  Bicycle drive with freewheel and coaster brake.



   The present invention relates to a bicycle drive with freewheel and coaster brake, in which the drive and the braking are effected by means of one and the same cone
 EMI1.1
 are provided, between which balls are stored, so that when stepping forwards and backwards the cone is pushed axially against the friction surface and causes the clutch in the first case and braking in the second.
 EMI1.2
 wall a recess is provided to reduce the friction on the axle. Between the bodies f and f, two steel balls r are embedded in their recesses z and Zl

   PATENT CLAIMS: 1. Bicycle drive with freewheel and coaster brake, characterized in that drive
 EMI2.2
 of the sprocket carrier (f) two sector-shaped, saddle-like recesses (z, z1) are provided between which balls (r) are stored so that when pedaling forwards and backwards the cone is pushed axially against the friction surface, which in the first case acts as a driving force. in the second case acts as a braking surface.
