The OU have made one of the units from their 'Sport: the science behind the medals' course available free online. The interactive unit (plenty of videos to watch), which is called 'The science behind wheeled sports' and which they estimate will take about 8 hours to complete, is available here:

They've also made available a series of films about the hour record, cycling aerodynamics, physiology, and forces. The films, which they've called 'The Science Behind the Bike' can be found here:
