Bristol and South Gloucestershire councils are leading on the Cycling City project, working with Bath & North East Somerset and North Somerset councils to promote cycling across the region.
Between mid-July and mid-September Cycling City is running a bus advertising behaviour change campaign to encourage more people to get on their bikes.
Today (Wednesday 21 July) we spotted the first bus to carry the advertising. If you take a First Bus sometime soon you'll also notice one of five different 'testimonial' ads on the inside.
