Railbikes

Evidence that northern Colorado communities once were served by a robust network of rail lines is visible in many of the places that have not yet been covered with houses. In fast-growing Erie, Colorado Railbike Adventures has taken over a few miles of idled track near the historic Boulder Valley Mine to create a pedal-powered journey.

The route starts above Old Town Erie, and drops down into town, crossing Coal Creek on a 130-foot long timber trestle. Participants move as fast as four people can pedal the modern version of a cart designed for track maintenance crews. Tip: Try it around sunset.
