Great Service by Angelica!

This company provides the best customer service I've ever experienced. Angelica is great!


This bike is great!

This bike is great! It helped me solve a number of problems and inconveniences. It's very inexpensive for the level of quality you get. It's easy to assemble. It does what Sunny says it'll do. It's perfect for a novice cyclist who doesnt want to work out at the gym. Aside from a few little issues I've a fantastic experience with this spin bike! 4.5 stars out of 5. I wrote a full review over at cyclingtek.com if you want to read about my entire experience.


This sturdy bike a great value.

I'm a casual 25-mile road cyclist and use this quiet bike for an hour while watching TV or turn up the tension to get the most out of a cycling video. This sturdy bike a great value.

Meat and Potatoes Spin Bike

You really don't need anything more than this for a Spin Bike. Don't be fooled into buying a Peloton bike for 4x the price! You can buy THIS BIKE and just use a phone or tablet to stream live workout videos, and prop it up in front of you! The Sunny has the 40-lb flywheel, overall sturdy feel and build and the craftsmanship is very, very good. For the price you're getting everything you need for a classic spin workout, without all the fancy bells-and-whistles and unnecessary features found in more expensive bikes. Simply get this bike, and buy your own SPD foot pedals pedals (under $50) and Cadence Meter (also under $50)....now you have your own Peleton for much less! What else can i say? I a super solid bike at a rock bottom price. Its a steal.
