When I was younger they were common. I liked them. They seemed to make a 14 mile commute through the city a more relaxed ride. They didn't have the fast city bikes back then(like the cannondale bad boy). They had big cruisers and road bikes, neither of these made sense for city commutes. The extra brake levers helped bridge the gap. I would like an updated 21st century design and positioning of these. Remember these were old style brake calipers with old brake pads on steel rims, of course they didn't work well. Nothing back then worked as well as they stuff out now.
