Dave, Dave, Dave...
Ah-ha! You might be catching on, how about "you don't need any gears on an e-bike" for certain riding conditions. Such as riding around a flattish city in a suit and tie...
True,if you want to find a market for about 10 customers but most people want to go up hills at some time,for most that is the primary reason to buy an e-bike.
Do you honestly believe there is a market for an e-bike to suit the city slicker to ride only on the flat to work,surely electric bikes are just not cool such a guy/gal would be riding a Bianchi or Specialised,maybe with a fixer.
The higher power of an e-bike,that is rider plus motor power allows a bigger range with wider steps but you still need gears to get up hills,the low speed-high torque of a BPM motor helps but the additional weight is not appropriate on this style of bike.
I do think there is a limited market for a sports bike with power but G-tech didn't do their homework and are now paying the penalty for it.
It can be specd/designed to give a more broader market appeal but the right bits are only just starting to come out of the volume Asian manufacturers,it's probably 2 years away.
I know you want to hang a kit onto a nice bike but you still have to compromise with a highly visible downtube mounted battery and most home conversions inevitably have a spaghetti of wiring, that for me kills the whole concept of such a bike looking stealthy,sleek and simple....look at the Freygeist or Coboc,crazily expensive but that is how such a bike should look to the eye.

ps....completely off the subject I notice you live in St Jean de Luz...I once successfully competed in the First Class 8 yachting championships in Hendaye,towed a boat right across France to compete,that must be near to you.
