I bought this bike to use while watching tv and using the iPad. The seat it hard. I mean really hard. But it depends on your body structure. My kids find the seat fine for their use. They will ride the bike for more than 30 minutes at a time. If I am riding for longer than 30 minutes then I will have to sit on pillows to feel better. The sit does adjust pretty easily. The bike is very sturdy and is quite heavy to me. So if you want to carry it upstairs you will needs at least two people. My teenage son assembled the bike with no problems. The tension is fine and it's just your standard bike almost old school. I never use the digital display. I used to use it until my rechargeable batteries got stuck inside and tore off the cover to the batteries. I bought this bike a while ago and I still ride it as does the family. I guess the seat is now broken in because I am now able to sit on the bike for more than an hour without any pain.
