I have LR's BB kit on a 14 Glory and it's amazing. I'm having some issues with the cogs slipping on my freehub body. I'd like to switch to a freewheel but I'll need to make a custom hub and make sure the chainline is perfect... we'll see how that goes, i'm going to need some help.
my advice: get a mid drive kit, LRs is great (you dont need the BB). Buy a beefy chain and use the 3-way switch on a CA to tone down the power.
