HONDA Civic conversion - Reverse Motor Direction?

[madderscience]

most EV-sized series wound DC motors can be tuned to work efficiently in either direction.  There are probably a few out there that cannot, so best bet is to not worry about it until you have identified a particular make and model of motor, then ask about it on these forums or the EVDL, etc.  BEFORE putting down money.

Geos are common conversions because they are small and very lightweight, and good aerodynamically.  The smaller, lighter, and more aero, the better.  Assuming you are talking about a modern Honda Civic, those are more aptly described as a midsize sedan rather than a small car these days, though an older one might be a good candidate.   Two honda models that I did research when I was looking for my conversion chassis (I settled on a 1985 toyota MR2) would be the 1989-1991 honda CRX and the 1992-1995 civic hatchback, and either of these, particularly the CRX, would be an excellent choice from a weight and aerodynamics perspective.  I did not investigate battery carrying capacity.
