Pedal It! celebrates the humble bicycle--from the very first boneshakers to the sleek racing bikes of today, from handlebars to…
spokes to gear sprockets--and shows you why and how bikes can make the world a better place. Not only can bikes be used to power computers and generators, they can also reduce pollution, promote wellness and get a package across a crowded city--fast! Informative but not didactic, Pedal It! encourages young readers to be part of the joy of cycling.
