Great, another moped design so people get even less exercise. It's more elegant to have direct assist in the hub, I'll give them that. I just can't help thinking that for those who don't need the exercise (non-Americans) there are more rugged, cheaper, SAFER, and more efficient motorized bikes.

Could be wrong. :-)

Might be more elegant from a visual standpoint, but I believe there are major compromises required in a direct drive motor with suitable torque and rpm for a pedal assist bike? Recently Bosch got into the pedal-assist business and they have (according to a friend that worked with them) really done their engineering homework. Their system uses a smaller, higher rpm motor with reduction gearing.
