability and rendering the exercise pretty smooth. The brakes are direct-contact, featuring two brake pads that close laterally on the flywheel.

There are no specified tension levels on the resistance mechanism of the bike. Resistance is adjusted onto the brake pads from nearly no resistance up to the impossibility of pedaling. Resistance modification is manual, but you can do this while pedaling.

Therefore, even if there aren’t any “clicks” on the adjustment knob, you will know when the setting is suitable for your training.

SF-B901 Assembly and Maintenance

The assembly of this Sunny SF-B901 is far from confusing. Some of the parts are pre-assembled. For example, the flywheel comes attached to the frame, with the chain and the crank arms connected. The bike sits on narrow bases for shipping, which needs to be removed and replaced with the bike’s standard bases.

So, all you’ll need to assemble are the seat and handlebar posts, the seat and handlebar themselves, the bike’s bases, and the pedals. Therefore, it shouldn’t take more than 30 minutes of your time. Also, the box includes the tools you need for the assembly and the instructions manual.

In terms of maintenance, the Sunny SF-B901 does not require much. The brake pads will last for years, even with a few hours of daily use.

If the brakes begin to emit squeaky noises, you must apply powder graphite to the brakes or silicone spray. Or, if they wear out, they may require replacement. If the chain becomes squeaky, spraying a bit of grease on it should do.

  1. I am looking for a good-quality cycling bike at an affordable price. During this quarantine, I have been a bit more relaxed concerning my diet (since I stayed at home). But now that I want to get back on track, I know that I need to exercise. And Sunny SF-B901 seems to be a good match for me.

  2. It seems to be a great product based on this review. The Sunny Pro Indoor Cycling Bike is a must for everyone, especially in this lockdown time. I have read your review and found this to be very useful. The only con is that there is no tracker, but that is not a big issue because nowadays, everyone tracks their workouts on their watches! Moreover, such built-in trackers with the cycles only increase the price. So it’s good not to have that and instead use your watch to track the workouts! Great product and fantastic review that covered all the points. It has helped me a lot to make a decision. I will seriously consider buying this. Thanks!

    • Hi Augustine, thanks for stopping by. If you have any other questions about the Sunny Pro indoor cycling bike, please let me know. I’d be happy to answer them.

      Kind regards, Robert
