Water Bicycle
A hydrocycle is a bicycle-like watercraft. The concept was known in the 1870s as a water velocipede and the name was in use by the late 1890s. Power is collected from the rider via a Crankset, crank with Bicycle pedal, pedals, as on a bicycle, and delivered to the water or the air via a propeller. Seating may be Upright bicycle, upright or recumbent bicycle, recumbent, and multiple riders may be accommodated in Tandem bicycle, tandem or Sociable, side-by-side. Buoyancy is provided by two or more Float (nautical), pontoons or a single surfboard, and some have hydrofoils that can lift the flotation devices out of the water. Brands include Seacycle, Hydrobike, Water Bike, Seahorse (Cross Trek) and itBike. Kits exist to temporarily convert an existing bicycle into a hydrocycle.

Inorganic Compound
An inorganic compound is typically a chemical compound that lacks carbon–hydrogen bondsthat is, a compound that is not an organic compound. The study of inorganic compounds is a subfield of chemistry known as ''inorganic chemistry''. Inorganic compounds comprise most of the Earth's crust, although the compositions of the deep Mantle (geology), mantle remain active areas of investigation. All allotropes (structurally different pure forms of an element) and some simple carbon compounds are often considered inorganic. Examples include the allotropes of carbon (graphite, diamond, buckminsterfullerene, graphene, etc.), carbon monoxide , carbon dioxide , carbides, and salt (chemistry), salts of inorganic anions such as carbonates, cyanides, cyanates, thiocyanates, isothiocyanates, etc. Many of these are normal parts of mostly organic systems, including organisms; describing a chemical as inorganic does not necessarily mean that it cannot occur within life, living things.
