Exercise bike upstairs?

[DirtyFlirtyGerty]

Hi, ive just brought an exercise bike/cross trainer (35kg) and I was just wondering if it was safe to use upstairs? I weigh 10 stone if that means anything

Why, have you heard of anyone crashing through their upstairs floor while exercising?

Because I haven't. Pretty sure you'll be ok.
