Abstract: A drive system for a pedal-operable vehicle, including a drive motor, pedals on pedal arms, a bottom bracket spindle on which the pedal arms are mounted, and a drive mechanism for transferring drive energy. A clearance is present in a transfer path between a pedal arm and a drive wheel, rotating with the bottom bracket spindle, of the drive mechanism.

Abstract: A method for ascertaining the total mass of an electrically drivable vehicle includes: ascertaining, for a purely electrically driven vehicle, a total mass of the vehicle on the basis of Newton's second law, taking into account a slope and a travel speed of the vehicle. As an alternative or in addition, a compression travel within a subassembly of the occupied vehicle is measured, and the total mass of the vehicle is inferred from a predefined or previously ascertained stiffness of the compression travel, taking into account a current weight distribution.
