"Boulder Bcycle recently unveiled The B.E.A.S.T. (Boulder Bcycle Electric-Assist System Trailer) on the streets of Boulder. The Optibike e-bike and Surly trailer combo allows Robert Rowe, the operator, to greet tourists, students, and anyone else curious about the bikeshare program. The trailer can carry up to two of the famous red bikes, so the fleet can be balanced between stations easily. Robert also keeps cold water, and CLIF bars to keep Boulder riding. You will see The B.E.A.S.T. mostly on weekends, or in the early mornings and late afternoons in Boulder Bcycle's current coverage areas."
