There are a few companies doing EV conversion kits, mostly for the original VW bus, the VW Beetle, and the venerable (and much missed) original VW Golf, of which there are probably around 4 million in my country alone, seeing as they were locally made for 38 years with minimal upgrades to the basic design, aside from those due to needing to replace whole swathes of the production line, as it fell apart from wear. There are some EU based converters, who do EU spec vehicles, and they seem to be doing well in a bespoke way. Depending on the company, it varies in range and power, and in battery type. Some are highway legal, as they can reach 80kph, while others will only reach 60kph.
