French designer Philippe Starck has unveiled four electric bicycles and a collection of matching cycling accessories at the Eurobike event in Germany today, including a bike with a furry coat (+ slideshow).

Philippe Starck's Starckbike company and manufacturer Moustache Bikes created the MASS range of electrically assisted bikes based around a standard model, designed and assembled in France.

The bikes all have batteries that provide additional power on top of the pedalling action of the rider.

"This is more than a bike, it's a machine to generate pleasure through hybrid technology that combines muscular effort with the assistance of an electric motor," said Emmanuel Antonot of Moustache Bikes.

"The synergy between man and machine occurs naturally and seamlessly allowing users to enjoy the comfort of a motorised two-wheeler and the agility of a bike."

MASS stands for Mud, Asphalt, Sand and Snow – the names of the four bikes that have each been adapted for specific terrains.

"I wanted the bike to be able to go over all kinds of terrains and especially infinite and poetic territories," said Starck.

The Mud model with grayscale colours features a dual-suspension frame, optimised gears and Shimano XTR brakes suited to off-road riding.

Designed for urban cycling, Asphalt is available in 25- and 45-kilometre-per-hour versions for zipping around the city.

Sand includes extra large tyres for better grip on coastal tracks and a rain cover that contains storage pockets.

Large tyres also offer lift and traction for the light-coloured Snow design, which has a mono-arm fork for optimum snow evacuation and a fur frame cover that protects the battery from extreme temperatures.

Each bike comes with a set of accessories in materials and colours that complement its features.

The bikes each have two corresponding helmet styles that include visors shaped for different weather conditions and aerodynamics.

Colour-coordinated sunglasses, tan and black leather backpacks and matching gloves complete the range.

The designs were unveiled at the Eurobike event, which opened today and continues until 30 August in Friedrichshafen, Germany.

Starck's Pibal electric bike-scooter hybrids were rolled out across Bordeaux earlier this year as part of a free cycling scheme.

The designer previously created a motorbike for French motorcycle manufacturer Voxan.
