Incredible Value

I wrote a review on this bike, but it seems like it didn’t post. This bike is incredible. Sturdy, easy to assemble, super quiet and rides like a dream. I have wanted a spin bike for at least 6 months, but have been using a trainer. The problem was I was burning up tires and need constant tune ups. I finally decided on this one and WOW! This thing is built like a Sherman Tank and is better than the bikes at the gym. I didn’t want to spend $2000 on one of “those” bikes and I’m glad I didn’t. This one will no doubt last for years and is equal in quality. If you’re looking for exceptional quality at a lower price don’t hesitate. I’ve been riding indoor and outdoor bikes for a long time and this one is exceptional. I am one happy customer!

Solid bike! Way better than expected.

Ordered bike and even with the COVID-19 delays, it got here fast (less than 10 days). I normally ride a high end spin bike at my gym and I was amazed how this bike rode. Much more solid (I am 6'2 and 260). It does not wobble and the resistance is great. No odd catches when turning the dial. Very happy. I got the Peloton app and added a phone holder to the top so I can do spin classes at home. Also added clip pedals so I can wear my bike shoes. WAY cheaper than a Peloton bike. Super solid and a great ride. Would highly recommend.

it makes a lot of noise

the left pedal and the flywheel make a lot of noise. I thought maybe it needed to be broken in, but that has not stopped the noise from these.

Unhappy camper

Though the built is great quality I had issue with aligning the handlebar post to the seat height, the handlebar post sits way too high. The lowest handlebar setting does not align with the lowest seat setting. Unless you are a tall person, this will not have a proper fit for you. Buyers beware.

Sunny Health and Fitness

Hello David! Thank you for bringing this to our attention. We sincerely apologize for your experience. We see that a team member has been in contact with you via email and will in be touch with you shortly. Thank you for your patience and understanding!

I researched all kinds of equipment before purchase. I expected this one to be suited for long term use. I expected it to be quieter than other brands. To be smoother and better able to hold up to heavy use. I did not foresee that it would exceed my expectations by so much. It is heavy duty, gives a great, smooth, silent ride for a long as you can take. I'm more than impressed, I bought another piece of equipment from them and I can't tell you anything better than that.

DISAPPOINTED! Customer service provides NO Service

This bike is great....EXCEPT it doesn't have a performance monitor! I could have spent half the money and gotten a bike that measures distance, speed, etc. When I call customer support on two different occasions, I got two different answers! One person said there's an app to download that works with this bike; the second person NO there isn't. He suggested I buy a monitor from Amazon.... but doesn't know which one is adaptable. NOT HELPFUL! I may just pack it up and send it back even though the bike is great, I need that feature which is not available! Obviously, they are not there to help.
