A drive assemblage is described for a vehicle drivable by muscle energy and/or&#x2014;in particular additionally&#x2014;by motor energy, to an electric bicycle, e-bike, or pedelec, having: a crank spindle rotatable around a rotation axis for receiving a first torque that is generated in particular by muscle energy; and a transfer device that is embodied to transfer the first torque from the crank spindle to an output drive element couplable to a drive wheel of the vehicle, and is embodied, by way of an&#x2014;in particular automatically&#x2014;shiftable spur gear transmission, for a variable conversion ratio, in which: the spur gear transmission has a first shiftable spur gear transmission and a second shiftable spur gear transmission separate therefrom; the first shiftable spur gear transmission and the second shiftable spur gear transmission have a common transmission output to the couplable output drive element; and the first shiftable spur gear transmission and the second shiftable spur gear transmission are couplable alternatingly and alternatively into the power and torque flow of the transfer device.

Drive assembly and vehicle

A vehicle which is operable by a motor and/or muscular energy, in particular an electric bicycle, which includes an electric motor, a crankshaft drive having a first crank, a second crank, and a crankshaft, a torque sensor for detecting a torque applied by a rider at the crankshaft drive, and a control unit, which is set up to actuate the electric motor based on at least the values acquired by the torque sensor to drive the vehicle, the torque sensor being situated at the crankshaft drive and the torque sensor including at least one surface acoustic wave sensor.

Vehicle which is operable by a motor and by muscular energy and has an improved torque sensor
