Looking back, I did a lot of research up front about what bike to get, how heavy the fly wheel should be, and what type of resistance. They continue to go strong and I love them. It has been 9 months and over 150 rides of my Sunny SF-B1002 Bike and moofit cadence sensor. Last year I ventured into building my own workout area at the house, and it all started with a $400 investment to put together a DIY spin bike.
