Take one of your road bikes, depending on your set up, try a ride around town, never stop pedaling, try 42x18 gear to play with, then try say 42x16 etc etc this will give you an idea of what you can away from junctions without too much wobble or knee pain. Play around with your gears to find a nice ratio to start with fixed.
As you get used to fixed you can gear up.
I haven't mastered fixed skidding so use a rear brake, my 42x16 lets me cruise along at 16mph, i can fast cruise at 20mph and short sprint up to 25mph, it's also fairly easy to pull away from junctions and tackle hills around me.
Road only.
If you drill those forks part of the forum will have a meltdown :)
Something like this for front brake, you can do rear as well.........
