Biking can be an expensive sport.  At Hummel Park, in partnership with the Town of Plainfield, you can rent an adult bike located on the East side of Hummel park in the parking lot by the Playground.  Using an app called Koloni, bikes can be easily rented and returned to the same location or another location located in Plainfield.  The first 30 minutes are free of charge, so download the app today and take a spin!
