Michael Schumacher has ruled out a return to two-wheeled competition when he retires from F1 for a second time at the end of the season.

The seven-time champion previously tried his hand at Superbike racing when he retired at the end of the 2006 season, although a fall while racing played a part in him being unable to return to Ferrari in 2009 when he was approached to replace the injured Felipe Massa.

Schumacher's decision to retire for a second time at the end of the current season has led to talk about what the next step in his career could be, but he said he wasn't planning on heading back to bikes.

"I like to learn things and that's also the reason I won't go motorcycle racing again - because I've already done that," he told Frankfurter Allgemeine Zeitung.

"I enjoyed it a lot the last time I did it, but I learned something too and I came to the realisation that it's crazy to start another career so late in life. I don't want that anymore. I don't know what I'm going to do next, but that's the freedom I have now. The plan is to have no plans."

Schumacher is being replaced by Lewis Hamilton for F1 2013.
