An electric bike 200 is described and includes an air speed sensor 218 to sense air speed at the bike, an electric motor 205 to impart motive force to the bike, and a controller 201 operatively connected to the motor 205, the controller to control the electric motor 205 using the air speed sensed by the air speed sensor 218. The controller includes a set electric-motor parameter for the output power of the motor. The electric motor parameter can be bike speed. The controller can also use ground inclination to determine the power to be output by the motor to assist in powering the bike. The controller can use ground inclination to determine the power to be output by the motor to charge a battery in the bike. The controller can set the power of motor assist to be greater in a greater headwind than in a lighter wind. The controller uses rider weight and rider height as parameters for controlling the motor.
