Went and took a look---WOW! Nice to see these bikes being ridden instead of in museums, although the owners are definitely risking the bikes and themselves. Never mind electric start, most of these still start with pedals. Truly impressive. I'm going to assume your friend is not the local d.j.? If he competes again next year I think we should send him a club t-shirt to wear on the ride- or maybe a sweatshirt to keep him warm. Pretty sure none of these bikes have an electrical system capable of supporting an electric vest. CHEERS.
