how could it be any worse than multiple reductions that you have to use with planetary and chain ? only one reduction with worm also the igh and shaft is less loss than chain and cassete

chain drive 95 to 98 % efficiency primary,secondary and bb to wheel 15 to 6% loss.............worm reduction 3 to 4% ,shaft drive 2 bevels 2% each,planetary in hub 3% total11%
