A bicycle in which each of the two pedals (4) is mounted on a crank (5) with a lever arm which is variable during pedalling, the crank comprising a proximal portion (51) connected to the chainring and a distal portion (52) on which the pedal (4) is mounted, in which the distal portion (52) is pivoted (53) to the proximal portion, thus being able to extend away from the chainring, and an elastic return means (54) is provided which is located between said two crank portions and tends to counteract extension of the crank and draw the distal portion back towards the proximal portion.
