Pedal assist bicycles are considered equal to traditional ones, in compliance with European Regulation 2002/24/EC. Installing a child carrier on such a bicycle does not entail any problems, but it should be considered with caution. Child carriers are designed for urban, tourism and moderate trekking use; they are not designed to be used on means moving at high speeds or dedicated to extreme uses (professional mountain bikes, racing bikes). Their installation on mopeds, scooters and the like is prohibited. Therefore, a child carrier can be installed on pedal assist bicycles, which are equivalent to traditional bikes, as long as they are used at a moderate speed and with the caution required for carrying a child on the road. Different story for power assisted bicycles equipped with a motor that can keep running even if the rider is not pedalling. According to the current regulations, these vehicles are comparable in all respects to a moped; therefore, a child carrier must not be installed on this type of bicycle. The same thing can be said for bicycles that are equipped with a motor that runs both on pedal assist and as both standalone motor.
