(Tulsa, Ok)--The little chiming sound alerts you there is something other then cars and trucks on downtown Tulsa streets. Move aside as another pedicab rider makes their way from the Blue Dome District to the Tulsa BOK Center. Bethany Henretty and her husband run the three bike taxis and look forward to adding to the fleet as downtown flourishes. They pedal for a tip from $5 to $10 and hope you have fun on the ride. Henretty says services like her pedicabs add charm and character to downtown Tulsa. She also feels they could eventually be another of the attractions to bring more people to Tulsa's hub.
