The present invention relates to an auxiliary drive arrangement for a pedal-powered vehicle having a drivetrain comprising a pedal- driven sprocket and chain (15B) for connecting pedals (34) to a driven wheel. The auxiliary drive arrangement comprises: an electric motor (6) arranged to be mounted to the vehicle; a power source (14) for the electric motor; and a sprocket member (24) comprising first and second sprockets (24A, 24B). The sprocket member is configured to be selectively attachable via an attachment formation to the drive train of the vehicle. The sprocket member is configured to be mounted on an existing pedal sprocket and operatively connected to the electric motor to provide a drive path from the electric motor to the pedal-driven sprocket via the sprocket member.
