Someone correct me if I'm wrong, but I'm pretty sure that the Peugeot 106 Electrique EV sold in Europe during the 1990s and early 2000s used a single speed transaxle and a sepex DC motor. I don't recall ever reading that it had anything like the driveability quirks you describe for your SCT Rabbit. Maybe one of our members from the UK or the EU can comment on that. I also own an Elec-Trak tractor with a sepex motor (actually compound with a weak series field), and it suffers from none of the bizarre driving behavior you describe. Mine has a transistorized sepex controller, but originally the Elec-Trak had a simple high-current series "toaster" resistor network for the armature, and smaller resistors to control the field. With either controller, there's no weird startup sequence or idling. The motor runs and reverses like any other normal EV motor. Driveability is excellent. With the Alltrax controller, I can move the tractor by centimeters in either direction. I've driven golf cars with sepex motors, too. No quirks there either. I've never met any of the VW factory conversions in person, so I can't say how they would drive. However, I'd be surprised if VW would produce something as annoying to handle as your Rabbit sounds. FWIW, I recall seeing a couple of big Siemens motors and controllers at Recycled Bugs Inc (AKA The Parts Place) in Michigan in the 1980s. I didn't know how they'd gotten there at the time, and none of the counter guys knew anything, but I suppose it's possible that they'd come from vans similar to the one that Zwbus has. If so, it's pretty sad to say, but most likely RBI stripped and sold the body parts from them. There must have been something unique about the SCT Rabbit conversions that caused them to behave in such an uncomfortable and unfriendly way. I'm no expert, but from your description, it sounds like SCT wanted to avoid using any armature control at all. Presumably they did that to make the car cheaper. But good grief, how many people would test drive an EV like that at a dealer and then actually buy it? You'd have to be a pretty dedicated EV gearhead to accept that. No wonder SCT went bust.
