Tilly and Jack take over the show and go bike crazy. Heading to one of the coolest BMX parks in the country they meet up with champion BMX rider Matti Hemmings, and learn some amazing tricks. Back at home they get to ride a precariously high penny-farthing before Tilly gets baking. Inspired by their bike-tastic day she makes a delicious summer soup and a loaf of bread tattooed with a Tour de Tilly logo. Then using a clever invention and pedal power to do the hard work she and Jack churn their own butter to spread on the freshly baked bread.
