Even in a 1 X 10 I sometimes skip gears up-shifting (mid drive, backing off pedal pressure to shift), then there is the Stealth Fighter, a 1 X 1 with a schlump drive, so a backwards 2 X 1. The rohloff is beautiful and robust, but I suspect 14 gears is too many on the up shift, unless you can skip gears with it. You have to STOP pedaling to shift with it IIRC. The review of the Optibikes on the 'other' e-bike review site really lowered their stock in my mind, a beautifully crafted child of love, but did that passion blind the team of that which the everday e-bike riders want and can DIY for a grand or two? Of course there are 3 & 8 speed IGH out there, but I've personally damaged the 8 speed affine under human power, so I'm not sure they are ready for 50 or 60 NM. For me the freewheel is as necessary as seatbelts, but simple drive lines and fixie, or track bike styling Q's are already showing up in custom and limited commercial builds (Farraday). Maybe a pair of small diameter hub motors, little 250's with some clever battery hiding would catch on,.. probably somebodies kickstarter WIP (work in progress) right now. Sorry if this was too abstract of off topic. -S
