peteThe third of our talks by local cycling luminaries is now available for your perusal!

The University of Bristol’s Pete Shadbolt (above) is a particle physicist, climber, musician and general polymath. Using a combination of hand-drawn slides, a knackered old mountain bike, and a whole lot of scientific nous, his talk at 2012’s Festival explains why bikes are so efficient, why a wobbly two-wheeled vehicle is so stable when it’s moving, and why puncture-proof tyres are a rubbish idea.
