Humans united can accomplish amazing feats, such as discovering fire, putting a man on the moon, and building a full-scale model of Nebraska in the Arctic Circle. Band together for a common cause with today’s Groupon for a two-hour pub crawl from Pedal Hopper in Denver. Choose between two options:

• For $15, you get an individual two-hour ride pass (a $30 value).
• For $180, you get a group two-hour ride pass for up to 16 people (up to a $360 value).

Pedal Hopper sends pub-crawling tipplers on a self-sustained journey around town on a covered, pedal-powered party bike. Exercise limbs while traveling to fermentation destinations at an average of 5–8 miles per hour, with a sober, tour-provided driver navigating the vehicle through roving herds of feral Clydesdales. Riders meet near the intersection of South Broadway and Archer before kicking off two-hour tours with swings through their choice of area pubs, buying rounds at alehouses including El Diablo, Candlelight Tavern, and Hornet. Each Pedal Hopper seats up to 15 revelers and one centrally located standing passenger positioned for passing out midtrip snacks or lobbing obstacles at opponents during midtour drag races.
