This spin bike is very sturdy. Solid. It is a no thrills spin bike without a computer for Heart Rate, miles, etc. I use my own monitors for HR so that was not a need of mine. The frame is really solid, the wheel is heavy and smooth, and it is a chain drive unit (which means it makes a little noise compared to a belt drive). I cannot speak for durability as I have used it about 10 times in a month, but I use it hard and follow difficult class formats and it feels similar to bikes at the gym. A solidly built no frills bike.
The is an excellent price for this bike. It is a great way to get in that workout without leaving the comfort of your home. The quality of the equipment is an indication of the safety of using the bike. I would recommend this bike.
