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 an electric motor device (ME) and a base support assembly (AB) having a base support shaft (SB). The present disclosure also relates to a bicycle frame or a frame interface unit (IU) and to an energy accumulator device (Si) for an electric bicycle drive unit (DU). The drive unit (DU) comprises an integrated energy storage device (Si) for powering the motor device (ME). The integrated energy storage device (Si) can be arranged adjacent to the motor device (ME) in such a way that the centre-of-gravity position (CGE) of the energy storage device (Si) and the centre-of-gravity position (CGC) of the drive unit (DU) lie in the floor support region (R).
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)中的电动自行车驱动单元(DU)。驱动单元(DU)具有电动马达装置(ME)以及具有底部支架轴(SB)的底部支架组件(AB)。本公开还涉及自行车车架或车架接口单元(IU)以及用于电动自行车驱动单元(DU)的蓄能器装置(Si)。驱动单元(DU)包括用于给马达装置(ME)供能的集成式蓄能器装置(Si)。集成式蓄能器装置(Si)能够与马达装置(ME)相邻地这样布置,使得蓄能器装置(Si)的重心位置(CGE)和驱动单元(DU)的重心位置(CGC)位于底部支架区域(R)内。
