The bicycle manufacturer Cannondale is well known for its high-performance bikes—pricey chariots that are ridden by some of the world's top pros in the elite trail- and road-cycling ranks. But things were not always so. The company's first cycling-related product, released way back in the early 1970s, was a bike trailer called the Bugger. You'd mount the accessory two-wheeler to your bicycle's rear triangle and use it to haul groceries, bags of potting soil, or your toddler.
