Drive-brake arrangement for a wheel, and electric bicycle

A drive-brake arrangement for a wheel of a muscle-powered vehicle (2), comprising:

• an electric motor (24) motor, with a stator (26) that is connected directly or indirectly to a frame part (32) of a frame arrangement (4), the stator (26) enclosing, in an at least partially annular manner, a disk-shaped rotor (28) having a speed nR, the disk-shaped rotor (28) comprising permanent magnets (30) and being connected operatively to a drive shaft (46) having a speed nA for conjoint rotation therewith, a brake caliper (34) being arranged on the frame part (34) and having brake shoes (36), the brake caliper (32) enclosing, in an at least partially annular manner, a brake disk (36) that is connected operatively to the drive shaft (46) for conjoint rotation therewith, and wherein the rotor (28) is connected operatively to the drive shaft (46) via a planetary transmission (48) in a transmission housing part (50) in such a way that a transmission ratio i=nR/nA>1 is present.
