Billed as the world’s largest indoor bike park the Louisville Mega Underground Bike Park is sure looking like it’s ready to ride for their opening. The park opened this week offering 320,000 square feet of riding space. There are over 45 trails featuring jump lines, pump tracks, dual slalom, BMX, cross country, and single track. The park is 100 feet underground and keeps a constant 60 degree temperature year round. They don’t have bike rental available yet but that should be ready in April.
