This tricycle moves on both water, land

Students from Southampton University's School of Engineering have designed a tricycle that moves seamlessly from land to water. According to the designers, the machine could be used to deliver aid to flood-hit areas.

The amphibious trike is the final project of seven students, who began working on the project in October - eight months before mechanical engineering student David Edwards finally took to the water to test the cycle. "When the cycle hit the water it was a very proud moment,".

"It certainly raised a smile from everyone who saw it. "All seven of us worked so hard on the project, and it was brilliant to see everything working perfectly.

"There are other amphibious bikes on the market, but the one we have designed is unique because it uses floats, a paddle wheel and the rider sits in a recumbent position. "Also, the transition from land to water is completely seamless which is very rare," he added.
