There is a guy who makes his motors and frames in the USA with parts made in USA. His battery packs are Panasonic cells made in the USA as well. 95% of his components are sourced from the USA. He also provides kits with his 48V + geared motor rated at 700W and peaks at 1400W mounted on a nice rim with thick stainless spokes. It has cruise control. You can choose any rear gearing up to 10 cogs. Three year warranty on everything!
That means you can choose any bike you want and turn it into an electric bike. How cool is that?
I ordered one for a 24 speed GT Mtn Bike and will review it somewhere once it is put together.
