Abstract: A drive apparatus for providing assistance in the propulsion of an HPV, the HPV having, a bottom-bracket assembly comprising, a bottom-bracket axle, and a pair of cranks, a bottom-bracket output for onward delivery of propulsive drive which is attached to the bottom-bracket axle. The drive apparatus comprises: a drive-wheel being configured to deliver torque into the bottom-bracket axle through a connection which is axially positioned outboard of a bearing supporting the bottom-bracket axle; a motor comprising a rotor; a motor-output wheel which can, when the drive apparatus is connected to the bottom-bracket assembly, revolve about an axis parallel to and offset from bottom-bracket axle; a drive-element which can couple the motor-output wheel to the drive-wheel so as to deliver torque from the motor to the drive-wheel; a one-way clutch in the drivetrain between the rotor and the bottom-bracket assembly, configured to engage when the rotor is revolving at an engagement speed, and to disengage when the rotor is revolving at a speed less than the engagement speed; and a controller configured to receive data from one or more sensors and to estimate from the data a force applied to the bottom-bracket axle by a rider through the cranks, and configured to use this information to decide a level of torque that the motor is to apply to the rotor.
