You won't regret it!

So far I am extremely pleased with this bike. The feel and quality is definitely a lot better than the gym bikes. The seat can be uncomfortable in the beginning but it does get better over time!! Get this bike!! You won't regret it!!

Match made in heaven

I love my Sunny!! I've been spinning 4x a week using the Peloton app and it's been pure bliss. Match made in heaven for sure!

Great bike and affordable

Great bike without the high price tag. My wife and I are very happy we went with this bike over others.

Poor quality

Bought this bike in October. Within the first 2 months of not quite daily usage by 2 people, a pedal broke and the belt started shedding material, fraying, and causing loud noises when pedaling. Replacement pedal was sent, which then broke again in about a months time. Disappointing, since other reviews seem to be happy with the bike, but I can't recommend this product based on my experience. I will say that customer service has been good. They are supposed to send a new frame to address the belt drive issue, I'm just not confident that the replacement part will be any better.
