>>1340570As someone who has a heavily customized folding bike with Alfine 11speed and dyno front hub - Don't Do It. The weight increase is huge compared to derailleur and a decent battery light. And on those occasions when you have to carry it folded - Jeesus.
Disc brakes on the other hand, were worth it. Smaller diameter wheels rotate at higher rpm, hence more heat on mountain descents, rim brakes higher risk of blowing tires.
