Just added Columbia Cycle Works to the vendor directory (http://visforvoltage.org/vendor/vendor-type/8776) because they sell an interesting and affordable velomobile.
So, it's a tadpole recumbent with an aerodynamic shell. Sometimes I think I want one - e.g. in february when it was raining a lot. I suppose in Portland they worry more about rain than we do down here in the SF Bay Area ;-) ...
It has a 500W motor on-board but the site doesn't discuss the kind of motor or whatnot. It ships without batteries because there are regulations against shipping lithium batteries on airplanes.
The price is very affordable (unlike the other velomobiles I've looked at).
