As soon as Karen Primm saw the video — about an Australian man who designed a tandem bicycle with a wheelchair in the front, so that his disabled wife could go out on rides with him — she knew she needed to bring something similar to Pittsburgh. Luckily for her, that exact piece of equipment — the Duet Bike — is manufactured right here in western Pennsylvania. “Mobility & Access Inc. makes the bikes in Oakdale,” Primm said. “When we went and saw the bike, it was everything I hoped for and more.”
