Joining the existing Black, Silver and Purple options are the Bianca and Marine Ciclottes, aimed at the high end spa hotel and health club markets.

Developed by Milan-based designer Luca Schieppati, the original black Ciclotte is already popular with the rich and famous - the newly launched Bianca model is an infinitely cool white version.

The Marine is designed to be even tougher and is wholly weather-proof; ideal for yachts and outdoor living spaces.

Both are made with high quality materials including carbon, steel and glass fibres.

The Marine is also made with special steel, and has black zinc treatment for ferrous components as well as electronic components isolated by a surface of resin.

Ciclotte is the first exercise bike to use an epicycloid system.

This works by generating a concentrated magnetic field using a copper ring which is rotated at a high speed in front of five magnets, which can be moved back or forwards via the touch screen display to control the strength.

Other distinct elements of the bikes' design include the carbon handlebar, the touch screen display and supporting fins for stylish stability.

The Black and Marine versions are all carbon fibre; the versions in other colours have the seat, flywheel rim and hand-bars in carbon fibre and the frame plated in glass fibre.
