In that case, you're going to need an oversized motor to be able to handle either the torque demands of low-speed driving or the over-revving of high-speed driving. Similar types of engine stress apply to electric motors as to gasoline ones; the physics starts out differently but winds up in much the same place. Imagine always starting your Bug with the gasoline engine in third gear, or keeping it in second gear on the freeway...one way or the other, you're going to need an heavy-duty high-powered motor or else it'll burn up or blow up. If you go with something with enough oomph to be able to do away with the transmission, you'll get something not unlike a drag racer, which would certainly be a lot of fun. On the other hand, you'll likely save money by either keeping the original transmission (which is what the EVWest kits I mentioned in that other post do) or using some other variable gearbox.
