(c ) is capable of being propelled by muscular power,
(d) has an electric motor only, which has the following characteristics, namely:
(i) it has a continuous power output rating, measured at the shaft of the motor, of 500 W or less,
(ii) if it is engaged by the use of muscular power, power assistance immediately ceases when the muscular power ceases,
(iii) if it is engaged by the use of an accelerator controller, power assistance immediately ceases when the brakes are applied, and
(iv) it is incapable of providing further assistance when the bicycle attains a speed of 32 km/h on level ground,
(e) bears a label that is permanently affixed by the manufacturer and appears in a conspicuous location stating, in both official languages, that the vehicle is a power-assisted bicycle as defined in this subsection, and
(f) has one of the following safety features,
(i) an enabling mechanism to turn the electric motor on and off that is separate from the accelerator controller and fitted in such a manner that it is operable by the driver, or
(ii) a mechanism that prevents the motor from being engaged before the bicycle attains a speed of 3 km/h. (bicyclette assistée)
Each province must follow these laws.
