Motordoping in film The Program In the film The Program, about the career of Lance Armstrong, there is a scene (at about 29:45 minutes) where his mechanic turns around something on his bike and afterwards he climbs up the hills like no one else.  

So I have 2 question:  


Did Lance Armstrong cheat to win his first Tour de France using some kind of motor?
Was it even possible in 1999 to hide such an effective motor in a bike frame?
I'm torn here between attempting to answer this question, and voting to close it on the grounds that you'll only ever get an opinion-based answer. But, to give the benefit of the doubt....

For the first part of your question, I'd say it was unlikely, but your pertinent words are "using a motor". He may well have cheated using other means, in  particular the blood doping for which he is now infamous. 

This is largely because I think the answer to the second part of your qurstion is "no". I think that in 1999, battery technology was sufficiently primitive that it would have been impossible to conceal a motor, or that a motor that was concealable would deliver such negligible power as to be ineffective when it comes to increasing your speed. I mean, this is arguable even with 2016 technology - have a look at the size of a bettery on one of today's e-bikes, and you'll see why I say this.

I think you only have to look at mobile (cell) phones of the day to convince yourself of the limits of the technology. My gut feel is that any film you watched which showed motors was using lots of artistic license - if it contained a pile of syringes, I'd be a lot more convinced.
