Depends on what your goal is, but one hour/day is OK if you want to increase endurance. Remember that it's not only about how long, it's about the intensity as well. Merely sitting there pootling along won't do you much good, you want to keep a decently elevated heart rate while you're at it.
If you are training for a bike race, an indoor bike trainer could help you with stamina and keep you focused on developing your body to handle each race better.
Each exercise bike offers an advantage, but it's important you find one which is right for you. If you enjoy using your exercise bike then it is a good one. You should always aim to purchase exercise equipment which is branded, as it is likely to be of a higher quality. Pick one which has features suitable for you - uphill biking, rolling hills, 5k and 10k settings are available on many models.
someone should exercise at the least of 30minutes a day. Also it should be a constant work out

Depends on what you mean.Can you get decent exercise on an exercise bike - Sure.But you have to be willing to put the effort in.If you're only on it for a few minutes at a time, casually turning the cranks - nothing will happen.But if you ride yourself sweaty and winded - for one hour, or thereabouts - several times each week - then it can really help you.But it also depends on what else you're doing.If you want to lose weight, the first thing you have to do is to control what you're eating. If you're overeating badly, no amount of exercise can compensate for that.
Good to exercise daily but if you do resistence training give each muscle group 48 hours before using it again.
Between 1-2 hours each day. About 3 days per week is what kids should get.
