I hope you didn't buy it before reading post
#7 in this thread. I bought a BikeE AT about 19 years ago when the company was still in business. It was easy to learn to ride and could be adjusted to fit nearly anyone in a few seconds. That's about all I could say good about it. It was pretty inefficient. Mine suffered a catastrophic failure of the internal hub a few years after I bought it. Eventually ended up in the trash flushing about $700 down the drain.
