But you pay income tax when you convert to a Roth? 
 As in the 50k you convert from pretax 401k to Roth, you pay income tax on that 50k.... so not tax free...

you pay income tax on the income bracket you are that year so for example I paid income tax for the 401k money that I transfered as a student. Since that was my only real income I had to pay no income tax on it
