  • TW201726210A discloses a bicycle resistance training device suitable for being mounted on a bicycle.
  • this device is not suitable for users who want to train being in a hilly terrain with both slopes and descents, while physically being in a flat terrain.
  • a first aspect relates to a cycling training device comprising:
  • variable resistance unit adapted for reliable engagement with the tread of the tire of a bicycle wheel, thereby variably affecting the rolling resistance of said bicycle wheel; wherein the variable resisting unit comprises a disc eddy current brake system; and
  • variable resistance unit adapted for positioning the variable resistance unit into reliable engagement with the tread of the tire of a bicycle wheel at a position above the hub of said bicycle wheel.
  • the term“rollable engagement” is to be understood broadly.
  • the principle is that the tire of the bicycle wheel is forced to rotate a part of the variable resisting unit, such as a roller.
  • the user can e.g. experience a ride in the mountains even though he or she is riding in a flat terrain. It is important that a part of the variable resisting unit can roll together with the bicycle wheel to reduce the friction between the two. Otherwise, the tire of the bicycle wheel will wear prematurely.
  • the term“tread” is to be understood as the portion of the tire that contacts the road surface.
  • the present invention allows the user to ride his bicycle under natural conditions opposite the current home trainers on the market today. Furthermore, the positioning of the variable resisting unit is important to minimize the wear of the tire’s tread, which is a common problem with home trainers.
  • the variable resisting unit When the variable resisting unit is positioned into rollable engagement with the tread of the tire of a bicycle at a position above the hub of said tire, only the weight of a part of the cycling training device is contributing to friction between the bicycle wheel and the variable resisting unit, as compared to the weight of the rider and the bicycle in a home trainer setup.

  • the U-shaped or C-shaped magnet is configured for being movable radially back and forth relative to the centre of the rotating disc, thereby causing the said rotating disc to move a) deeper into said space, or b) further out of said space, or c) completely out of said space, thereby varying the effective rolling resistance.

  • the electronic control unit comprises a central logic processor, a display, and buttons. Even more preferably, the display and buttons are integrated into a touch screen.
  • the electronic control means further comprises a communication means adapted for communicating with the variable resistance unit and configured for instructing the variable resistance unit to vary the effective rolling resistance in accordance with user and preferably sensor input into the electronic control means.
  • User input may e.g. be a user's training programme, such as how much power the user needs to produce.
  • User input could also be the weight of the user, the diameter of the wheels, and the weight of the bicycle, which are all relevant inputs in order to determine or calculate the correct resistance at a given time during the ride.
  • the sensor input could be from a heartrate meter, a bicycle speedometer, a bicycle power meter, and/or a a bicycle inclinometer.
