On a regular day in New Braunfels, groups of 16 people can be seen pedaling down the street, perhaps drinking beer as they go. They aren't a crowd of irresponsible cyclists: rather, they're passengers on the PubCrawler of New Braunfels. With seating for a driver, 10 pedaling riders, and 5 other passengers on a rear bench, the pedal-powered bus rumbles along at leisurely speeds of up 5 miles per hour.

Though it's been used for events ranging from bachelorette parties to parades, the PubCrawler—true to its name—most often wheels out for pub crawls. For these outings, the bike embarks along scenic areas such as the historic Town Square, pausing only for drinks at up to three pubs. All rides are BYOB, but passengers are required to bring only glass-free containers, such as cans or an entire fermentation tank. On-board taps with ball or pin-lock connections also allow riders to tap into their own pony kegs.
