摘要

The bicycle can travel on land in the usual way and on water using float bodies (3). The float bodies are preferably arranged on the wheels and have variable volumes. The rear wheel acts as a bucket or paddle wheel to move the bicycle on the water. The front wheel is used to control the bicycle movement on the water, preferably because of the shape of the float body on the front wheel.
