  • the present invention falls within the technical field of bicycle supplements that allows two people to travel on the same bicycle.

  • the present invention proposes a tandem equipment intended to be installed on a standard bicycle and which allows a passenger to be transported, that is, a second person, and who also pedals.
  • the great advantage of the tandem equipment described is that it allows the passenger to collaborate in the movement of the bicycle so that the driver does not have to make all the effort of the trip.
  • the tandem equipment comprises an additional saddle so that the passenger feels and is mounted on a frame formed by a piece of vertical structure, which joins the bicycle chassis and an additional vertical structure piece that is on which The pedals for the passenger are mounted.
  • the joining of the vertical structure piece to the bicycle chassis is done in the portions of the chassis intended for the placement of fenders or saddlebags.
  • the tandem team also includes a piece of horizontal structure configured to join the bicycle chassis in the frame of the bicycle or in the seatpost that starts from the frame and that supports the saddle of the bicycle.
  • the pedals for the passenger are mounted on axles that do not match that of the rear wheel. This, on the one hand, prevents interference between the movement that the passenger prints and the movement that the driver prints, and on the other hand, allows the passenger's pedals to be moved away from those of the driver. The distance between pedals prevents crashes during the pedaling of the driver and the passenger.
  • the movement of the passenger's pedals is transmitted to the rear wheel of the bicycle through a transmission chain (attached to a sprocket that moves the pedals) and through an attack wheel.
  • Said attack wheel is linked to a second axis of rotation that is driven by the movement of the pedals (transmitted by the chain) and is in contact with the rear wheel.
  • the movement between the two is transmitted by friction when the attack wheel turns on the rear wheel.

  • the tandem equipment additionally comprises a reduction mechanism with a first gear (9) that is linked to the second axis of rotation (12), and with a second gear (10) that meshes with the first gear (9). At the same time said second gear (10) rotates on a third axis of rotation (14) on which the attack wheel (7) is also mounted.

  • the tandem equipment comprises an anti-recoil system in the attack wheel (7), pulling on the wheel when it is turned in the forward direction and being free when it is turned in the opposite direction.
  • the movement is transmitted in a single direction of rotation, leaving the attack wheel (7) released in case of turning in the opposite direction. That is, the movement of the rear wheel of the bicycle is not going to force the rotation of the pedals (5) at any time, nor can they rotate the rear wheel of the bicycle in the opposite direction of the ride.
  • the anti-recoil system has been arranged on the attack wheel (7) to ensure that the maximum number of tandem equipment elements remain still if it is not pedaling. In this way, the drive chain (13), the sprockets (8) and the second axis of rotation (12) remain still if you do not pedal, even though the bicycle is moving forward.
