I bought a high quality and expensive white freewheel, but it is larger and requires machining to fit on my 120 pound bike, so have been consuming Dicta's until that project to fit the white completes. The Dicta's do last longer when lubricated. Plus they are much quieter.
The variable electric braking / regen makes brakes necessary only for emergencies and the last mph of braking to a stop on this ebike.
A geared and clutchless motor will make an interesting addition to the options. Normally it would have rather significant coasting losses, but with modern laminations perhaps it will be similar to a DD, though geartrain losses are never zero.
