    This kit seems to get good reviews...

    chain drive system with brushless assist motor...many people claim to like them better then hub motors :

    I have the same Panasonic drive on my Giant.
    I run it through a NuVinci. I think it is fantastic.
    I also have a Heinzmann hub motor on a Biria. The Panasonic drive is 350 watts. The Heinzmann is 400. Being able to take advantage of the NuVinci's gearing the amount of torque I can get from the less powerful Panasonic motor is vastly more than what I can get from the direct drive Heinzmann hub.
    The Panasonic setup acclerates faster, can move more weight, and climbs better than the Heinzmann.

    I got it from the local bike shop.
    It was around $1200 several years ago.
    The Giant was sold as the Twist/Lite but now Giant no longer uses the Panasonic drives and the current Twist has a front hub motor.

    I also love the torque sensor throttle on the Panasonic systems.

    The Panasonic drive is not able to retrofit to just any bicycle. It has to have a frame specifically designed for the mounting it requires. But the idea of a bb drive system is a good one and no one at this time makes one that will fit on a regular style bike. You can get a few kits that utilize a freewheeling crankset however that allow for use of the bikes gearing like this one here: http://www.ecospeed.com/

    the design seems to be better suited to create a good crank generator to power up more powerful stuff.
    similar to that experimental motor bike that is pedal powered

    very good for torque, high on maintenence, imagine it on even 1km road not paived.
    Maybe ideal on impeccable clean Japanese roads.
