Dick Strawbridge and Jem Stansfield help a café in England's historic Bath deliver lunch to customers without adding to the city's smog and congestion. Air-powered mopeds might be the answer.
Traveling to Bath, England, Dick and Jem meet up with an eco-minded sandwich shop owner eager to create an environmentally-friendly delivery vehicle.
Riding around town on a tandem bike, Dick and Jem experience first-hand the challenges of creating a green vehicle able to cope with the hills and cobblestones of Bath. To build a lightweight 'green machine', Dick and Jem will need to make something small and agile -- able to accelerate uphill and manoeuvre through traffic. The solution: an air-propelled motorbike.
