摘要： A frame for a pedal driven vehicle, the frame having a first portion that defines an open channel. The frame includes fixture points for releasably securing a drive assembly having a crank axle to the frame, such that the drive assembly can be secured in the open channel, via the fixture points, so as to define an operational crank axis of the drive assembly. The frame defines one or more compartments for receiving a battery, so that the battery can be arranged in communication with the drive assembly for the transfer of motive power from the battery to the drive assembly (i.e. for driving the crank axle) whilst the battery is located in the compartment. The drive assembly is moveable in and out of the open channel in a movement which is in a non-axial direction of the channel.
