The 49lb flywheel matched with a really affordable price brought me to the Sunny Bike. This bike is very smooth to ride and easy to use. I have ridden it mercilessly for over 2 years and not had any problems. The bike shows almost no signs of wear and has taken very little maintenance.
Set up was super easy, but the parts are heavy and you may need help if the bike has to go up some stairs.
All the gear you need to set up and join Peloton's classes is cataloged in this post.
I love this bike and the classes from Peloton. Using this set-up over the last two years I've hit my target weight and am in better shape than almost any other point in my life.
