This bike is a very comfortable ride that supports your lower back during a workout. We have very old and tired joints and the 400Ri has proven to be very gentle on them. The pedals are smooth and easy on the knees as well and don't cause your knees to lock during the ride. The seat is adjustable for multiple different heights. Above the display there is a ledge large enough to support a tablet/ipad but also can hold any cell phone for video or audio use. There is Bluetooth capabilities to connect your phone /tablet to the bike and an audio jack for listening. Overall the assembly was easy and able to be done in under an hour.
