<p>The invention relates to a bicycle frame preferably for electric bicycles, with a plurality of interconnected frame struts (1, 2, 3) including a down-tube (3), a seat tube (2) and a steering tube (4) and with a device for fastening of an energy supply unit to the down-tube (3), which fastening device has a pivot bearing (12) for the energy supply unit as a first abutment and a second abutment. In order to a provide an energy supply unit with good handleability and ease of installation, permitting a secure fastening, the frame strut forming the down-tube (3) of the bicycle frame is partially provided, on a flank facing the seat tube (2), with a cross-sectional deformation for forming a receiving depression (7) for the energy supply unit, the top flank (8) of which receiving depression forms a flattened, preferably planar, bearing surface for the energy supply unit, to which bearing surface a hook element (13) is fastened as a second abutment for the energy supply unit, wherein the pivot bearing (12) projects over the flank (3A) of the undeformed region of the down-tube. The invention also relates to the supply unit.</p> |
