I can't think of the name of the show. It had two motorcyles one ridden by a girl the other a guy. The girl had a good bike the boys motorcycle was broken down with patches on the wheels but whenever someone was in danger he could change into a perfect bike and save the day. What was the name of the show?

Sounds like,.

Wonder Wheels

Wonder Wheels was much like a two wheeled Speed Buggy. Wonder Wheels, his mechanic/friend, Willie Wheeler, and a young woman named Dooley would travel the country on two seemingly ordinary motorcycles. Each episode they'd stumble into various mysteries, and bits of trouble. When they did, Wille's humble rundown motorbike could become the living superbike, Wonder Wheels.
It was originally run within the live action Saturday morining variety show The Skatebirds.
