The current generator is located at a wheel (1) and held by a support frame (2) of a training unit. The current generator has a permanent magnet (4), which is fastened to the wheel and an induction pick-up coil (3) which is fastened to the support frame and is arranged for the permanent magnet. An induction voltage is produced by the induction pick-up coil of the permanent magnet with each turning of the wheel and which is approximated.
