I'm at Interbike - They allowed me to attend as Media due to owning VisForVoltage. I've been collecting a bunch of information and have seen some very interesting bikes. I'll be posting some about this over the next few days.
Main thing to note is this is a big big big international trade show all about bicycles. The electric bicycles are a drop in the bucket here. I'd guess the electric bicycle presence is a little bigger than before, but I have no comparison as it's my first time here.
The Light Electric Vehicle Association appears to be a new feature of the electric bicycle scene. They had a set of meetings here yesterday which drew together a bunch of bicycle dealers some of whom currently sell electric bikes. Hopefully it'll turn out to be a good thing.
