Reva are the Indian company who came up with the G-Wiz. In the UK, a company called GoinGreen has made an excellent job of introducing the G-Wiz to the London market. Re-charging points have been cropping up around the city and the G-Wiz has become the poster child for electric cars in Britain. We just wonder whether Reva, GoinGreen, and the G-Wiz will be able to compete with the likes of Think, NICE, and ultimately Tesla as the electric car market gathers pace over the next few years.
