This bike is very sturdy, it's easy to adjust the saddle height & position. I'm 5ft and I was concerned it may be too big for me but it's fine and I'm not even on the lowest setting for the seat. The IFIT programme is great offering a wide range of programmes but you really need the IFIT with the bike as there is not really any manual options (that we have discovered). My husband put the bike together without any problems and the bike is really well made and really heavy, so build it in the place you want to use it. The spin section is quite but there is some noise from the movements when the bike goes up & down inclines. We love this bike, it is great for keeping fit.
