Sunny Health & Fitness Bike

I use this bike every night for the past 3 weeks. It's easy to use and feels safe. I like my HIIT workouts and can pedal while standing without feeling like the bike will fall apart on me. I appreciate that the water bottle is placed on the side so it's easy to grab my water in a non-awkward way. Overall, if you're looking for a sturdy well constructed bike, you should definitely check this one out!

Top notch bike

Replaced my old bike with this beauty and I'm so glad I did! The construction and engineering is top notch. It's incredibly smooth and makes our workout feel more fun. Can't wait to get ride of those stubborn 10 lbs with this bike!

Everything I was looking for

It's surprisingly quiet! The resistance is smooth, bike doesn't feel jerky and it has all the features I was looking for in a bike like place for my water, phone, and I can use my clip-ons since the pedals are SPD compataible. All in all this is an amazing bike and everything I was looking for.

Happy to be spinning again!

Great bike! It's easy to use and easy to move around the house with the wheels located in the front. I'm 5'3" and can reach the pedals comfortably after adjusting the bike. Now I can stream my classes and start spinning again!

Impressive build

The construction is impressive and not at all flimsy. I am 5'7 210lbs and have no problem riding this bike. It's sturdy and doesn't rock even with my full weight on it. Flywheel provides a smooth spinning quiet ride. Highly recommend this bike.

Solid bike

It's a solid bike. Once on the bike feels sturdy. The seat was a bit uncomfortable in the beginning but I got used to it after a while.
