Pizza-powered Longtail Cargo Bike

Big Dummy is Surly's analog longtail cargo bike meant to make you rethink how you carry all your crap. Since 2008, Big Dummy has helped families cut their car dependency and business owners cut their carbon footprint; it’s helped friends move and hauled the pizza to the party. Saddle this beast up with a month’s worth of groceries, lumber from the hardware store, your tiny humanoids, or anything else under the 400 lb rider + cargo weight limit. Even if you don’t have a heavy load, there’s freedom in just chucking everything you need for the day into the Dummy Bags and knowing you can pick up any #GroundScore you find along the way — pretty smart if you ask us.
