If I was going to go for two wheeled power, I'd just buy a motorcycle. For $2,600 I could pick up a decent bike that would be much more functional IMHO.

My issue with E-bikes and, even more so, whizzer-style, gas-powered bicycles is that people tend to ride them the same way a lot of people ride bikes. On sidewalks, against traffic and oblivious to other's right-of-way. Doing these things at 20 MPH or more raises the danger-factor exponentially.
