I have yet to hear anything negative about Electric Bike Company bikes, although I have no personal experience with them and haven't researched them thoroughly.
I went as far as calling Crazy Lenny's about purchasing a Gepida Fastida. It is a bike which 'speaks' to me, although it was not a 'need' purchase. A couple weeks back the Fastida's were on CL's 'overstock' page priced at $1,980. When I called they said that they wouldn't take any more off the price, but would ship for $50 instead of the normal $200. But I still couldn't pull the trigger.
A little while back I did purchase a Gepida Thoris tandem as an anniversary present for myself and my wife. Gepida is not well known in the U.S., but is highly respected in Europe. The build quality, engineering and spec level on the Thoris is all very good, and I assume it will be as good on the Fastida. Not many reviews about it on the webs either, but I'm certain it is a very capable bike. Much more refined and efficient product as compared to R1U, Rad or Aventon level bikes. And I do love speed pedelecs.
