The present disclosure relates to an electric bicycle drive unit (DU) for arrangement in a bottom bracket region (R) of a bicycle frame. The drive unit (DU) has a base support assembly (AB) having a base support shaft (SB), an electric motor device (ME), and an energy storage device (SE) for supplying energy to the motor device. The energy storage device (SE) can be arranged in a lower tube TL of the bicycle frame (1) having a closed tube cross section and can be removed from the lower tube TL coaxially to the longitudinal axis of the lower tube TL. The present disclosure also relates to a bicycle frame (1) or a frame interface unit (IU) and to an energy storage device (SE) for an electric bicycle drive unit (DU). When the drive unit (DU) has been mounted on the bicycle frame (1) and is in a standby state, the energy storage device (SE) is fastened directly on a housing (HM) of the motor device (ME) or in a common housing (HC) of the motor device (ME) and the energy storage device (SE).

    本公开涉及一种用于布置在自行车车架的底部支架区域(R)的电动自行车驱动单元(DU)。所述驱动单元(DU)具有包含底部支架轴(SB)的底部支架组件(AB)以及电动马达装置(ME)和用于为所述马达装置提供能量的储能装置(SE)。所述储能装置(SE)可以布置在所述自行车车架(1)的具有闭合式管截面的下管TL中,并且可以与所述下管TL的纵轴同轴地从所述下管TL中取出。本公开还涉及一种自行车车架(1)或车架接口单元(IU)以及一种用于电动自行车驱动单元(DU)的储能装置(SE)。当所述驱动单元(DU)已安装到所述自行车车架(1)上并处于待用状态时,所述储能装置(SE)直接紧固在所述马达装置(ME)的壳体(HM)上,或紧固在所述马达装置(ME)和所述储能装置(SE)的共用壳体(HC)中。
