Stay at home Spin, yes!

Like everyone, I have been homebound due to Covid-19. I never expected to enjoy spinning in front of my TV; it turns out I love it. This bike is every bit as good as those at my gym. I never used a monitor, so I do not miss it. I use this bike nearly every day for 15-40 minute rides. Thank you for the excellent product.

Excellent Bike

I could not be happier with my Sunny Spin Bike!! I sold my first spin bike which had a 30lb flywheel and purchased this model. I am not missing my first bike at all. The 49lb flywheel and sturdy frame is excellent. For the price and the quality of this machine, you cannot go wrong.

Affordable, Study At home bike

Since receiving this item, the installation process was straightforward, quick and (relatively) easy. Took under 2 hours to put everything together. The bike itself is fantastic and is very smooth! I ride with the Peloton App and ordered the Wahoo cadence monitor and figured out the percent resistance based on the total # of turns to reach 100% resistance. Very happy with this purchase and looking forward to logging many rides on this bike!

Belt drive indoor cycle

The bike is extreemly quiet. It provides an excellent workout and adjust easily.Set up instructions are very easy to follow and took no time at all. I am also impressed with the workouts provided online from SUNNY. They also offer great advice for setting up your bike so that it fits you properly. Very impressed and I will definitely purchase from SUNNY again when I need exercise equipment.

Great indoor bike

Homeschooling 4 kids became too much for my sanity so we bit the bullet and bought this lovely bike so I could exercise without leaving the house (husband is in HC and works crazy shifts) and without waking everyone up. I have enjoyed the quiet ride, smooth pedaling, and was able to start exercising immediately after putting the bike together. You need two people to put it together due to the weight, but very easy instructions and the bike arrived really fast considering the COVID era we are in.

Love the heavy flywheel

This bike is great except that even on the lowest setting, it's not low enough for me (5'1''). I can ride, its just difficult when standing to push my hips back over the seat. The set up was super easy and it arrived very quickly (4 days after the order).
