Dang, so nobody out there sells a battery that can be put in a hub? You have to buy the whole bike?

I think batteries are what's really holding back the e-bike technology/development. You can buy a conversion kit anywhere that inculdes everything you need to convert a regular bike to an e-bike. You can also buy all the components seperately- but just try to find the batteries.

If batteries were as readily available as the motors and controllers, there would probably be top notch e-bikes for sale all over the place.

That's really too bad that the hub mounted batteries aren't readily available. That would have been the percfect solution to my needs.
